Panasonic TC-P50G20 Random Static

[mfucilli]

Recently replaced my panels TXN/A1MGUUS (TNPH0834AE) A Board, as it was causing a 10 blink error and wouldn't power on. Replacement had the unit working fine for a few weeks now.

Within the past two days I've been noticing quick blips of static showing up on the screen. Happens very quickly and only noticed it three times so far. I have a Denon receiver hooked up to HDMI 1, and using a PS4, DVD, and Chromecast (all plugged into 3 inputs on the reciever). These flashes happened twice on the PS4 and once on the Chromecast. I haven't used the DVD in a while.

I'm thinking perhaps a bad HDMI cable, or is the new A Board faulty?

Maybe try recording the screen to capture this and post a still image if you can.

Is it like digital noise, like blocks?

or look anything like this?



These boards can have issues as they age or with heat end up with bad solders under the BGA chips I suspect.

I've had one generate random lines as pictured fickering and as the board heated got worse.

So it may be a sign of trouble, would need to see what it is if possible.
