TV sparks inside case

My TV sparks inside it's case. I took it apart and they seem to be coming from the power supply.
I have replaced the fuse many times on this thing - it doesn't burn out with this problem.
Do I replace the power supply? Where would you recommend to find one.

It's very hard to exactly diagnose your problem exactly without being there. I'd say you have a power supply issue inside the keyboard. Maybe a shorted filter or diodes. If you have replaced the AC adapter, be sure that the polarity, voltage and current rating is correct.

I have 47" LG LCD TV (47LD450-AU) and when I try to turn it on the red LED just blinks slowly. So I took it apart to check the power supply panel (P/N: EAX61289601/12) and it seems fine, at least all the...

These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

I assume it was the power supply that you replaced? It is very likely that a fusible device on another board has gone open circuit to protect any damage due to the initial problem. Again I assume you have a plasma TV in which case there will probably be a problem on the Y or Z sustain boards which may also need to be replaced as this may have been the reason for the other board to burn up

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

TV Sparks inside case

I think I would turn it off and unplug it. You could get an estimate on reparing the power supply cord or whatever the problem is or the TV maybe ready for replacement.

Are there any fans moving in the case? As in, are you getting any power? If no fans are moving, it's possible it's:
1) the power supply (PSU)
2) your 'jumper' from the power button to the motherboard has come unplugged
3) you're grounding out somewhere

One cheap-o way of testing a power supply is:

Turn your power supply off.
Unplug your power supply.
Get a paper clip.
Bend it into a U-shape with the ends close together.
Put one end of the paper clip into *the* green wire in the plug of the PSU.
Put the other end of the paper clip into a black wire of the PSU.
Plug in the PSU.
Turn on the PSU.
If the fan runs in the PSU, it's safe to say this PSU is in working order.

If the the power supply was fine, but when you hit the power button and it no fans inside the case move, check the plug from the case to ther "power on" jumper on the motherboard. if that's correct, I'd suggest removing the entire motherboard from the case and setting it onto a phonebook and see if it'll turn on there.

If fans are moving when you hit the power button, but no beeps, fans turn back off after a moment, ect:
1) Motheboard is bad
2) Processor is bad

These are the situations that are most likely.

Computers are picky about being played around in. You can look at them wrong and they'll stop working. Sometimes it's as simple as pulling them apart and putting back together again to make them work... at least in my experience. I wish you the best of luck.
