Question about Flat Panel Televisions
I am working on a 26 inch lcd flat panel. It started blowing a fuse and would blow fuse again as soon as replaced the fuse so i replaced faulty parts by exchanging parts with another lc26sh12u i had with a broken screen. Now fuse no longer blows and tv powers on but all i get is a blue screen and no menu or any kind of display. it will not respond to remote menu commands or any kind of button command. It only turns on and off with remote or with tv buttons can anybody tell me how to fix this problem?
As you have a good screen, I would check ebay for the display controllers as there are so many available after shipment drops and kids with hard toys.
what you have been troubleshooting so far is analog , now its likely a digital issue , all you can look for is the the cpu is running,
is it getting the 5v + and the say 20 or so volts.
