First check the power supply or swap another.
connect only power 20 or 24 connect and test power on. no off? (no video because no power to cpu by 4 pin or 6 pin connector)
plug 4 pin connector and test power on. if on and off check cpu power section (mosfets) if burned one pls remove ... you can test short by touch the mosfet by finger (burning heat)

U may have to follow the following steps to detect the exact problem
1) Check the power cable convectivty from UPS to SMPS box
if this is OK then check the Fan of SMPS box and POWER LED of the cabinet, if Fan runs, and power LED lights, then u might have to check the Display. If display is not there then it might be the RAM problem
2) if u find all the proper cable conncectivity, then u need check the LED on mother board. but take this step if it is assemble system or if u have hardware knoledge or else contat the system vendor

Possible solution - This happened to me and my battery was dead in my key fob and also I needed an ignition switch because a piece on it was broken which therefore wouldn't turn to start the engine.

I have a Bosch SHU9955US/14 (Integra) dishwasher. There is currently a 0 with and asterisk showing on the display and the unit will not run.

Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.

Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Touchpad If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

Epson PowerLite 410W projector (used for a smart board in a classroom) won't project anything or even turn on. Power button (maybe lamp indicator light? I don't really know anything about this...)...


It seems you assume that it is not an overheating problem.
The problem is, the bulb gets really, really hot when using the projector. It doesn't matter whether it has been there without any usage. As you switch it on, it will start to get hot.
But the lamp or other parts of the projector should not get too hot. To control the temperature, air is moved through the projector with the help of fans. Air enters through air filters and move through the projector absorbing heat from hot parts. This prevents these parts from getting overheated.
But what if air doesn't flow freely? Then the parts CAN get overheated.
First, switch on the projector and check whether you can hear the fans working.
Next, switch off the projector and remove power cable.
After about 30 minutes, remove the cover and check whether the air filters are blocked. If they are, clean them with a small brush.
This would probably solve your problem.

It's probably your logic board. One thing you can try that may help you out is to take out the battery (if you can) and press and hold the power button for 10 seconds. If it's a capacitor problem on the board that should discharge it. If that doesn't work then you should probably try to turn on the computer while holding CMD + Option + P + R to reset the PRAM. If that doesn't work then you're probably going to have to seek professional help.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

My Power Shot SX130 IS wont turn on... I dont know why, yesterday was working and all the sudden today I tried to Power On and doesn't do anything. I changed the batteries .... HELP!



Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

My Belkin F5D8236-4 v3 Router won't turn on. We had a storm last night and the power went out but the router won't turn on. I have tried to plug it into different outlets to see if that would work...


Try resetting the router. There should be a little hole somewhere on it with a button inside that you can press with a paperclip. Try holding that button down while you unplug then plug the router in while holding it (if possible). If that doesn't work, I'd suspect the storm might've damaged the router somehow. Was it plugged into a surge protector, and/or have you noticed any other issues with anything else that was turned on at the time?

When I turn on my set, light turns green, then after 30 seconds turns red won't come on


Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.
