Akai plasma 60" picture looks like a lava lamp sound still good

Sounds like a problem with the Z sustain board.
But the fact that you still have sound, it's more likely the Y sustain board.

As for not powering off...Unplug it from the mains and try a reboot.
Does it respond to the remote?

Both the boards should have fuses, so you could check those first.
Be careful though, don't touch anything else as there are high voltages inside.

Hi Laurie, the fuses are probably white in colour and therefore a visual check wont tell you much.
The fuse can be bought at any electronic / electrical whole saler.
You need to check the fuse on the board and if blown replace it with the same values!! NOT a hair clip or kitchen foil !!!!
You will only need a very basic continuity tester for the fuse but a multimeter is a far more useful tool.

As I said earlier, DO NOT go poking around inside. There are high voltages.

If the fuse blows immediately, there is obviously an underlying issue beyond your skills.
Better to buy a replacement board.

I very much doubt it. I think your rear panel is plastic.

Can you give us the model number of the TV?
Which board had the blown fuse?
Can you upload a clear and close picture of the board?

Have you got a multimeter?
