Re: Panasonic TC-P50G20 HDMI Failure

Put the old board back in and it's back to how it was before, powers on but no HDMI. So I guess this board is going back. Just to make sure there's no procedures I should have to do to tell the TV to use the new board right? Should be as simple as disconnecting the old, plugging in the new and powering on right?

Got this one in eBay (high rep seller). Any reputable supplier for this type of thing or am I just going to need to try another chop shop?

Thanks!

So after replacing the A board now I'm getting 10 blinks and the unit won't power on. Does this indicate something bad with the replacement? Or something else wrong?

Have I done something wrong, or skipped some forum etiquette here? Please let me know if additional information is needed to provide any advice. Thanks!

Re: Panasonic TC-P50G20 HDMI Failure

Here are some pics of the back. There's nothing visually wrong that I can tell. Looking at the schematics it looks like everything with the HDMI should be contained on the A board, unless there was a general power failure, which I can find no evidence for (again with the aforementioned lack of direct voltage testing). If anything jumps out at anyone else, or if indeed the A board seems like a good bet, please let me know. Thanks!...

I had lightning strike the house and it turns out an XBOX that was plugged into the TV via HDMI was not on a surge protector, and since this time no HDMI ports receive input. The TV still appears to function fine (turn on and display a picture and navigate menus), but there just isn't a signal.

As such it seems perhaps the strike may have shorted out my A board (TXN/A1MGUUS), however I wanted to see if there are other steps I should perform to verify prior ordering the part off of ebay. I don't have ready access to a voltage meter or resistors, or much experience testing with such...
