Samsung pn51f5300af no HDMI

[Snype32]

I'm working on a Samsung 51" plasma. The tv powers up fine, screen is good. I can navigate the menu. Its self diagnostics find nothing. However the HDMI ports are not working. When I plug something in, the menu lights up the correct port as if its detecting some signal, but no audio or video come through. I'm assuming main/logic board issues? Is there something I can test, or do I simply need a new board? Any input would be great, Thanks!

I would first test the connections between the hdmi plug and the board, a few poor solder connections can result in the port being detected but you will have no video or audio. Use a needle to see if any of the pins are loose. I just repaird a different samsung main baord and both hdmi's had poor connections.

bad hdmi cable can do the same. Actually a new main board is surprisingly cheap for this TV.

I checked the hdmi connections...all good, and its a brand new cable, plus I have tried different cables all with the same results. Where is a good source for a replacement board?

Thanks!

Curious to know where I can get this board cheaply? Everywhere I have looked, the seem to be expensive? Maybe my idea of cheap is wrong.
Thanks!
