When i turn tv on it immediatly shuts back off

Sounds like corrupted firmware. Contact any service technician. A firmware update is necessary.

you have a component failure. begin checking the on-board fuses. that should lead you to the circuit that failed. most often it is the convergence circuit. 2nd most is a loss of vertical deflection. this is a tube protection circuit that shuts the set off before it destroys the crt's.

I have a big box flat screen tv that after you cut it on it cuts back off and then you cannot cut it back on

Either the CRT Drive Board is bad or the CRT is shorted.

Sounds to me that ist is more of a charger issue. Try to borrow another charger and see if that works or not.

Unplug the power from the power outlet and let it sit for a few minutes. Then plug it back and it should work normally.

Overvoltage protection circuit kicking in. You have a problem in the Hivoltage section somewhere.

HI, I haHe a Fujitsu Plasma HDTV Model PDS4233. The TV won't power ON, When i turn on the master power button the light starts flashing a red light repeatedly. I also observed that the Fans power up for about three seconds immediatly after i press the master power button, after the three seconds the fans shut OFF and the light continues to blink.. I haven't observed the light to see if there is a pattern with the blinking..

check your smps in your tv or Ic is collapsed

you have a bad CRT causing the set to shut down. after the CRT has cooled down the computer finds all value to be ok then comes back on....
