I am probably going to sell / junk this thing.

I was watching it late one night last week and it shut down on me and gave 4 red blinking lights. I pulled the back cover off and after reading online thought I just needed to replace the power board. Bought one new and that did not fix it.

After a little fiddling around with unplugging cables and plugging them back in, I got it to stop the red blinking lights, but now there is no picture and only some ambient music playing on a loop....

I am ready to get rid of it and move on.

If anyone in Houston is interested in a 65" TV that needs "something" fixed on it let me know.

-64.5" screen (measured diagonally)
-Ultra High Definition TV with 4K screen resolution (3840 x 2160 pixels)
-3D TV (includes 2 pairs of active 3D glasses)
-Dynamic Edge LED backlight local dimming for excellent picture contrast and black levels
-X-tended Dynamic Range technology delivers 2X the brightness range of a conventional LCD
-4K Processor X1 engine and 4K X-Reality Pro upscaler
-PlayStationNow PS3 game streaming (built in)
-Internet-ready Android TV with Google Cast, voice search
-powerful built-in front-firing speaker system (12.5 watts x 4, plus 20 watts x 2 for the woofers)
-two remotes: a One-flick touchpad remote control, plus a standard IR remote

Paid nearly $3,000 for it in 2016
I'd sell it for minimal $ just to be rid of it

If no one is interested - where do you take something like this to dump it? Would a pawn, donation center, or repair shop take it?

I'm continually amazed at how much more costly Sony TV's are than everyone else. Our first big 1080p HDTV was a Sony. Ultimately, put it in an auction sale along with other furniture. I think we got about $10 for it.

I've helped you none.

That's the main board? Hmmmmm.... I might try that as a last ditch effort....

This may be a silly suggestion, but have you performed a hard reset?

I had a similar issue with my 2017 Sony two different times that were each solved with a hard reset.

Tried numerous times; holding down the power and vol- buttons while plugging in the RV; waited for green light; released buttons.... no fix

I have this same tv, and I've had boot loop issues. I just unplug it for about ten minutes then do a hard reset.
