Panasonic Plasma TC-P65ST60 - Half screen black

[hurlieburlie]

Hey Everyone:

I am posting to inquire about how I might fix a problem with my Panasonic Plasma TV. The other day, the right half of the screen went black. At first it started with colored lines and now it has fully gone black. It is almost like half the screen it off.

Remove works and there is sound coming out of the TV. I was not able to get into any service menus as I read that if I press -volume and menu 3 times, it would pop up.

I have taken off the back and none of the connectors are loose that I can find.

Attached is a picture of what happened. I am willing to buy a new board if necessary from ebay or something. I have had the TV since 2013.

Thanks for any help you people can provide.

-Colin

You need to press the volume down button on the TV and then press 0 0 0 OR info 3 times. ( So either zero or info button ).

This looks like bad mainboard , sending no signal to the lower C boards.

Ps , there is not much you can do in the service menu to fix this problem. This is hardware related. Either bad panel OR bad mainboard. My guess is the mainboard because the whole screen got black but still shows colours.

What is the main board usually called. I have seen that there are SC Board and SS board. Is the main board just called "Control Board"?

Thanks!

Re: Panasonic Plasma TC-P65ST60 - Half screen black

Its called the A board.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

Any idea where one whould buy a board like that? I looked on ebay. They just have the other boards.

I live in Canada, but willing to buy from anywhere.

I looked on eBay but there are none available. Here is a place in Indiana , USA that I've used before that will repair it.

I would suspect C1 or C2 boards or one of the cof for the panel. if one of the cof ic's is shorted sometimes you can tell by looking at it with a magnifier, also it will run hot compaired to the others, one bad chip could cause the others after it not to function giving half black screen.

Can't we bring up test patterns on this one? That should tell if it's A board or c boards.

btw,hello fellow Albertian

Whats the exact part number on your mainboard? Your mainboard is the board with all the HDMI Connectors. Its located on your right hand side.

You need to find out the part number --> TNPH1045UA #TXN/A1UJUUS ?

unfortunately for the O P you hit it.
might try reseating the ribbons but 99% bad panel.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

15th generation plasma model guide says that it's the lower C boards that have failed and not panel , especially because only 1 side is affected. ( Cut in half ).

The C boards are the small boards on bottom side of the tv. Probably easy to find.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

you should be able to bring up test patterns, do vertical and horizontal flips. I'm thinking if you do a horizontal flip and the right side was visible on the left I'd be inclined to think panel or C board/s for that area.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

This is probably a panel fault. If the failed area ribbon can be detached from the C board and the picture comes back on the rest of the panel it is probably a panel failure. (Be careful with the ribbon and make sure to reattach the heatsink if you do this.)

Re: Panasonic Plasma TC-P65ST60 - Half screen black

Thanks everyone!

I will probably try and buy the C boards. Does each C board correspond to a portion of the screen?

What I mean is that if it is the right side, would it be the C board behind that side that I should try replacing first?

Thanks.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

Yes you need to replace that part and see what happens. Take Toms advice , its not easy to replace.

Did you try the test patterns as TW2005 suggested? You can find them in the service menu.

Re: Panasonic Plasma TC-P65ST60 - Half screen black

So I did the service tests and did a flip from right side to left and that worked.

I could see what was supposed to be on the right side of my TV on the left.

So it looks like it may be the C1 board?

Re: Panasonic Plasma TC-P65ST60 - Half screen black

I think if you're going to roll the dice and try c boards I'd get the c2 as well. It looks like more than 1/3 of the screen and maybe the fault is on the c2 where that red area is, and not passing the data on to the c1.

I hope it is those but being a pessimist I won't be surprised if it's panel, c boards are generally cheap as they're a rare thing to replace.

could get a complete set if you wished. S60 ST60 use the same
