SOURCE: the tv has no picture but sound can be heard. how

Try connecting a different device to the TV and check. You may also try changing the cable to connect the device to the TV and check. If the issue persists, try resetting the TV to the factory settings, then try power reset. To power reset the TV, please disconnect the power cord for a short period of time (approximately 1 minute). Then, reconnect the power cord and power on the TV. If the issue still persists, then service may be required.

SOURCE: no picture, just sound on my 50 inch plasma tv

Does it show a Menu at least? If it does then just switch through the INPUT until you see a picture. Cables most likely to be Video 1, 2 or 3. Video games "LINE", or HDMI..of course "HDMI".

Your remote should have an "INPUT" button.

SOURCE: I have a 2 year old 50 inch samsung plasma tv -

I don't know your set but the way it failed is noteworthy and possibly revealing.
Plasma sets have a little in common with the sets of 30 years ago; they use phosphors to convert electrons into light and the electrons are accelerated with a high voltage.
Loss of the video first indicates the high voltage section (or separate supply using input from a main supply) failed in a way causing the main supply to fail with the loss of audio and complete death.
If it was my set; I would pull the AC plug, allow the set to remain overnight to allow any residual voltage to decay, remove the back, look for a separate assembly the seems related to the AC cord coming in. This should be the main power supply and will have a primary fuse which is likely blown. If it isn't soldered in, replace it. If it blows again, you will need a tech to proceed. The second failure means the high voltage section (or separate supply) has a component failed that is causing the main supply to fail or at least overload so replacing it again isn't logical or productive. If it doesn't blow, you will probably only have audio and a separate fuse in the high voltage section has blown and protected the main supply from damage. It isn't likely that replacing the supply (or supplies) is a straightforward DIY project and there is a slim chance even if you did, that the plasma display is faulty and that the failure would repeat itself.
Because of the problems with shipping a set of this size unless you have retained the original packing material means you will need on-site service and it will be expensive.
It's a pity, but a fact, that our much more complex sets are just not as reliable (at least yet) than the mature designs of the earlier conventional TVs.

They only sell circuit boards so unless you have the skill and equipment to locate where the problem is have a shop look and get an estimate for repair.

Tv keeps turning on and off

You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.
