Panasonic TC-P50G20 Going Into Protect

[mfucilli]

Hey guys, not sure if anyone can lend some insight...

I have a Panasonic TC-P50G20 that one day not too long ago turned off and kept making a power cycle clicking noise. I went through the service manuals and determined that it was an A Board failure and replaced the A Board (TXN/A1MGUUS) which seemed to have resolved the issue.

Jump back to the present and two weeks ago I started noticing that utilizing HDMI 1 on the TV started displaying weird anomalies... screen flashes, etc. So I hooked up HDMI 2 instead and had no problems.

Here's my setup... The TV is connected via HDMI to the monitor out HDMI on a DENON Receiver. Connected to the receiver in HDMI port 1 is a Chromecast and port 2 is a PS4.

Yesterday, as I was watching some Game of Thrones via the Chromecast, the TV turned off and started making the power cycle click noise. I unplugged the set and let it sit for a few minutes. It powered back on. Played some more video and about 5 mins in and the same issue happened.

So I removed the Chromecast and tried video from the PS4. 5 mins in and the same thing happened. I switched out the monitor HDMI from the receiver to the TV and retried. Same issue.

Now I removed the PS4 and connected it directly to the TV. Retried video and no issue.

The HDMI cable from the receiver to both the TV and the PS4 are older cables (5+ years). They are monster brand and don't appear to be kinked or split.

Now that the PS4 is connected directly to the TV and I'm having zero issues, my question is... is it possible the receiver is causing this issue? Has anyone run into this before? Or is it possible that it is the old HDMI cables? Or is there some anomaly on the new A Board I purchased and installed?

I should note the PS4 was tried in HDMI 1 and HDMI 2 on the TV now with no problems.

I was going to buy two new HDMI and replace the PS4 to Receiver and Receiver to TV cables and retest. But I'm not sure if anyone has ever noticed their receiver putting their TV into protect and what to test for there...

Ive had problems with 'MONSTER' cables in the past....

Two cables to be exact, both HDMI. One went intermittent, the other wouldnt work at all.

MEGA Expensive CRAP IMHO!

El-Cheapo cables from Home-Bargains have given years of service--With NO discernible difference in quality.

Its Digital signals after all, Not prone to noise or signal degradation over a simple cable, any that may occur is covered up/rectified by error checking etc...

NO point in mega-bux cables for HDMI. Its all marketing Bollox!

Not saying this is the cause of your issues, but cables could be worth changing just to confirm.
