Both HDMI inputs no longer working

We had a thunderstorm roll through and the following day, I discovered that both HDMI inputs on my Panasonic TH-42PZ77U plasma TV, no longer work. The TV seems to be working fine otherwise (I can access menu, etc), but I can't get any image to appear regardless of device I plug in (Xbox360, cable box, Roku, etc).

Edited with photos showing boards. I don't personally see any damage but then again I'm not sure I'd know what to look for.

Edit: I tested with an antenna hooked up, and the TV does show antenna channels. HDMI 1 and 2 show nothing (blank), Component 1 & 2 same, and Video 1-3 show horizontal green lines.

@redwing634 posibly your DG board that got damaged. Remove the back of your set and take a look at all the boards, but pay particular attention to the DG board.

See if you can make out any obvious damaged components. Post some images of your boards and their arrangements on your set with your question. For that use this guide

sounds like a bad mainboard.

oldturkey03 의 2017년 6월 21일

Which is the main board? And would the menu and antenna channels work if the main board was shot?

I'm considering buying a replacement board, but do you think the DG or Main(Power Supply?) board needs replacing? I was thinking the DG but looking for confirmation.
