Screen shuts off

How old is the tv set also do you have it plugged up to a power cord? Can you tell me how many times does the light blink thank you.

hi.please you turn system in cooling mod and check compressor.
maybe you must change capacitor compressor.
you send capacity system to me.

Check your wiring connections. A similar thing started happening to me out of the blue. The unit would work fine for a period of time, and then just shut off for no reason, and I couldn't get it to come back on. The next day, it would come on again when I started the car and stay on for a while, only to shut down again. The red light behind the face plate continually flashed, regardless of whether the receiver was working. In my case, there was something off in my red wire connection. The unit would turn on / shut off when I moving the wires on either side of the connection. I redid the connection, secured it with electrical tape, and the problem has not reoccurred. If the red wire is not the problem in your case, try the black and yellow connections. These appear to be the wires that could cause this to happen. I can't explain why the power kept repeating the power on / off cycle, unless the wires were in just the right position to be moved / jostled slightly while driving. Hope this helps.

The only possibilities I see here are either the Plug Holder with Fuse Block which sometimes goes bad and periodically will shut down the unit. The other possibility is that the Electronic Card has gone bad. It over-heats and shuts down power.

Unfortunately it has nothing to do with the power plug.

If you turn it on and it works normally but then shuts down it's activating an internal protection circuitry to prevent damage to your set. It's not an adjustment, it's not something you can fix at home. Sorry to be the bearer of bad news but it will likely require a shop repair.

It is normal for the screen to stay on for a short period of time after you turn off the engine and leave the car. It should shut off after a minute or so.

bright red with lines left to right? would be shorted crt. shutting off would be normal due to high beam current.

i also have the same problem with the flashing green light for a while then a different red light starts blinking on and off around 5 times....and i replaced my burnt bulb with a new one...still no picture.

If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.

Shorted red driver trans shorted red pic tube defective focus/screen block any or all of these stk's on convergence module check the solder joints on convergence module
