That sounds very much like overheating...but if the fan is still running after the power off, it may be the projection light that needs replacing.  I'm familiar with this because of scholl projectors!:)  They can be a pain---especially replacing the light!  Good luck!
And since the fan is still running, I would cross that off my list as the problem!:)

    You said that picture comes on for 2-4 minutes, correct?  That may mean a bad connection with the light.  On second thought, it could be the loose connection with projector to light.  Try that first before changing the light bulb altogether!

    Sorry k, I may be wrong...this is not actually my area of expertise...I was spearking  from way way past experience.  This could be a whole new problem I 've never encountered.  It just sounded similar, that's all.

It probably has a fault.But try this.Disconnect all speakers and inputs and try again.If that works reconnect the speakers A PAIR AT a Time.That should lead to the fault.If that still shuts down.

the set is going into protection mode. This is caused when ever one of the many sections of the tv has a shorted circuit. The increase in current is detected by the protection circuit and it flies into action by turning OFF the ON relay.

Most often, but not always, it is either the high voltage section or one of the deflection amplifiers. But can be the power supply, the audio amplifier or voltage regulators, etc.

My air handler keeps trying to blow but keeps stopping the outside unit is working fine, it is an Amana unit.

The most likely things, in order, are:
1) There is too much dirt, dust or lint clogging the squirrel cage fan, slowing it down and causing the motor to overheat and shut off.
2) The motor is clogged with dust or dirt and is overheating and shutting off.
or 3) the ductwork is clogged, causing the motor to overheat and shut off.
God bless your efforts.

I have a Infocus in1503. It shuts down after 10 to 30 minutes. When it does shut down there is no lights. In fact the power light goes off as well.

I seemed to have had the exact same problem... I had placed the projector on top of a small book (to raise the unit), however, did not rest the feet of the projection unit on the book and it overheated and turned off, as a result. (The bottom of the unit was making direct contact with the book which caused it to overheat since not any air was passing through between the two)

After letting it cool for a while and powering it up -- it would usually power off completely for about 15 minutes. After a little thinking, I thought it may be the lamp/bulb and waited a couple of years and bought one online that arrived yesterday.

I installed the new lamp/bulb this morning and it did the same thing. It powered down about a half hour later. Bummer.

I reset the machine to factory defaults and checked to see if it had the 1.03 firmware... It did

Then went through the settings in the setup area and turned off the 'prevent pic screen saver'... Reset the 'lamp hours'

I doubled checked the lamp/bulb installation... Turned it back on -- same thing -- it shut off after about 15 minutes or so... Then unplugged the unit and turned it over and took out the 4 or 5 chassis screws and loosened and took off the side panels and blew onto the fans and circuit board areas and gently pounded the sides to shake anything that shouldn't be there loose and put it back together.

i powered it back on and now it's been working for about 2 hours and 16 minutes!

good luck!

When I plug the unit into power, the CPU fan runs very fast but no boot, and then when I press power on the fan slows down and the PC boots normally. It shuts down in about 30 minutes with no sign of...

Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

Heater turns on and heats 2-3 degress then the service heater light comes on.After about 1 minute the heater fires back up and the light goes out and it repeats this cycle until it up to set temp.

Your "bypass valve" may be wide open, which causes the heater to overheat and shut down till it cools off. Just after the filter there is a pipe, then a valve, then another pipe.Close the valve at least 1/2 way (if not more). This will force water through the heater and keep it from overheating.

My xbox has 2 red lights it keeps overheating but the heat sinks dnt get hot

Wrap it in a couple of towels and let it run, 10-15 minutes, it will overheat and shut down and the three red lights will be flashing, then turn it off, let it cool, 15-30 minutes, turn it back on and bam, it should work, granted its not a permanent thing but it will work from a week-month, from then on the red ring of death will appear when it shuts down instead of the 2 lights, and you can either fix it yourself, do the towel trick again, or just send it to Microsoft if the warranty is still intact. trust me it works.

Is the unit free of dust and debris from dust? If its overheating there are may factors that play in this

1. fan spinning but not enought RPM rotations per min ( not fast enough)
2. room temp
3. dust

other then that some capictors must have exploded inside withc will cause a overheat.

Btw, I’m available to help over the phone in case u need at

Fist, It doesnt overheat when the battery gets low, it just powers off or goes into standby.

Why do you think it over heated?

Try this first. Remove the battery and unplug it for about 2 minutes, re-insert them amnd try to power it on.

What does it do? Any beeps or flashing lights? What color are they?

Viewsonic PJ556d shuts down after 30-60 seconds

My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.

Brand new right out of box Everstar MPK-10CR-1 portable 10,000 BTU's

It sounds to me like it is overheating. Make sure that all of the literature that came with the unit is accounted for. Many times the manual or instructions are blocking the exhaust causing it to overheat. If this is not the problem then I would suggest exchanging it for a new one. It may be a manufacturer defect.
