Try plugging the power cable out for the night. If it doesn't solve it there's probably a problem with the power supply that needs professional care. Good luck

SOURCE: Projection TV keeps shutting down

I just took my Mitsubishi WS-65315 65" in to be repaired for the same problem and was told that it needed a new main circuit board part number 930b899005 as was told they wanted to charge me $1100.00. So I told them not to do the repair and picked up my tv and found that same part at Sears parts for only $225.00. Some of these TV repair places are theifs.

If the picture is playing fine and you notice that the background is getting more and more red, until it is too red and the set shuts down, it could be that the red screen control is set just a bit too high. If this is the case, you can probably correct this yourself. If you are watching a perfect picture and then it suddenly flashes a very bright red, with thin red lines in the pictureand then shuts down, it usually means that the red picture tube has developed a short in it, between the cathode and heater. A good tech might be able to remove the short by arcing, but if the short persists then the red tube will have to be replaced. Either way, this is something that should only be done by a qualified tech.

Samsung tv is shutting off all the time.


Do you have enough air flow to cool it?
It may be overheating....add a fan blowing into it and see if that keeps it on.If it does put a strong small computer fan in somewhere to keep it cool.

Samsung HC-P4752W power and/or convergence problems


Sounds like you soldered two of the convergence pins together by accident. If its shorted the TV will shut down.

Having an issue with a Samsung HCP4752W rear projection hdtv...


if its on for that long its probably not a main capacitor issue a blown capacitor of that size would
have some distortion in its shape look for bulging at the top or bottom or fluid leaks at the base
a good capacitor looks like a small tin can
from the sound of it your problem is elsewhere if the picture is the picture is good then it may be a regulator or power transistor if the picture is distorted then its in your convergence circuit.
