I have a panosonic plasma tv when i switch it on it tell me there is a speaker short and then switches it self of model number pdp507xda help

It's the internal circuitry problem. Try muting it and put audio connection to other speakers if it repeats, your TV audio system is internally dying.the audio connections has to be checked and faulty components should be replaced.
1. Speaker short.
Open it up and check the speaker connections. ONLY if you have basic skills working on electronics and don't have a warranty.
2. Sound Volume "Leveler"
Look in your sound option menu for a sound "balancer" option and turn it off.
If this doesn't work disable the sound and invest in that surround sound system (external speakers solution of your choice)

try this.for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the audio circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv starts and turns off. if the tv is connected to externalk speakers then check out without connecting the external speakers and see whether it works.if it works that means tv is perfect.but if tv is having inbuilt speakers that its confirm problem with inter audio circuit of tv.so try connecting external speakers at the back of tv and check out.
