Re: Need Help Repairing 60" Lg PN5700 Plasma tv
I manage to swap out the ZSUS board....but still no change. Now im leaning towards the YSUS board and buffers being bad.
This would be the 2nd time I would be replacing these boards.....what would cause the ysus to keep going bad?

The VS (205)/VA (55) voltages check out to be typical on the X-sus board.
Let me check the Fuses....will get back to you guys......Last edited by navamous; 05-23-2018, 10:10 PM.Leave a comment:
