Question about Sony FD Trinitron WEGA KV-34HS420 34" TV

1 Answer

My SONY Trinatron is starting to "blink", i.e., quickly pulse to a black screen. Each blink is about a second in duration. These episodes seem to vary from two or three blinks to as many as dozen. It has been doing this for over a month. At first, it did it for a few minutes when we turned it on. Lately it does it periodically even when the TV is warm. When it does this, we do not lose sound. We haven't moved the TV, so I do not suspect a wiring problem. I fear a more serious (expensive) problem. It is close to ten years old. Is this the end? Please advise. Thanks, John B

Sony KDL-52w5500 black screen 13 blink then 14 blink


You have a couple of problems if you are sure there are 2 different blink codes. 13 blinks indicates a backlight balancer error which would explain your no light condition. 14 blinks would be a TCON board error which is the driver board for the LCD screen. Either error would keep the screen black.

55 inch toshiba led tv audio sometimes gets garbled. must turn set off and on to correct


I have a Samsung 55 inch plasma that has experienced intermitent garbled audio, sometimes very frequent (a couple of minutes between episodes) and long in duration (several minutes). Switching to another channel and back would correct the audio.

I ran the auto program channel function a couple of times and it eliminated the gabled audio problem, except for infrequent (once every hour or two) and very short (a second or two in duration) episodes of gabled audio.

I found a thread on a CNET forum on this subject and it seems that the garbled audio problem affects a number of Samsung flat panel models.

SONY KV-20FV10 blinks off


Bad solder contacts on connector/component pins, oxydized connectors, dried up, inflated or blown electrolytic filter capacitors, burnt resistors.

Could be in the main or high voltage power supply, video section power supply, possibly in any of the other sections.

(these are just some ideas)

Sony kv35s66: No picture, just sound and red blinking


This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.
