Hi guys i have a problematic LG plasma.
It first came with a no picture fault , after checking i ordered a Ysus main board. it cured the fault, however2 weeks later the tv was braught back with the same fault, ive since ordered and returned 4 used boards from different supplyers.
I have tried the control board, but im still getting no where.
the fault is sound but no picture, all voltages are correct, buffers look to be in good nick with no bulging i can see.
I could use some help here as ive had this tv in for a month and understandably my customer is getting annoyed.

Cheers

Have you checked the buffer ic's? I saw on some forum there was a way to do it.
