Sony Bravia TV red LED blinks 4 times

Question

Hello,
I have a Sony Bravia TV that won't turn on.
Description of the issue:
When I start the TV, the green light turns on and after a few seconds the red light blinks 4 times every 2 or 3 seconds (the screen remains black).
I wanted to know if anyone can help me troubleshoot my TV.
Regards.

Joel

This is an electrical overload problem with the TV protection circuit;
The solution is very simple:
You need to disconnect the power cable and connect the two prongs of the plug together for at least one hour to allow the protection circuit to discharge.

Gaston,

My TV is working now.
Here's what I did.
Turn on your TV and press the mute button for at least 3 to 4 seconds.
Then press another button that is to the left at the top of your remote.
I'm not in my country at the moment.

Try that and let me know.

Thanks

Joel

Hello,
I'm sorry, I don't have an answer. But we also have the same problem with our Sony Bravia TV. And we would like to have a solution.
It happened after we had an electricity problem. There was lightning that struck near our house and the TV broke down along with another device. We would like to know if it's possible to repair it and how. It's very important.
Thank you in advance for giving us a response if there is one.

I have the same problem, it blinks 4 times every 3 seconds, what should I do?

My Bravia stays black and after a few seconds a red LED blinks (5 times repeatedly). It's 4 years old and I'm low on funds. If anyone has an idea about the malfunction, it would be appreciated.

I have exactly the same problem! It has been recurring for several months, usually I unplug the TV for a few minutes and then everything restarts normally. But this time, no way!

Well, I just tried Joel's trick with the mute on the remote, and it worked. Go figure ...

I contacted Sony and received the following response:
"Only an examination of your KDL-32L4000 by a specialized technician will allow for an accurate determination of the cause of the symptom you described. Therefore, I encourage you to entrust your device to the After-Sales Service of your distributor. They will be the only ones capable of applying the warranty you have contracted with them.
It is also possible to drop off your KDL-32L4000 at the After-Sales Service of another retailer if they accept to take it on."

In other words, nothing, except for a specialized technician who, despite an error code, can’t provide any information; a distributor who will decide based on the warranty (more than 3 years, hello warranty) whether or not to accept the service.
SO BACK TO THE GARAGE AND PAY AGAIN.

THANK YOU, SONY.

Thanks to Joel because the Mute manipulation (held down until the image returns) + top left button (input selector on my remote) seems to work on my Bravia KDL-W5500...
I was getting 10 red LED blinks between each pause even after updating from 1.741EA to 1.750EA.

Good luck to those out of warranty, I always opt for the 5-year warranty extension, especially considering the price and size of the device if it needs to be taken back to the store ;)

Hello,

I have exactly the same problem. It goes into sleep mode right away and flashes 4 times....

I just spoke on the phone with an authorized service center who told me that the issue might be "the panel"....part still available but it costs 500 euros!!! excluding travel and labor....

However, there is a possibility to contact Sony to ask for "compensation" and they can contribute up to 50% towards the repair...

That said, the service center advises me to buy a new TV!!!

And it won't be a SONY.

CHRISTIAN · Answer

TRY THE MUTE BUTTON (SOUND CUT ON THE REMOTE CONTROL) when starting up; it works 80% OF THE TIME.

igwane · Answer

The mute button works great for those problems....

kazham · Answer

For my part, it's about the mute button.  My TV was purchased in December 2011, I thought I would be safe with Sony but well...  Thanks for the fix.

thierry · Answer

Thanks, it worked with the mute button.

blaric · Answer

If your Sony TV blinks 4 times, it means you need to change the inverter, reference A06-126268 for the model KDL-40S2000, etc...

Hello  I have the same issue as you, it blinks 4 times, the remote control trick worked 3 times but the problem came back after a few hours  therefore I don't think it's a fuse issue  I suspect the inverter board but I'd like to hear your opinion  thank you

JOJO · Answer

Hello,

I have exactly the same issue. I turn on my Sony Bravia from 2006 and it turns off after three or four seconds, the green LED lights up and the red one blinks four times with two or three seconds in between.
Personally, I've done the steps you mentioned and it still doesn't work. Should I throw it away?! Because this is really starting to annoy me!!! :-D
THANK YOU IN ADVANCE FOR YOUR HELP.

pagoturbo · Answer

Don't throw it away, give it to me!  Being serious, I fixed mine by re-soldering the fuse on the inverter board.

