Can you give me some advice on, how to mount a 46in tv above my non working fireplace mantle?

You would have to use a mounting bracket specifically designed for the type of installation you describe and it certainly would have to be fastened into the studs behind the sheetrock. A TV of that size will be heavy to lift and install in the bracket

We would like to mount our 50 inch Sanyo plasma tv above our fireplace. Is there a temperature limit we need to worry about and do compatable wall mounts have the hardware for brick/mortar?

As long as the set is mounted correctly, there should be no real trouble with heat.
The Mounts, are/maybe standard, however it is the fastening that will differ, if stone, brick, concrete then special fixings must be used, apart from that you will be all good.

Panasonic Viera 46" plasma~no sound, no picture

I would use the warranty at Bestbuy at that point. Opening up the TV would most likely void the warranty.

Height of tv

2000m = 2km, which is pretty high, and may cause problems at this altitude, probably something to do with pressure and the plasma gas ignition, I guarantee your fireplace is not this high.

Wall mount for 52in tv ?

Here is a mount rated for your size TV

Also, be VERY careful mounting ANY plasma above a fireplace. Plasma sets are typically convection cooled to avoid the noise of fans. The heat from a fireplace will GREATLY reduce the life of the set. When people I know insist on putting a set above a fireplace I usually insist they install a cooling fan with ducting that will vent fresh air to the set. If you are concerned about the temp of your set simply consult the owners manual for operating temperature and measure the air above the fireplace yourself. typically has good prices on mounts along with amazon. most other places like bestbuy or circuitcity will stick you on the price of the mount because they make their money from accessories. Also, why did your last set die? plasmas are typically rateed for 10+ years, did yours over heat and start to change colors?

Distance over gas fireplace

Both LCD TVs and plasma TVs get hot, though plasma TVs tend to be a bit hotter in my experience. Also, plasma TVs are going out of fashion.

A lot will depend on the construction of your fireplace. If it's brick it should insulate fairly well.

Either way, I would recommend a mounting solution that does not put the back of the TV flush with the wall. Get one that tilts. I would avoid the "arm" style ones as that will put additional strain on the mounting.

Remember to think about how you want to run your power and video cabling as well!

Peel off the black tape?
Is this still covered by warranty?
If one expects help here then one should quit being lazy.
Brand names, model numbers, age, has it had anything spilled in it lately, been moved, and any and ALL other details you can provide!  

But, a possible cause is power supply circuitry, possibly electrolytic capacitors. Remove covers, unsolder, and replace.
Or call a tech.

Plasma flat display

in plasma tvs when the screen is all black the most common fix is your y-sus board. if your tv still turns on ( led in front of tv comes on) and you have all of your voltages coming from the smps board then i would get a new y-sus board.

Just a consumer quesstion.

Heat rises and smoke has particulate matter in it. And heat is the enemy of electronics. So personally, I would not mount any expensive TV over a fireplace. However, if you have nice glass doors covering your fireplace opening, good updraft in your fireplace, and a large mantel that projects out over the opening, you will probably get reasonable life out of your LCD TV.

Loss of the color Red....Possibley others on my plasma

If you are lucky, it could be an open resistor or defective IC. Otherwise, I see a new TV in your future as the Plasma display would cost nearly $5500 for the part alone. If the fireplace is used much, I would not mount a TV above it, especially a plasma set which generates a lot of heat all by itself. If the fireplace is only used occasionally and you want to put the replacement set in the same spot, then I would consider a LCD model instead.
