When I try to turn on my TV (Sony Trinitron KV-29FC20B), the standby indicator blinks twice every two seconds and nothing turns on. Please help, thank you all.

I have the same issue as you, except that the standby light flashes when the television is turned on. Is this the beginning of the end?

Hello,  I also have the problem  does anyone have a solution?

franckj · Answer

I also have the same problem with my 82cm Sony TV.
I turn it on. The sound starts. No picture, and after 2 seconds everything goes off. The standby LED blinks 16 times!!!
Without doing anything, it restarted the next day as if nothing had happened, but the problem returned in the evening... What is it?

Hello everyone, I have the same issue as you, I looked at the technical review, it offers solutions for all problems except this one, how convenient!!!! I quote "The standby indicator is flashing: Please contact the after-sales service of your dealer."

Hello everyone, I have exactly the same problem; when I turn it on, I have sound but no picture, and the standby indicator is blinking. Can someone help me?

putchka · Answer

I opened the back cover, I removed the dust, but the problem persists, the standby indicator is blinking and the image appears after 10 minutes.
I think it's probably due to a faulty capacitor, if anyone has a solution!!!

tnt · Answer

I don't know if it's the tube, if it is, how can we change it?

tnt · Answer

How do I know? I've removed the cover, I see the tube but I don't know if it's burned out.

tnt066 · Answer

I don't know, I removed the cover but I can't tell if the tube is burnt out.

Hello everyone I also have the same problem of 2 blinks and a black screen. I called a specialist technician who told me that the blinking several times is a failure message. To interpret it like in cars, he needs to connect with a PC, and there he can see the failure pattern. In any case, he strongly advised me not to try too many manipulations, and unfortunately, I will be forced to go through the repair phase (...€)   Best regards, Serge

Hello, I am looking for the user manual for the television. Is there anyone who could scan it for me? Thank you in advance.

lagon11 · Answer

Hello, does anyone have the TV manual? If so, it would be nice to send it to me, I can't find mine ahhhhhhhhh moving house.

Good evening,

I can help you if:
1/ number of blinks?
2/ exact TV model?
3/ do you want to fix the TV yourself (or through a friend who is an electrician)?

If the LED blinks twice, it is likely a protection issue due to excessive internal current consumption.
This means that one of the power components is faulty (transistors, capacitors, flyback transformer, or CRT...)

Generally, it's the power supply that fails (transistors) in TVs, and any good repair technician can handle it for a few dozen euros. If it's the flyback transformer: a bit more expensive (around 150 euros?). Buy him the technical documentation online for 10 or 20 euros if he doesn't have it.

For SONY TVs like chassis FE-1 and FE-2 (like yours), there are many issues with the tube (unfortunately) which is quite fragile (ah, the good old CRTs from the '80s that still work...). After a certain time, the electrodes deform, and depending on the heating time each time you turn it on, it can cause various defects... There's no way to give you a single answer, but know that there is a lot of troubleshooting documentation for Sony TVs online, often for free... (many tips and tricks as well) If you feel like a handyman, please pay attention to the safety precautions when working on high voltage and the flyback transformer.

Well, I see that Sony has become real crap.  I have a 28-inch 28CS70 Wega 100Hz Trinitron from 2005 and I have the same problem when watching TV, nothing works, then when I try to turn it on, I get sound for 1 second and then it stops; the LED blinks red and green 4 times and the same cycle repeats indefinitely.  Anyway, I’m disgusted, especially since this TV was the best you could get at its time in CRT 28 inches, a 100Hz Wega Trinitron!!!  I bought this Sony 16/9 because I had a similar problem with a Philips 16/9 24 inches from 1999 that was barely 5 years old!!!  Anyway, Philips or Sony has become crap.  For the actual fault diagnosis, since my TV weighs 45 kg, it’s impossible to transport it to a repair shop. The last one I spoke to on the phone told me the power supply is dead, it's in protection mode, and the repair cost is €250!!! Others told me I should get it repaired, but since they only offer a 3-month warranty on parts, my Wega Trinitron 100 Hz is going to end up in the trash!!!  I’ve just ordered a 37-inch Panasonic Plasma, but this time I got a 5-year warranty.  P.S: If anyone can tell me what the LED that blinks 4 times means.  The exact model is KV-28CS70.

I have a Sony TV model KV-28FX20B, but the screen isn't clearing up because I'm a technician. I changed the 24C32, but I still have a vertical line; I can't get rid of this line. I think it's a memory problem.

Good evening,  my Philips TV model 21pt1354/48 stays in standby and blinks 4 times, what should I do? Please help me.

Hello everyone! I notice that my message from November 2007 has interested a lot of people. I found the solution for my television: I took it back to my dealer (Planète Saturn). They kept my Trinitron TV for almost (hold on tight) 3 months.  In the end, I think they didn’t find the problem or it was too expensive to repair (???) since they refunded me the TV based on the invoice and I was able to buy a smaller one, but in LCD.  Good luck to everyone!  "Intelligence is like a parachute: if you don’t have one, you crash!"

gilles16 · Answer

I have a Sony KV 21 FX 20B, same problem.
The picture suddenly disappears, the sound remains or the image is distorted and when you try to turn it back on, the standby light flashes.
If someone knows what this is, I'm interested!
Thank you

I have a problem with my SONY KV-29C3B Trinitron; it keeps switching between stereo and mono constantly, causing the sound to go loud and then low when it switches to mono. I would like to know what might be causing this.

Same problem, 27po kv-27fs320 2004, the standby light blinks 5 times in red.
When turned on, we hear the speakers as if it is turning on and off at the same time.
It lasts 3 seconds and then the standby light blinks. I would like to know if it can be repaired.
Thank you.

I took off the hood, cleaned off the dust, and punched the hood and the screen, and then the screen lit up. Alright, let me know if it worked.

Oh là là... it's discouraging... 37 inches??? Is that what they call 82 cm??? If so, I just bought mine 10 days ago and I'm waiting for the director's call for a replacement... I'm still not seeing anything happen...  I bought a Sony Bravia 82 cm... a sound that drives me out of the room, I hate it...  What should I do??  Thank you, have a good day.

Pourquoi mon portable Satio ne s'allume plus ? Le voyant rouge reste allumé, mais rien sur l'écran. Il n'a subi aucun choc. Pourriez-vous me dire ce que je dois faire ? Merci.

Hello, I have a Sony television model Bravia KDL 40 V 2000 that I bought in June 2006 for 2,810 euros. I have a problem: the standby light blinks for 4 seconds, then stops for a moment, then blinks again for 4 seconds, and so on. No image, no sound.  A repairman told me that he doesn't have a microprocessor chip to program it, and he says he can't do anything.  A 4-year-old Sony TV costs 2,810 euros, and I'm told it needs to be sent to  Sony. Where? Can someone please help me find a solution? Thank you for your help; in any case, I’ll never buy a Sony TV again, it’s crap.

Sorry for the delay in my response, but this site is heavily polluted by people who clutter the threads with their selfish little problems. It's a lack of respect towards the author of this topic ("cathyoucha")  Response: 1/ Unplug the sockets 2/ You just need to unscrew the screws at the back and then unclip the clips with a hard and flexible plastic blade.  But be careful nonetheless.
