Since it is 5 years old mostly dry soldered appears. First sort out the soldered problem. Then check zener diode in video input path is short. Mostly the diode is short. Still get problem check video switching ic also. I think former is the most problem.

If there is sound, no doubt, its signal input is OK. The problem must be to your Tv itself. If the LVDS cable, the cable that connects between the T'Con board and LCD panel have a loose contact, this type of faultcan occur. Re-seat this cable once, and check.

Sounds like a video cable issue, i would change your video source cable and if that does not do the trick, try switching inputs all together, if your using color stream 5 strand go to HDMI, DVI or svideo.

I bought a 3 year old Sony FD Trinitron WEGA KV SW29M50 29 and it did not come with a manual question thereare 5 jacks above the video jacks what are they for i have surround sound speakers how do...


The inputs you refer to should be colored as follows.
Red
Blue
Green
Red
White
(not necessarily in this order)
These are what are called Component Video inputs and is one of the way that HD capable equipment connect to your television. It will not get true HD picture but this input will provide you with a crisper clearer picture.

Good Luck and Happy New Year.....

Do you get this accross all inputs on the TV? if so then you have a problem in the video switching circuit causing a loss of both color and video information.
