If lights are lighting you supply is working...
Microsoft OS ? if yes,,,Do you get any beeping sounds?
If so the CPU is ok and and you need to define the beep code on boot. It tells you about the hardware there. If error beeps the computer will not start up...
You find this in a computer lingo reference manual of ask a search engine these questions. Since you got this far on line I expect you can see to it to find more info
You need to try a working borrowed monitor.
Sometimes that helps ...

Motherboard is getting 12V, 5,2V from power supply. Probably 5,2V is dead. If you have a friend who will give you a power supply. Put in your computer and you will see that is the problem.

LG E2350 monitor will not start up. Have unplugged and rebooted but still will not start up. 6 months old. Did this 3 weeks ago and a week later started to work.


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where in the power panel board, but you need to open the back cover of the television to enable you to check for the fault also be careful in solving the problem because it contain high voltage, if otherwise the power supply board is dead, you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this help in solving the problem......

My view sonic VX2835wm monitor slowyly but surely started to die. 1st symptom: it would shut off with computer then turn back on with blue screen. 2nd symptom: you had to finally disconnect and reconnect...


From your description you have two or three different problems, power supply/inverter board issue and poor color. The cost to repair will be more than a new monitor, I recommend not going any further with this.

My monitor is unresponsive. Does not power on anymore. Does anyone have any troubleshooting ideas?


If your monitor uses a power supply (the brick that plugs into the wall, and then a smaller cord plugs into the monitor), then it's more likely the power supply that's gone out than the monitor itself.

Find someone with a multimeter to check the output voltage on the power supply. There will be a label on the power supply that says what the DC voltage (VDC) is supposed to be. If the meter shows no voltage when the power supply is plugged into the wall, then you just need a new power supply.

Do not try using another power supply as a substitute unless it is a specific match to your monitor. They vary widely by output voltage, etc. and using the wrong one could fry your monitor.

Hope that's helpful.

Microtek 715c power supply requirements. I found this monitor by the curb and gave it a 17.5 vdc switched power supply. It works quite well except the power light goes blank while asleep and acts like...


SuperWarehouse.com just says it requires anywhere from 110-240 volts AC (which isn't very specific) and uses 48 watts. I don't see anywhere online that lists the DC power output... sorry. If you could get a manual for it that might help.

Monitor looks as if there is no CPU


If the power supply is coming to CPU before activation of CPU then it must be receiving current from UPS. Don't try unplugging, You may get shock. Thank you, Sir.

Replaced my power supply, now keyboard and monitor wont work.


Believe it or not, if you have a floppy drive in your computer, try unplugging it and disconnecting the data ribbon. Many times, damaged floppy drives can short out motherboard functions and even prevent computers from powering up. If that doesn't fix it, then get a usb keyboard and mouse set (wireless would be fine) or borrow some, and see if they work. If they do, then the power outage damaged the PS2 ports.

Power supply dead


dear,

i think u saw the information pasted on the back side of monitor...
dead means that something is wrong inside...
initially, you have to check the power cable and availability of mains in the socket..
if all are fine then we will go inside..

after removing the cover carefully, check the mains fuse that is near the power cable socket where the power plug inserts...
if fuse is fine then check the mains capacitor and then further....
Maybe the problem pin points here and u solve the issue..

goodluck...

hopefully, it will fix the issue so rate it ...

Hp flat screen monitor


It's probably your dc power supply.

Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.

I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.

I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.

DC output 10-17v  3.5A
Nom. V 12v
