No,don't buy plasma tvs any tvs make or tvs brand.Don't buy any kind of tvs using plasma gas as for plasma screen panel as a power sourced if u play major hours of gaming on the plasma tvs,u will still have thermal expansion problems but less.Plasma tvs still have major problems,with screen BURN IN problems though.

Power light blinks red


Hello, If you can turn it back on with the s momentary key or power button:
When it shuts off, do you need to push the power button once or twice to get it back on? Also, does anything else about the picture or sound change as it warms up?
If once, then the controller is shutting the TV down either as a result of a (thermally induced) fault in the controller or it sensing some other problem. Monitoring the voltage on the relay coil (assuming these is one) could help determine what is happening. The controller thinks it is in charge.
If twice, then the power supply is shutting down as the controller still thinks it is on and you are resetting it. A couple of possibilities here would be low voltage or high voltage regulation error (excessive high voltage is sensed and causes shutdown to prevent dangerous X-ray emission). A partially dried up main filter capacitor could also cause a shutdown but there might be other symptoms like hum bars in the picture just before this happened. Clipping a good capacitor across the suspect (with power off!) would confirm or eliminate this possibility.
If it uses a pull-knob (or other hard on/off switch), then this may be like pulling the plug and would reset any abnormal condition.

I think you have a fault on the line output stage either dry solder joints or a fault with components on the line output stage or a faulty line output transformer. If you can check this for yourself otherwise find a competant technician. Hope this helps.
