Question about Sanyo DS27930 27" TV
Screen periodically goes black, audio still works. A sharp tap on the outer case restores picture, but problem repeats 20-30 minutes later. Took it to a shop last week and they replaced the vertical card and a couple of capacitors. Got it home, still has same problem. Before I take it back to the shop, can you offer suggestion as to what is wrong? -Randy B.
There is no vertical card inside this set. Its the simple unexpensive vertical output iC. you most likly have a cold solder connectiion, on or about the flyback transformer, or video circuit in the TV set. Good Luck Please do not forget to rate this thread.
