The buzzing noise that you were earing came from a bad ballast, and because of the bad ballast your lamp must have got out also, and that is were you are getting the burned smel from and also that is why you are no longer geteting any picture either.

So in this case you would have to replace the ballast board and the lamp on your tv set.

There is a software upgrade to address this particular problem. Contact Panasonic to see if the upgrade can be provided to you free of charge.

Look at the main circuit board do you see any burned resistors?

I had this same problem.

Its Broken And Now Dangerous i would not even try getting it fix. That burnt smell is never a good sign

panasonic is well known for two capacitors 1200pf 2k volts, also it has been known to short out the mosfet transistor, it sounds like you only need to replace the caps.

First there are a few questions. Did You disconnect fly back xformer (black honeycomb looking deal with red large gauge wires)? Did you make sure your solder splash didn't bleed over on causing shorted amplfier(s)? Have you identified what component has went home to ma ma? You should see discoloration on either board, replace blown fuse power board replace damage part(s) and go over real good before applying power.

What does the light on the front of the TV set do. This is a self diagnostic tool. How many times does it blink?

Thats a power supply module going bad. Dont use it until a person with knowledge on TV see that. Or if you feel you can DIY open the back panel to see if there is a toasted or foreign object near the power supply area. Its located when you follow the main plug going into the back panel of your TV. Look for a dying Fuse too. And watch out for Capacitor that has still current, you may electicuted with that component. That parts its only for qualified servicemen area only.
