Hello,
All you have to do is to open the back cover of the television, first check for blown fuses, bulged capacitors.
The main cause of this power up problem are bad capacitors on your power if the capacitor is bad.
Now lets talk about the specs, capacitors hold 3 important value:
The capacitance measured in uF(micro farads) (ex. 2200uF), 2. Voltage (ex. 10v), 3. Temperature (ex. 105°C)
Then Check the power supply printed circuit board as well as the projection set up(lamp,colour wheel,etc) to make sure that everything is working okay and isn't damaged. Also check that when the unit is turned on it is getting a voltage reading to the power supply printed circuit board to ensure the unit is either getting power or not getting power.

Hope this help in solving the problem.

My Cerwin vega xls 15s doesn`t work!


Blown circuit. The question is; was it the power supply that blew out or was it the amp? check for fuses and see if they are ok. If they are not, replace them. IF they are then you are going to have to get new amp and or power supply.

do you mean you replaced the power supply of the monitor?. ok, does it the same specification the voltage and amper rating, from the original power supply?. if yes does the power indicator, stay or blinking?.just let me know if this is what you are asking for, so i can give some further solution.

Sounds like you might have a partial power supply failure. Try unplugging the power supply from everything. Ther should be a switch on the back that is red and says something like 115/220 just flip that switch over to 220 and wait 5 minutes then switch it back to 115 and replug everything in and then try it. If it doesn't work then unplug everything again and let it sit for about 30 minutes (this resets the power supply) and reconnect the wires and if that doesn't work try getting a new power supply. In partial PCB (Power Supply Board) failures the problem is that trere isn't enough power going to the system to start up so sometimes resetting the PCB will fix it temporary. You should get a new one anyway. that one will fail completely soon. Good luck!

Goldstar 2006 doesn't work at all ,no power


Hello,

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the cooker, it goes straight into the power supply board which then circulates the current into the unit. So if the cooker doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

Hello my laptop will not tun on when i slide thepower switch. HELP ME PLASE. PLEASE Thank you VERY MUCH


Check for voltage at the tip of the power connector.
If there's power there, try removing the battery and powering it up.
If that doesn't work, you can try a new power supply, but get a written guarantee that if the unit doesn't work, that you can return it.
If a new power supply doesn't fix the issue, even with a new power supply, then chances are unless you are an electronics technician/technologist, you aren't going to be able to repair the unit yourself.
Most places will want to replace your motherboard - don't use these shops.
Find a place like www.SuperTech-IT.com that does component level repairs and can evaluate and repair the motherboard rather than replacing it.

The LED in my motherboard is on, but if i turn on the switch, their is no response. the power connection is correct. but it doesn't work


Try swapping the power button connection with the reset button connection. Then to turn on your computer you will need to press the reset button. If that works you have a faulty power button. Otherwise try using a different PSU. One that you know works. If that doesn't help the motherboard will have to be replaced.

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.

I have a hp pavilion 513c it wont boot up! the


Hello,

There are only two ways this can go for you.

One- you need a new power supply

OR

Two, you need a new mother board

You can verify the power supply by checking it on another machine

If the power suppy is good

And you do not hear the bios beep- then you are looking at a new motherboard- I would double check the powersupply first- most stores that sell them will let you check before you buy a new powersupply.

E-machine Model D2246 does not power up


E-machines are notorious for having weak power supplies. Although not impossible, it is unlikely the motherboards are damaged.

You may also look online for rebuilt power supplies that are beefed up from the originals.

Be sure you have a good surge suppressor and surge suppression on your phoneline if you use dialup. I also recommend surge suppression on your ethernet connection as well.
