Panasonic TH-42PX600U The set just quit. It won't turn on. I checked the power cord and it is fine. I took the back off and it appears the two fuses where the power comes in are blown. Ray [email protected]

Question edited for clarity. I doubt your television id 58 FEET (58')

You don't give the model number or what you are trying to sign into? WiFi, Netflix, Cable, Parental Controls?

Of Course there is a fuse at its main power regulator board. but, you must have sound knowledge in electronics, to replace it, especially to Plasma displays. If you wish to get more details, check the site linked here. If you have confidence, follow. http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Check and replace its main power regulator board. Before replacing it, check the fuse, can be located on this board itself.

likely a coil or small transformer in the set is vibrating hard enough to make it squeel, it would have to be located with back off by listening to see where it comes from.

cure would be to replace the entire board it is on or hot glue the part that is causing this to dampen the sound.

If it is coming from the front screen unit that is a more serious issue.

Panasonic plasmas are notorious for their power board problems.

I can't know which one of the few possibilities yours might have, but at the very least it is worth checking against the most common ones(s):

Read the listing, get a multimeter and check the described components for short or open (in case of a fuse) and if it matches then that's the problem and that's the solution.

For in-depth troubleshooting help consider using www.coppelltvrepair.com/diagnose - it's free to ask, but we may not always be able or willing to help and when we do we'll typically put a price on a consultation.

if you have the right tools then you can do it, make sure unplug the tv unit first while replacing the board. then mark or put a label to the connector that you were disconnect not to interchange that can cause of damage to the other board.

I would guess it's the power unit for the TV itself.

If it's still under guarantee I would have thought you should be able to get it replaced.

I am not familar with your exact model but my Panasonic TH-42PX600U 42 in. Plasma uses a generic brand wall mount. The first mount I bought would not fit so I returned it and bought a different brand which worked well. Start shopping your local stores (even walmart has a couple of different types to choose from), carefully open the packaging in case you need to return it and see if it will fit the mounting holes on the back of your TV. If it fits on the back of the TV then you should be good to go.
