Shuts off without warning what the cause - Panasonic PT-50LC13 50" Rear Projection HDTV

The warning light will keep coming on until you deal with the cause. So you either fix the problem or have the warning continue to display and potentially have another problem develop which will stop you starting the car.

When does it shut off, what driving conditions, hot engine or in between or cold engine.

Is Windows crashing or is it just shutting down without warning? If it is without warning, then I would suspect a failing power supply. May want to look at getting a replacement power supply.

Causes:

1. Overheat

Most cases this is caused by a over heat where the system fan gets blocked or there is not enought air flow, this can damage the system cpu.

Other known causes

AC/ adapter needs to be replaced some case were found that the ac adapter would be the cause as well it would be something to have checked out.

Now if the system shuts off without the ac adapter and its running on the battery as well you might want to look at the overheat issue.

try spraying all of your door latches with w-d40. This worked on my van and it's been 2 yrs. now without another ding.

If the PC doesnt show the shutting down dialogue, then hardware proble if it does then its a software problem. Try to replace the powersupply, abnormal voltage sometimes causes this problem, memory and motherboard errors can cause your PC hangs up or blue screen but will not shut off.

Sometimes when you add a new device to your computer, you computer will have a driver conflict and just reboot or shut off. If nothing was introduced to your computer here lateley then it may want to run Windows updates.

Another thing that may cause thing like this to occur is if your CPU fan is not functioning properly. The computer will automatically shut off because of overheating. If you can, unplug everything from your computer, open it and with a can of air, blow it clean and look at all the cooling fans.

With the DVR up and operating well I would lift up one corner about 1/2 inch and drop it to see if that causes it to malfunction. If it does, then you likely have one or more bad solder connections inside that need repair. If no change is noted, then it could possibly be defective capacitors or a voltage regulator going bad on you. There is also a possibility that it could be a worn recepticle the unit is plugged into, as a power interruption may be all it needs to reboot.
