The backlights are not on! Hold a flashlight towards the screen, do you see a faint picture?

SOURCE: tv screen went black and no sound

Look at the power supply first; look for burnt parts, bad capacitors, etc.

Please post back what you find. It sounds like at least you do have the 5V standby power supply working but the main supply is not getting the 'ON' command from the main board, or the power supply is gettin ght e 'ON' signal but failed to turn on.

SOURCE: Sony kdl-26m4000 LCD TV. While

The processor of the tv locks up because it suddenly becomes incapable of correctly processing the signal data - it crashes.
Since this is an intermittent problem that appears when a big spike in power is required from the source that means that the problem is caused by a dip in the voltage powering the processor - the power source has aged and it's no longer capable of delivering a steady supply.
You must open the tv, locate the power source and refurbish it: start by replacing all capacitors, then check the rectifiers, then the zenner diodes and finally the stabilizers.

SOURCE: 47" plasma 1080p ... screen went black , sound

Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.
