LG TV suddenly quit displaying in 1080p

[rymgreen]

Hello. My 47" LG LD650 TV I purchased in Nov 2009 suddenly quit working in 1080p. I first noticed the issue when I turned on my PS4 and got grey static instead of any picture. My PS4, which is run through my Sony STR DH810 receiver, has never had its resolution settings altered in any way since I purchased it last July.. After booting in Safe Mode and changing the resolution to 480p, I discovered that every resolution EXCEPT 1080p worked just fine.

I tried all 4 HDMI ports on my receiver (didn't work) & purchased a new HDMI cable (didn't work.) When I plug the PS4 directly into my TV, instead of complete grey static, I get a 1080p picture that flickers non-stop. I tried all 4 HDMI ports on my TV, and the same thing happens.

To make sure it wasn't an issue with my PS4, I plugged in my Chromecast to all 4 HDMI ports on my TV, and get the same flickering issue. When I plug the Chromecast in to my receiver's HDMI ports, I get no picture at all - just grey static.

I have restored factory settings to my TV, updated the firmware, unplugged everything and re-hooked everything back up, and nothing has worked. Does anyone have any clue what the issue might be?

Thanks.

Since you have problems when you bypass the receiver that would indicate that the TV is at least partially at fault. Could be the input board or video board. If your could try the receiver with a different TV that would pin it down even more.
