Story so far: Was given a PL32, - the one with the endemically bad
power adapter, - without a power adapter.

Bought a new one to test the TV.

Plugged it in and ac plug shorted relatively badly when put in wall
socket. TV apparently dead.

Unplugged power adapter from TV and adapter starts to glow green
properly on power light. Plugged it in to TV again and green light
goes out. Unplugged from power.

Tried plugging power cord into wall again and shorts with large spark
again

Does anyone know whether this TV is terminal or can conceivably be
repaired at any sort of reasonable cost? There seems to be something
called a Protron PLTV-3250 Power Supply FSP194-3F01 which costs $80.
It cant possibly be worth spending that much on a potential repair
part can it? The part (if this is what it is!) describes itself as
being "Air cooled, no fan required, operating temperature 0-55°C.
Built-in short circuit, over voltage, and over current protection"
