LG Plasma not working Solved/Closed

Question

Hello,
My LG plasma TV 42PX4R purchased in March 2006 is broken. The screen does not display an image, but the sound works. It’s not a connection issue; I’ve checked everything, the message “no source” doesn’t appear, the screen is completely black.
LG’s customer service has been useless since the device is no longer under warranty; they have not offered any solutions or provided the address of an authorized repairer in the Paris region, and they don’t want to help at all!
I contacted a repair technician who told me that he couldn’t find LG parts, and he advised me to get back in touch with customer service.

Do you have any advice for me, please? Thank you.

Configuration: Windows XP Internet Explorer 7.0

I have a solution for you all: unplug the screen and wait 30 seconds, then remove the metal cover behind the screen. Once removed, observe the different visible boards: generally one in the center called the motherboard and two on the sides x and y. Now look: there are on all these boards round and cylindrical components standing like towers. They are called capacitors. Observe them well: the top should be flat. If they are bulging or there are dark burnt marks, they are dead (lifespan 3 to 4 years max compared to at least 10 in the electronics store). Therefore, you need to take their reference: voltage, etc... go to the local electronics store at 1 euro each, then desolder the defective components and replace them. In most cases, the problem comes from there, and one time out of two the device works again as long as no other damage has been caused elsewhere.

Don't thank me, thank all those manufacturers who choose to use defective or low-quality components to reduce their costs and, moreover, contribute to making you spend money regularly in our beautiful consumer society.

Hello,

My LG plasma 42PC1RR 107 cm has also broken down. It is from June 2006, the graphics card was already changed in December 2006, and now there's no picture, just sound, and of course, it’s no longer under warranty.

While browsing various forums, I saw that many of us are in this situation, after 2 years, the cards fail. Repair shops charge between 400 and 600€ on average, and I've even seen some say that they are irreparable. In fact, many sell their plasma as is for around 100 - 150€...

LG doesn’t care about us because a TV at this price lasting only 2 years, 2 and a half years, is outrageous. The TVs from before easily lasted 10 years.
I also saw on a forum that there might be a manufacturing defect in the ribbons that could fry. For that, I’m going to dismantle my plasma and inspect everything.

I don’t know if we could take any action against them, as we are quite a few in this situation and there is indeed a construction problem if it fails like that, don’t you think?

If anyone knows exactly what to change, please let me know, because we're talking about 2 cards, Y and Z, so which one?
Thank you!

Hello, I have an LG 42 inches too, and the problem seems to be the same for everyone.  Thank you.

If this continues, it's better to write together to LG and ask what is going on and to make a petition. They have messed with me too... I contacted them about my LG for 2 weeks and the repair cost is 400 excluding travel, and besides that, they repair it and LG will decide if they reimburse me, but with the current crisis, no way. So I have already sent emails to everyone I know with the link to the discussion board that we viewed. Because they avoid buying a product again that is made under conditions that are not European, but where it is humid, and that in our market it doesn't hold up. I also blame myself for buying this brand, so the workers are paid like crap... And from now on, I will only take models sourced from Europe and no more of their cheap stuff with poor calculations, and moreover, they are ruining the European market. There is one unhappy customer, rrrrrrrrrrrraaaaaaaaaaaaaaaaaaaaaaaaa.

ric · Answer

Everyone completely agrees with you
but do you know Dutch
but you know how to speak English
Do you speak German?
Well, we’re not going to talk about the linguistic problem, okay
if you already know, it's fine and here my clients who give French lessons say that it's a waste of time
it's better to learn how to calculate and I did my calculations, let’s screw them over
and now he speaks Chinese or Japanese
thank you to the grumpy person

Lunaelza · Answer

Hello everyone,  So, following my plasma issue, I contacted the technical service at the request of customer service, who clearly told me that they didn't understand why I was calling since it was no longer under warranty. I replied, "So what?" I continued talking about the problem, asking them to cover the repairs (at the request of customer service) because of a manufacturing defect on their part, vice of whatever.... Anyway, the guy tells me he's forwarding my request to a manager and that he would call me back in 3 to 5 business days.  Date of the call: 01/28/2009, to this day no one has called me back. It shows they have something to hide. I then sent emails to LG cursing them out and threatening to involve an expert and file a lawsuit. A TIP: do the same (on the LG website in contact us, send them emails)  However, I advise against spending money to repair your plasma; once repaired, you'll have a black band on the side that will remain or disappear only to reappear... and it still won't be covered under warranty so you'll have paid for nothing. I've also heard that some Samsung and Thomson plasmas do the same, so be careful. LCDs are therefore more reliable, and as far as I'm concerned, I boycott LG and I say it loud and clear.  Good luck to you.

Hello everyone,

I’m here to add myself to the list for the screen 50PY2R that just broke down. While I was watching TV, there was a noise, then the picture disappeared but the sound is perfect. I took it apart but don't see anything suspicious. Has anyone managed to fix theirs?

seb · Answer

Hello everyone, I have the same problem; I bought my LG 42 PX 2 RVA plasma 3 years ago. There’s no picture but the sound is fine. I will contact a lawyer tomorrow to see what advice he can give me, but I think we all need to come together to take action against LG and get justice. I paid 1750 euros for mine back then; that's an expensive bill for 3 years.

