I had the same problem and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

What happens when you trun on the tv and its cut off


Many circuits today have safty features.
If it's turning itself right back off even with the manual on button it may be a self protection against a short. Don't force it and check the outlet you have it plugged into for ground faults.

My Aquos TV turned its self off and now it wont turn turn back on.


Turned off by itself means overheated in the circuits. If it is condensation, leave the standby on for a few weeks. Try using it to see if it will turn on for a short time.

Our TV keeps shutting it self off intermittenly. Sometimes it will stay on for hours, other times it shuts itself off every few min then will run again for hours. We are selling the TV, but would like to...


My Samsung big screen showed the same symptoms. It ended up being two $5 resisters that burned out a very short time after purchase. My extended warranty took care of it but it took several service calls and the end solution was to replace the entire light engine.

Most of the time heat is the cause for shut down. Check the vents which allow air to circulate thru the set, also be sure the fan is working.

The first thing a repair man will do is replace the bulb. If you can do it yourself you can save some $$.

My advice is to find a good TV guy. One who's been around for a while. Sorry couldn't be more help. Good Luck!

Theres a short between the start-up processor signal on the interface board and power supply. It keeps sending the same start-byte over and over again to the power board. This could also be a DC high voltage shutdown on the power board its self. Now the tv is in protection mode to prevent further damage. Get it serviced at your local repair center. If its under warranty take it back.

What does it mean when my plasma tv turns off by its self? its a panasonic viera plasma tv have had for bout two years


Basically when it turn itself OFF automatically all the time, the TV goes into "Protection Mode". This happens when there is a damaged circuit board inside the need to be replace and turn itself OFF to protect the other ones from being damaged.

A TV service tech will have to look at it to find out which boards need to be replace. There are about 7 different boards in your TV that would cause this problem.
