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. Thanks.

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.
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.

only fuse I know is near back of tv inside power section right next to the power cord input ... my first thought tho is damaged capacitors inside same area ... good luck getting it apart ... I took mine apart but difficult to figure how
Facing the back of television, if it occured while putting top right screw, that is because, you screw touched power module casing and the fuse inside the TV is gone. All you need to do is goto radio shack or any local store and get a replacement fuse (250v x 5 Amp) and replace it. It may cost you less than 2 bucks.
TV powers off and never turns on.
May even power in that room or house may have been tripped.
lay the TV face down on the floor.
Remove the screwes ( may be 10 - 15 screws)
Remove rear casing of the TV. It is single casing covering entire rear face of the TV.
Fuse is visibe as soon as you remove the casing.
Replace the fuse.
Put the casing back.
Start enjoying the TV.
Do not use longer screwes to mount monitor brackets on TV casing.
dude i dont know if this will help you or not but the same thing happened to mine and im an electrician, so i took it apart and screwed around with it and everything seemed to be cool so i took it to a tv repair shop and they fixed it and it only cost me $65.00. he told me that the power supply motherboard burned out for good.