My LG 42 PC 1 RR failed last week on its 3rd anniversary!!!

I will receive the estimate from Darty, but I’m convinced that the X and Y boards are dead.

It really sucks, over €2000 back then...

If anyone who has tried to take action has been successful, please let us know how to proceed.

Thank you

Pop · Answer

Same problem for 2 days: I was changing channels and crack! ... a big sudden crack, then no picture ... the sound is still okay. I have a 42pc1d, bought in April 2007. How can I fix everything???

bigoudi · Answer

Same problem as you, no more image!!!!!! I have a great radio, same thing, broke down 2 months after warranty.

Sent it to the factory, 3 weeks later, great response, too expensive to repair, no explanation, I'm not a technician, problem with the bulb, panel, circuits... they could have been more specific.

LG, done, no way, some garbage...

stipe · Answer

I've been fighting with LG's Sales Department for two months. So far, they're playing dead... But I'm going to hound them!!!

Lunaelza · Answer

Hello,

To respond to Bigoudi,

No response from LG, they're playing dead!!!

In any case, I'm not giving them any publicity; every time someone in my circle talks about plasma... I tell them to definitely not choose LG for anything. And I can tell you it works!!!

If anyone has news about lawyers, UFC QUE CHOISIR, or any advice on how to take action against LG, feel free to spread the word. The more of us there are, the better our chances of winning.

I have read the messages on this forum and I also have an LG 42Pc1RR plasma TV with a black screen but sound is working. I’m with you for any collective action.

bouli2 · Answer

the TV is out of order, the source of the fault is the SCREEN; LG does not provide this part for repairs, manufacturer’s warranty expired and CAMIF warranty void (business ceased), so no more television -1000€ gone up in smoke the repairman is AAVI in Lesquin (59) reliable: LG authorized

DOMI74 · Answer

Hello having my plasma broken down, I got a quote at Darty  458 euros for repairs.

BOULI2 · Answer

DON'T WASTE YOUR TIME OR MONEY. Change your TV and brand, as the defect is recurrent (about every 2 years).

kimiseb · Answer

Hello, following a failure with my LG plasma 50 py 2r (like everyone else = no picture but sound works), Darty gave me a quote and it's the Y board that is burnt out

not sure if LG still has it in stock and I might not be able to repair it

so I'm going to sell it as is, I think

I paid 4299 euros in November 2005 and it didn't last 4 years!!!! such a shame

Fnac doesn't cover it, and LG couldn't care less

so if someone wants it for parts, it could work

best regards

loubets · Answer

I own, along with a friend, an LG 42PC3R plasma TV purchased three years ago. (We bought it at the same time). Today, the TV displays a multitude of red dots on almost the entire surface of the screen. I contacted LG's customer service, who replied that this problem exists with all plasma panel manufacturers (in short, it’s total nonsense). Do a Google search with the keywords "red dots Plasma," it's enlightening. For me, LG is finished for life, and I encourage you to turn to a more serious brand that doesn’t treat its customers like idiots when you buy your next TV, whatever the technology.

lolo76 · Answer

Gentlemen,

I received some good news at the beginning of this year.

After some bad news which was:
- After being sent for repairs, the estimate for the screen replacement was 996 euros
- received 500 euros from insurance when I paid 1590 euros back then.

So we wrote a stern letter to LG:

Outcome after sending the TV to LG:

Received from LG: 51% of the value in gift vouchers for the entire multimedia service (that’s 754€ after deducting transportation costs).

So we bought a computer and a TV.

In short, the only way to make yourself heard is to write a stern letter stating that the issue seems to be recurring and is due to a material problem.

There you go, get your pens ready.

tchina57 · Answer

Here it is!! It's my turn, my LG plasma 42PX3RVB-ZA 107 cm just broke down. When I try to turn it on, there’s a little pop and... nothing. Not even sound like some testimonials say.

My husband thinks it might just be a simple part that failed when turning it on (like a fuse).

Has anyone encountered this problem?

Thank you to the brave soul who will answer me,

best regards

P.S. it would be 5 years old in November 2010!

Davidhoff · Answer

Hello everyone,
After thorough research, I managed to fix my LG plasma TV.
It now works like new.
The model is PDP42X30001.
The issue was the following: sound but no picture.
It's not easy to explain the actions to be taken.
If you're in the PACA region, contact me... it will be simpler.
See you!

stphane7117 · Answer

Hi since this afternoon, here I am with an LG plasma with no picture but sound is okay. I heard a small snap and then no picture anymore. Could you please advise me on troubleshooting? I can call you if needed, thank you in advance for your response. Stéphane

sam · Answer

Here I am joining you... after an image that was becoming increasingly mediocre, my LG 107 plasma kicked the bucket—no more picture, but the sound is fine. It was extremely hot; the fan wasn't turning anymore, and it overheated. After opening it, there were no visible anomalies: 4 fuses okay, no swollen capacitors, so if someone who knows more could help me...  Thanks in advance for your help...

