My 42 in plasma gets really hot - Vizio P2 42 in. HD-Ready Plasma Television

I've owned a 42HDX99 since 2007, It's always been warm/hot. Still works/looks Awesome. Plasmas do generally run hotter than
LCD/LED's. Also have a 58" Samsung Plasma ( which I've had to repair ) and a 2009 Toshiba 1080P LCD ( still works great )

You can check the va, vs adjustment, but alot of plasmas does this, my first thought would be the y sus board, it also could be the panel which is not worth fixing, if it is really bad, check voltage and if this isn't out then Y- board is the next thing to check.

Yes,it's normal, a plasma uses a lot of power (over 300W) so it generates a lot of heat - especially the screen.Remember, plasma is an overheated gas so a large screen contains a very large amount of a very hot gas.

This is not really a solution, but read on... I had these symptoms in my 42 inch Hitachi plasma also.When I took it in to get it looked at , I was told that dust was accumulating on and around the cooling fans.He gave it a quick cleaning ( vacuuming I assume) and it worked for a while then started malfunctioning again. Now I'm trying to decide whether to just pitch it or keep cleaning it myself.Hope this helps.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

bought a new power supply / board and had it installed. Has worked for 9 months, but now the screen goes black after it warms up, still gets the sound, just no picture. The tech that replaced the board told me that type of TV get extremely hot and it fry's the components.

there is internal failure inside..

Do u loose picture and audio at the same time and when the led starts to flash on the front of the TV is it a red 5 ? If so there is an oscillating crystal that is getting really hot on the SSB. 27Mhz xtal. if need more specifics ill get the philips replacement part number.and where it is located of the SSB.

I knead the wire for the spikers I losted and is imposibe to get sound on my TV plasma esa 42"
