Re: monitor isnt showing any power

I would suspect it needs to have electronic troubleshooting done in the power supply section to find and replace the defective components. Is it possible the capacitor is in backwards?

Monitor wont turn on help

Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.

Dell E173FP power led orange/flashing failure returns

First, you can get the service manual here:
If the transistors failed again, yes the 0.22uf (part of tuned circuits for the inverter transformer oscillator circuits) changed value, the frequency will be off and causes over heat on the transistors due to too much current draw, You can also have bad inverter transformer, you can check the DC Ohm value but if it has one short turn, it will not show up on DC Ohm test, you have to use ringer testing (I use SENCORE LC75).

Dell monitor e17s fbp.. wont turn on

Flashing power LED light means you may have shorted (Emitter to Collector) out transistors (c5707) or bad fuse (fuse has high resistance) PF751. Those are what you need to check. see pictures here:

Post back what what you find so we can guide you further.

It sometimes takes too long to turn on, and lately it wont turn on t al. the led flashes green for 10 minutes untill it shows image and it started not turning on or showing any image

your power supply may need repair. open the back of it. look for capacitors that are leakingo or crowned. or you can take it to have a shop reepair it.

My Lg Monitor wont show screen (Power Button Flashing)

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

BenQ FP591 15" monitor decides to die

Strange that both should show the same symptoms don't you think? Have you changed anything computer wise? Graphics card or resolution? Screeching noise is a puzzle too. How are they powered - internally or via a separate power supply?

Monitor flashes image for split second then goes blank but green LED flashes as well

while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
