I have a Samsung PN60F5500AF Plasma that has no picture. It has sound.
When it first came in, I put a meter on the buffer boards and had continuity from where it connects to the y main board and where it connects to the ribbon cables. I ordered new buffer boards and when I first unpacked them, I had the same reading. I contacted the seller and he assured me they were working. I thought I was testing them wrong. I installed the new boards and had the same result.
Next I ordered a new set of buffers from a different seller and tested them the same way and had continuity again. I figured I was doing something wrong and narrowed my problem down to the Y main board.
I ordered a new one and when I plugged it in, the resistors at the bottom of the Y main board ( R5084, R5097) started smoking. I replaced the resistors and they still smoked. I got another Y main and had the same result.
When I remove the lower buffer board and turn it on, there is no smoke.
Do I have bad buffers causing my problem?
I will try to post pics of the boards soon.