A small technician's observation on the side: The only plasma TVs that hold up are the Panasonic ones, from the Matsushita group, which, let’s remember, is the world’s leading manufacturer of consumer electronics. P.S.: I don't work at Panasonic.

PTITGREG45 · Answer

me too a 127cm plasma bought for 1307 euros less than 3 years ago I’m furious, plus the warranty has expired.... It doesn’t even turn on, it goes green but 2 seconds later it goes back to standby and there’s no way to do anything. No sound or screen...HELP

Tom · Answer

There can be several problems from the smallest to the largest!

Often, this comes from an integrated circuit located underneath an aluminum radiator, on the YSUS board, which is short-circuited (the CI value is approximately 30 euros).

This could also be due to one or more faulty electrolytic capacitors on the power supply board; at worst, it's the panel, but to be sure, you need a diagnosis from a professional.

I have already repaired faults of this kind for 150 euros and sometimes much less; the problem is that I'm from the 80s and probably quite far from you!

BRISSON · Answer

Hi, I have the same issue with my LG plasma 107 cm from 2006, no image but sound is still working, do you have a colleague or peer in the Nantes area? Otherwise, if I send you a photo of the back, could you help me locate the capacitors or the IC at fault? I have a friend who repairs TVs and could take a look at it.  Thank you for your response,

kupidon77 · Answer

Hello,
Like many, apparently, my LG plasma TV 50PG2500 just broke down 3 weeks after the warranty expired. Black screen all of a sudden, sound is okay, green light is on.. Has anyone found a solution? Can the repairs be done at home? Is there any way to do something against LG? Thank you for your help.

AIMEDIEU · Answer

Same story with an LG RZ42PX11. THANKS to those of you who tried the repair methods proposed here to let us know how it turned out.

For reference, a little very old story that gives reasons to believe in simple solutions.

First generation Macs (the small boxes with integrated black and white screens) had legendary reliability. However, after about ten years, those that had been used daily ended up experiencing a display issue. It was enough to open them up, locate the defective solder (a brownish area easily identifiable), a little touch with a soldering iron and... they would work for another ten years.

So... as in the case of these LGs, reading all the posts on this forum, it seems that the common point among the various faults may be due to overheating of components or fragile solders, if someone has developed a reliable diagnostic method... THANKS for sharing it with us.

nico13 · Answer

Hi, I have the same issue as you, it comes from the Y board, there's a 99% chance of that. The problem is that you need to contact an authorized LG repairer. Good luck.

CandyFana · Answer

Who could give me a helping hand? I have the image but it's shifted down. Every electrical action like switching sources between the DVD and the decoder, or turning the TV on and off, or worse, just turning the decoder on and off, is enough, and boom the image is back to normal. Then a few minutes later, boom, the image shifts down and there's a 10cm black strip at the top.  If it were the panel, I would have nothing left. Yet, if I restore an electrical contact, boom, it’s back to normal!  What could have broken?

CandyFana · Answer

I called Hisense in Belgium and, as always, it's the kindest customer service out there.  After listening to me, they think it could be the power supply and directed me to the authorized repairer near my home. They made sure to tell me to say that I came from them and that if there were any issues with the repair or assistance, I should give their name and say that they could call them!  I should receive a call from the repairer tomorrow. They were very kind as well.  Honestly, when it comes to customer service, there is NO ONE who surpasses them. I actually called 15 minutes before the end of their working hours.  Let's hope it really is the power supply and that they can repair it for a reasonable price and at my place.

cyril 62 · Answer

Good evening, I own an LG 50PQ3000 and I've just encountered a similar issue of no image but excellent sound. Of course, it failed on me after one year and one month to the day! So I went to Gitem to have it repaired last Thursday and got it back this Friday! The repairman informed me that it was just a component that needed replacing! Anyway, after an hour of use, the TV exhibited the same symptom again! So tomorrow I'm going back to Gitem (the labor for the intervention is guaranteed for 3 months). For now, my LG plasma has cost me 77 euros! Next time I’ll do it myself and I’ll sell it, goodbye LG and Samsung! I hope this helps you avoid a board replacement...Best regards, Cyril

oz77330 · Answer

Hi guys, I had the same issue as you, couldn't turn on my LG plasma even though the green light would turn on and off a few seconds later.
The solution is simple and costs about 20 euros. "Labor and 3 capacitors to change"

- Unplug the power cord
- Remove the back panel
- Remove the board in the center and at the top of the TV
- Take this board to a TV repair shop and ask them to change all the swollen or leaking capacitors "10v 330uf 105°"
- Reassemble the board
- Plug in the power cord

There you go, the miracle should happen, lol. Keep us updated ++

Hello French cousin, I'm from Quebec and I have the same problem as you with my LG Plasma 50PS30, but here in Quebec, there is a law called LEGAL WARRANTY, which allows us to take action against the manufacturer.

Hello gentlemen,  I had the same problem with my LG? I changed the dead capacitors, and I also replaced the YSUS board. 210 euros at the store, probably cheaper online. But it is certain that the problem comes from this board, because like you, I had no image but sound.
