Hi Friends
My 32" lcd tv has no picture(grey screen when it is turned on) but the sound is OK.After a a few book reading i found One bulged capacitor(680uf,35v) and replaced that on the power supply,but the TV still has no picture.So i was hoping one of you experts to lead me on right direction.
I need a voltage schematic which show me what voltage do i get from Power supply (Beko z1j194-07) to main board and so on..I mean which pin must have how many voltage or ...
Ps. I am very new in electronic but i hope i learn some from you guys

I really appreciate any help you can provide
