where are you finding the TNPH0988 boards? All I have found is 2 on eBay for $300. My A board went out as well from a lightning storm. Can’t get a signal to my beautiful tv

shop jimmy is sold out and eBay wants $300 for the board, which I’m not 100% sure is the problem. Screen is fine when going through settings but i can’t send video to the tv. Does anyone know if a p65vt50 a board is compatible? Saw one for $150

My Panasonic TC-P60GT50 is almost six years old and it's as sharp as the day I bought it. I have considered going with a 4K TV but I hate to give up my plasma. I have not had any issues at all, and it's on at least 6 hours everyday. I also like having 3D. I know new 3D movies are not being made, but I have a decent collection of them, and I can find others used online.

Board part numbers are pretty specific to a particular model and even a particular size of the same model. Usually you want the replacement to have the exact same part number as the one it's replacing. A mid-year production change can result in a slight board change and the new version will have a different part number, and they are not usually cross-compatible. It might be better to just have your bad board(s) repaired instead of replacing it/them with used ones.

There are companies that can repair bad or blown boards. Some of em will have you send in all the boards and they'll test them, then fix the ones that need fixing.

Sometimes when one board blows, it takes another board (or two) out as they try to drive the crippled TV. You think only one board is blown, but after replacing it the TV still doesn't work because another one was bad as well. And that can damage a board again. It's just a good idea to have them all tested together.

FYI - When Panasonic Plasmas were being made (between 1999 and 2013) they would build extra boards and keep them in inventory to use for warranty replacements, and Panasonic also required their repair technicians to return the bad boards to them whereupon they would refurbish them, fully test them, and return them to inventory. When the supply of new boards was exhausted they would then utilize the factory refurbished boards for warranty repairs. They even charged a Core Charge on the replacement boards to ensure that all bad boards were returned to them for refurbishment. It was a simple but brilliant program.

Im in a similar boat and wanted to see people's advice?

About a week ago in a lightening storm we had a power surge. My plasma stopped working. After a few days I ordered an LG OLEDC8.

Today suddenly my GT50 came on again, and I am not sure I can return the TV although I might be able to sell the LG.

Has anyone had experience comparing these two? Should I expect to see any kind of upgrade in PQ on the OLEDC8? I did love my GT50...

I think you should get a big jump in PQ with the C8. I upgraded my GT50 to the LG B6 about a year ago and have no regrets. The picture quality is insanely good on the OLED.

I agree with this.

Motion is likely better on the gt50 but my b7 oled is a huge upgrade in pq otherwise.

Sadly, we also had a lightning strike a few weeks ago. Our TC-P50GT50 seemed to be fine, then one of our HDMI ports stopped working, so we switched to another port and that worked for a while. They all finally went out a couple of days ago. The picture is still fine.

I am able to take the TV apart and remove the "input" board (TNPH0988UC) for repair, but I'd rather not send in ALL the boards if I don't have to. I tried to find information on running a diagnostic test in service mode, but couldn't get past the service main menu. Shouldn't that tell me if there are other problems? Can anyone provide the instructions or a link to run the test here?

Thanks!

Last Saturday evening my trusty old 50GT50 started buzzing very loudly while we were watching it.

It's always been virtually silent since day one (as i always stated in the buzzing thread below, prolly in this one too LOL).

But i was able to fix the cause of the buzzing simply by removing the rear cover and tightening the SC Board's screws and i'm so happy the TV is silent once again. I was afraid it might be terminal, but we've been watching it morning and night for the past 4 days and it's still silent so i'm claiming victory

I posted about it here:

https://www.avsforum.com/forum/167-p...l#post57967794

Now that this has happened to me, and knowing that there are owners in that GT50 buzzing thread with buzzing TVs maybe everybody should remove their rear covers and snug all the board screws down (might quiet down the ones that buzz, and might prevent quiet ones from developing a buzz down the road). I'm gonna cross-post this while i'm at it.

Unhappy Not sure what is going on

Something weird is going on. At first I thought it was my Roku Ultra having a problem. I could use the Roku remote to turn off the tv. And adjust the volume. It stopped doing it. The Roku is connected through a Sony CT660 Sound bar.
It was also set so pushing a button on the Roku remote turned the tv on or if already on would switch to that hdmi port on the sound bar. That no longer works. Using my Channel Master dvr+ remote to turn the volume up Speakers Off
Flashes on the tv. Before it worked. Repairing the Roku remote I can adjust the volume but not turn off the tv. Turning on the tv now, the sound bar no longer turns on. I checked all the hdmi settings on the sound bar and they are on. Back to using 3 remotes. Any thoughts would be appreciated.

Edit: now everything works.
