Update: found "part out" unit on Ebay for $49 + free shipping. Turns out it was in "protection mode." Correct button sequence restored power and it works great. Will part out my unit, noting HDMI PCB is inop.

HDMI PCB board is inop. Other parts appear to be in good condition. Jim

It appears to be corrosion. Top photo shows before and bottom shows after I cleaned it with electronic spray cleaner.

Unlikely I can fix this, as R2429 and surrounding area appears too corroded. Any sources for a used P.C.B YF985?

These may be the source of the problem. See images. Can these components be obtained individually and replaced using soldering iron? Jim

Hello Master Tech, I am now back online. Any guidance for testing these two ICs?
Best regards, Jim

Thanks for the reply MasterTech. What types of tests could I try, using my digital Fluke multimeter, to isolate the problem? Happy to give it a shot. BTW, I will be without Internet access for a few days, so will look for your reply when I am back online.
Many thanks, Jim

In No Protect self-diagnostic check (Tone+Info+Main Power buttons), an error is shown as follows: C1-6. BUS DSP:NGThere is no sound. There are no other errors shown. Neither unplugged from a/c, disconnected speakers, nor factory reset fixes the problem. Any suggestions on further diagnostics or troubleshooting options for this error would be greatly appreciated.
