Question about Televison & Video
I have a Sony Trinitron KVG21Q1 TV. When i switch ON the TV
it automatically switches back OFF in about 2-3 seconds. Sometimes i see
athin silver line in the centre of the display also none of the
lightsin front flashes. What is the problem with my TV?
It is about 7 years old. I was advised by a person, to check around"Vertical Out" area to see if there is any dry solders but i didnt findany.Also i checked the whole board for any dry solders or any shorts or for any burnt components didnt find any.
The tv is old but my grandparents use so it not muchused and they dont want to go to a new one as new tvs are complicatedfor them to use.
The vertical IC is faulty and needs to be replaced. Look for a small flat IC attached to a heat sink. It will be marked LA7837 or something similar. Replace that part and update this with your results. That may resolve the problem or at least get you a distorted picture which will indicate a few other parts that need to be replaced.
Keep us posted.
