    You have either a bad Power Control Assembly, a bad Power Control Board, a blown fuse, or a loose connection inside the monitor? We can trouble shot several ways. Do you have another Monitor?

It is possible that the main board has some dry solderring joints. You will need to open the main board and check with a good lighting, a magnifying glass for finding the fault. Look for faulty connectors.Push them in and keep all connectors tight.
When the set cuts off check to see after disconnection of power if any of the components are heating up. If so check and see the reason ,may be drypoints must be checked on these components.
Check the voltage at the power on and off condition which can be a good indicator to the fault area.

Hope my advice helps.

Car froze one cold night, plugged it in a day later, tried to start it after it was plugged in for an hour, started for 5 seconds then died, started again, backfired then died, Tried boosting it, turns...

It will be good to have some hot water poured on to the radiator and engine without any on the electicals . If possible you can remove the plugs and clean and heat them before it is set back.
Have the battery charged before this so as to have a good cranking.
The cold engine needs a good spark to come to life. so try this out.

Power light suddenly went out. If I unplug, wait, and plug back in, the power light comes on momentarily, then goes out again.

Same problem here with IP4000. Power light comes on for a second and then dies. Let me know if you get a resolution.

My viewsonic mo9nitor says analog not digital on

To clarify, you know that analog is referring to the VGA 15 pin video input, and digital is referring to the DVI video input, right? You can't have the digital video unless you use the DVI input, which requires a DVI output from your computer (and a DVI cord of course).
If you already knew this and you mean that it won't switch over to your DVI, then there could be several problems. Most of them being with your DVI signal source (computer). Try booting the PC with ONLY the DVI cord attached between the PC and the monitor. If you have a VGA cord plugged into either, UNPLUG IT FROM BOTH ENDS.

Car dies when driving,check engine light comes on.

There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

Have u checked for spark? U can pull a plug wire off, install a plug in the wire (saves u from taking a plug out), place plug on metal surface, crank engine while someone watches for a spark. If no spark check coil and ignitor (inside distributor). If u have spark check to see if u have gas making it to plugs. Crank engine over (no more than 10 seconds, give it a 10 second rest, try again for 10 sec. etc, ) After doing this for several minutes, pull a plug and check it--it should be wet from gas. If the plug is dry, u aren't getting gas (change fuel filter, check fuel pump). countrycurt0
