It will not work i switch it on and nothing happens

Remove cable connecting monitor to computer, turn it on. If you see a "NO SIGNAL" note, your monitor is ok and the problem is the graphic card of your computer. If you've recently removed and reconnected the monitor, might be a bent pin of cable input.
If Monitor is dead when you turn it on disconnected, it's defective and you should repair it

Will not switch on, no green light totally dead?


These units are known for having issues with the internal power supply board. There are parts called capacitors that fail due to heat buildup in the monitor case. When they die the power supply stops working and you get a dead monitor just like you have. If you can solder then you should be able to repair your unit. We have a free step by step repair guide posted on our web site at: The repair should take less than 20 minutes to do and cost less than $15 for parts.

I hope this helps, if so please rate our solution.

Monitor shows no power light and won't switch on

There probably will be an internal fuse but a warning even when disconnected from the mains your monitor can give you a bad shock and the fuse has probably gone due to another failed component

my advice if unsure let a qualified electrician test it

Power problem

for the quickest fix, you should try a new power supply cord and see if its just a bad cable. almost any monitor cable (dell brand) should work. if you do not see any of the lights on the monitor light up then you have an internal problem and it will be costly to repair. probably better of buying a new monitor.

Dead monitor dell e173fp lcd monitor

This could be either down to an internal fuse blown or the main board or the capacitor on the power supply could be faulty.

Dell E197FP LCD Monitor won't turn on completely dead

could be dead, but check to ensure that you are using the monitor ONLY, not TV tuner device. as a standalone, not hooked to cpu if there is no power light when plugged in assume your buying a new monitor.

Monitor is black, the blue lcd at the switch does not lite when switch is turned on. The internal fuse is ok. I tried to find a schmatic on I could check the power supply, no luck.

I have the same problem. Took it apart for troubleshooting. Found that if I disconnect the ribbon cable between the display driver circuit board and the LCD panel, I can turn on power and it will stay on. I can turn it on and off with the power switch. With the LCD panel cable connected, Power turns on (power light blinks) then apparently a fault with the LCD panel causes the power supply to shutdown. At this point the power switch does nothing. Now the big question is "Can you purchase a LCD panel?" If so, it probably costs more than a new monitor. Hope this was helpful.

Monitor won't power on

PF747 has internal switch-mode power supply. Old LCD monitors have external low voltage (12VDC) power supply which can easily be replaced by any brand provided the voltage and current is the same. On your monitor, th epower supply module is built inside the unit. When you say that the LED is flashing, this means two things, 1. The power supply is attempting to start, but the load (or current) is above its limit and it automatically switch off, then tries to start again and so on. This can be a problem with the load (minitor intelligence or the mainboard, hv supply for the flourecent back supply) 2. It can be that the power supply module is defective In any any case, the only way to find out is to disconnect the load from the internal power supply (the monitor have to be opened), and measure the voltage at the terminal. In many devices the output will be 12 volts and in some cases there will be also 5volds supply. If there are correct voltage present, then the supply is OK and most probably the mainboard or the HV supply is defective. If there are no voltage present, then the power supply module is defective. You can either fix this module, replace with exact new module or if you have a spare external powersupply, you can use this to provide the power to the internal circuit. The last option is recommended only if you have experience in electronics repair. If you cannot do the repair yourself and will cost USD200, buy a new monitor.
