Check all fans On M/board to see if they are working also that your heat sink on CPU is clean no fluff or dirt clogging vanes this could be an overheating problem
Another quick check is to remove side of case if it stays on longer it definitely is overheating

Lg w2234s-bn Monitor Cycling randomly through Light View Modes/Power Button turning It's self on and off.


On and off cycleing could be caused by a bad power supply or a low battery on your remote. Check them both out. Good luck.

TV turns on, then turns it self off about 5 minutes later. Then you must wait awhile to turn it back on. Already checked and there is no sleep timer or any other setting enabled.


I had a similar problem with my Samsung LCD TV. It turned out to be the internal power supply that was the cause of this trouble. When the repairman came out I told him what had been happening and he said "yeah power supply" right away and replaced it (under extended warranty that I usually don't buy) and yay it's working again still 2 years later.

I have a STOP message on the oven display. The user manual refers me to the product description sheet or the electronic programmer description, neither of which I have. The oven is not working at all while...


HI. This is a control fault, that may be corrected by simply shutting down the appropriate circuit breaker for 5 minutes. This will DE-energize the control board. Once the 5 minutes have passed, simply re-introduce power to the unit. If the unit continues to produce the error, this will confirm that the main control board has failed. it should be replaced asap.

When I turn on the power to my pc, the on light blinks once and shuts off. The pc never powers up.


Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes PC
More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.
Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

CPU turns on but turns off within seconds, rarely minutes into self-fix module. Local technician suggested replacing motherboard. Could this be power supply problem or is it the motherboard.


This can actually be a propblem with the power supply , processor or the motherboard already, but to isolate this problem correctly better if you try replacing first the power supply since this problem is usually cause also by a failing power supply...

Dell inspiron 5150 do not come on when the power button pressed


If you remove the battery and disconnect power cord, then hold power button for 20 seconds, then reconnect power cord but do not re-insert battery, and the unit powers on okay, the problem may be your battery. If there is still an intermittent problem, the power connector inside the unit may be loose and need re-soldering, or you could have a bad power supply.

Ran self clean on my oven and it stopped in middle of cleaning cycle


That most likely means there is a fault in the control board. You need to contact the manufacturer or retailer for service.

can you be more specific when describing the computer 'struggling to restart'? Does it beep? Does it take several attempts to restart?