Kev · Answer

My Bravia flashed red 8 times in a row without turning on (even trying the famous Mute button)  I changed the socket it was plugged into and everything works perfectly now.

iniactiviti · Answer

Hello, I have the same problem as the first question (I turn it on, then it turns off, then it blinks 4 times within a 2-second interval). I checked everything (fuses, power capacitors, etc.) ... But I still haven't found a solution!!! I'm attaching photos of the brown board and the fuse: Photo n°1: https://www.casimages.com/i/130508035025708664.jpg.html Photo n°2: https://www.casimages.com/i/130508035242327382.jpg.html Photo n°3: https://www.casimages.com/i/130508035339909747.jpg.html  PS: This is a Sony Bravia KDL-32S4000  Best regards.

Hello, I'm new but I believe I've found a way to fix it, but it requires a bit of know-how and soldering skills.  That's all  no spare parts the same day  just a little fuse to change, I specify that it is miniature!!!  I've been searching for over a year  phew, I  got away   from astronomical quotes and technicians like Darty   even though I have nothing against them, just their after-sales service which is quite expensive since they do standard exchanges under management orders...   so here, just in case, call me  www.joker57.fr   p  s I'm a taxi.

You need to update the firmware (software) on the Sony website via a USB drive. Have a good day!

Hello everyone,

I resolved this problem at home on my SONY BRAVIA KDL55HX820:
the same problem was noticed where the TV turns on and then after 5 seconds it turns off and the red LED blinks 4 times repeatedly.
Given the price of the TV, it's worth looking around online...

1: I found a table that defines the meaning of the signals emitted by the red LED depending on its number of blinks
2: Thanks to this table, I identified the issue: 4 blinks = Backlight problem.
Indeed, after several attempts to turn on the TV, a spot in the lower right corner was darker than the others. For the test, I connected my laptop with a VGA connection and opened the Paint application in full screen to get maximum white across the TV; we turned it on and then off after 4 seconds (before it automatically shut down), which left a few seconds to see if there was a defective area.
3: Disassembly of the TV to find the references of the board that manages the backlight in my case SSL4055_2E4A
4: Finding a seller—24€ with shipping from a Chinese vendor... price in France around 120€ but not in stock
5: Reassembly of the board
6: The first attempt failed, so I tried a second time with the MUTE+SOURCE button combination after turning it on. This combination may allow a reset of errors during its startup cycle.
7: Victory!! While my repair quote was 1450€

Out of curiosity, I looked closely at this famous board; I noticed it's very small but visible on one of the 6 main chips there's one that has a charred spot.

There you go, if this can help someone, I don’t have more information to provide. Good luck!

LudoTITANIUM · Answer

Kikoo everyone  Error code 4 indicates an inverter problem, check the 18 or 24v power supply that comes from the power supply, and the fuses on the inverter module..........  The inverter is the module that powers the neon lights for backlighting..............   Observed problem: the TV turns on then after about 5 seconds it turns off and the red LED blinks 4 times in repetition. Given the price of the TV, it's worth looking a bit online...  1: I found a table that defines the meaning of the signals emitted by the red LED depending on the number of blinks 2: thanks to this table I identified the problem: 4 blinks = Backlight problem. Indeed, after several attempts to turn on the TV, one area in the bottom right corner was darker than the others. For the test, I connected my laptop with a VGA connection and opened the paint application in full screen to have maximum white on the entire TV, we turn it on and then turn it off after 4 seconds (before its automatic shutdown) which leaves a few seconds to see if an area is defective. 3: disassembly of the TV to find the references of the inverter board, the one that manages the backlighting in my case SSL4055_2E4A 4: find a vendor, for my part 24€ shipping included from a Chinese seller... price in France around 120€ but product not in stock 5: reassembly of the board 6: the first attempt failed so I tried a second time with the combination of keys MUTE+SOURCE after turning it on.

Hello, my name is Afanou. I bought a Sony Bravia LED 41B 80.0 television, and my screen got broken during air transport. Since you have an intact screen, I suppose. My TV's board is working fine; it is intact. We could arrange something if possible. My number is 0754161819. Thank you.
