Question about Sony KDL32L4000 32 in. LCD HDTV

2 Answers

My 15-month-old Sony KDL32L4000 developed a problem, now getting worse. I have photos and a video on youtube of the problem. The top 15-20% of the screen (about the area you have for letterbox format) shows an almost perfect picture. below that is where the problem is growing. It now has a lot of ghosting of images, almost like an old-school vertical hold problem. initially the picture issue only appeared during bright images, now it is everywhere below the top region. It's out of warranty (barely). I'm capable of swapping boards, but if it's a display issue, I guess it's replacement tv time. My preference is to fix if economical.

    this isn't a software problem. Signal is getting 'clobbered' before it is displayed. What I don't know is at what point.

You have given a vivid report with knowledgge but I was wonderring why you did not swap the convergence board in the first place though you mentioned that it is within your reach.
Suspecting the LCD can be the last one and I dont think that it could have failed in such a short time.
So go ahead and change the con- board , fix all connectors- the one to the display screen tight- solder the points of connecctors or suspected areas.
It can be the failure of the IC,resulting in such wayward images but the board replacement will be the best for you.

Swapping boards will not solve this problem if you believe it to be a software issue maybe try restoring it to factory defaults if this does not work its replacement tv time

hope this helps

Have a Sony KDL32L4000. All of a sudden a dark spot has appear in the middle of the screen. TV is 2 years old. It is oval shaped and about 3 inches long. Is it a board problem ?Thanks

Call Sony right away. They have been having lots of issues with this model. If you are nice (and pleasantly) persistant you may be able to get a replacement at a reduced price. Definately talk to them about repair as well however many report their out-of-warranty (same model as yours) tv was not worth repairing. Many issues on the web for this model. In several of their models over the past 6-7 years there have been many class-action lawsuits. My in-laws got a brand new Sony 52" TV at 1/2 price because of all of the lawsuits over models before yours. They are likely in the mood to work with you right now.

Sound OK. When turn on TV, picture will go off and on about 15-20 minutes. After TV "warms up". stops doing this. But, seems to get worse as time goers by.

The video IC of the TV seems to have gone, not completely though. That is why it is malfunctioning. Please have it changed immediately.

Screen will not come on

If your screen is taking that long to turn it is a hardware issue with the screen and I would suggest contacting the manufacturer and try having them repair it at 18 months it still may be under warranty.

I hope this helped.

Thank you,

The screen is failing. A conductive strip from a flex connector to the glass panel is losing contact when cold. Any warranty left? extended warranty? Usually not repairable, screen has to be replaced and cost as much as a new set....
