Where do I put the smoke in?

Just google for instructions on refilling the plasma on a PDP. Really, you should avoid smoke letting on most electronics...

I’d take guess it’s most likely the resistors that have caked up big time or possible a few dozen capacitors as well.

Also coil circuitry can smoke up. What in the blazes have you been doing to it for it to end up this way?

It would help if we know what it is make and model and pictures please because this thread is worthless without pictures.

Well, I make it and will glad to give you some for free. But there is a shipping and handling charge.
