But if I'm unsure of what exactly I need to do it wouldn't be worth the investment for me to even try.
I wholeheartedly agree with that but you would need to do some investigating on your part to see if it IS a viable solution!
I repair X-Ray Equipment to Component level and I would need to get my hands on a Schematic and hopefully a Service Manual if available.
Scope out the PCB and replace the actual component(s) as needed, provided that it is not a Dual Layer PCB.
Ifr there is a HDMI Failure history then there should be a Component / PCB failure known.
If you have a relatively new unit and you are dead in the water via Warranty and Support, what do you have to lose.
I'd play with it a bit, but that's me.
Just a thought.
You would not be the only one in here that this happened to, I remember one other post about a bad HDMI PCB but his unit was "Under Warranty"
Check back through this Owners thread and you may find the post, IM the poster and find out exactly what was done to fix it.
Check out your Warranty and Amazon.
PS. If it's a Dead unit with no Warranty, I would like pictures of the Innards.
I won't open mine up because it is still under Warranty.
