Sounds like the y sus was blown out but what cause it. Were you careful when you were checking voltages? As long as you didn't short 2 components together, your y sus should be fine. Unless the y buffer up and/or down blew them out. Even the panel could blow it.
Basically you need a scope to adjust the ramps and everything. You can adjust VA and VS with a meter. If you don't have access to a scope, then just start changing the ramps etc by eye. It might take a little bit to get but eventually you'll get it.
SOURCE: while checking Vscan voltages on my LG du-42px12x picture died.
I have the same problem the pic went out but have sound. where do i go to get the Yboard? do i need a special number off of it or something? I took it to repair shop and he said it would be like 500 dollarss to repair. but i see all kind of yboards on ebay for like 150?? how do I know what one to buy?
