Question about Sony FD Trinitron WEGA KV-34XBR800 34" TV

2 Answers

No picture No Sound

Stand by light flashes 6 times pauses and repeats. At first I would turn off TV for an hour and then it would cut on like normal. Can you direct me to the replacement part and let me know the cost? Aslo let me know the difficulty level of the replacement.

There are several thing to check that can cause this type of problem.
CRT televisions, Espcially SONY need to warm up and will have sensors to detect when they are at the right temp before they try to display a picture. Sony does this so you get a nice presentation from black to picture rather then seeing a picture enlarge as it powers up.
The list of things to check start with the degausing coil around the tube and end with the tube itself. the rest of teh list is most every IC in the darn thing.
also all power supply voltages need to be verified.
Unfortunately repairing CRT televisions is one of the most difficult tasks for even skilled service people. Especially when you dont have a proper service manual.

Our Trinitron KD-27FS170 Tv will not turn on. It sounds like it is turning on/off but no picture or sound. The Stand-by/Timer red light is flashing 4 times, pause, then 4 times, etc.


This typically means you have a bad capacitor, you can inspect for any swollen or bulging capacitors however unless familiar with desoldering boards best leave it to a repair technician.

Un plug and let stand for one minute. If it still does blink then use the reset on the remote and press it while pressing the power button on the TV.

My sony wega tv is not staying on it turns off when the standy by light turns on


Mine just started something similar. When I turn it on, you get sound, the red light flickers, then before the picture comes on it cuts off. Sometimes I can spend an hour or more turning it on over and over again until finally the picture comes on. This TV is not old - only a couple years old and I spent alot of money for it as it was a more expensive model back then than they are now. Well, they don't make them anymore, but anyway it still cost more than a comparable plama HDTV. I think this really sucks!
