Newbie level 2
I have a SONY KV32S40.
When I turn the TV on, works ok, and after a few minutes, the Video shrinks vertically and goes blank. the audio still OK.
I change channels in this mode, the channels change because I hear differnt channel's audio.
I found from some reading that that it is a fault in the Video-Out section of the main board. When the fault occurs in that section, the safety circuit kicks in and turns the video off. Opened the back cover, spotted the video-OUT area, tapped and moved some components, and found that a cap 220UF, 50V (C540), when wiggled during a vertical shrink, when moved, caused the picture to come Ok.
Thought there must be a loose connection, and may be a defective cap.
So got me a new 220UF, cap resoldered (with proper polarity) and the TV worked fine for about 8 hrs continuously, and a few hours the next day.
The TV is again acting the same way as before, and i am wondering if there are some tips some one can share.
Would greatly appreciate the help.
Thanks.
