SOURCE: monitor

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.

I found a hp 2509 b computer monitor and I can't get it to power on can it be fixed?


Take it to a TV technician in your area. (If there are any left)
Switch mode power supply probably has a blown internal fuse or bad or leaky electrolytic capacitors.

Iiyama E2607WS just stopped working - completely dead - internal fuse OK


In most cases there are one or two capacitors in the power supply that open, and in some situations they have a bulge at the top making it easier to spot.

My ASUS VH232H wont turn on, it was working just fine, I tried another power cord that I know is ok & still no power


Chances are the internal power supply has gone bad :^(
If you are capable, you might want to open the monitor and see if there is a fuse and if it is bad (open). If there is a fuse, chances are it is soldered in so ..... you would need soldering skills to replace. You would also need a ohm meter (multi-meter) to test the fuse. Should have zero resistance. High resistance will indicate an open fuse.

Best of luck, Jim

Picture dissappeared suddenly. Power Fuse ok but


Faulty component in power supply or line drive circuits. Take to repair shop or find a second hand one, CRT monitors can be had for free or very cheap now.

Monitor switches on ok, but; after a short period; switches off.


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Hi I have an Acer AL1916 that is not powering up, there is no light on the switch, is there anything I can do, like fuses to check etc? Regards Alan


Sorry no fuses that can be changed. Often it is just the power supply going on the fritz, take it in for repair, due to the cost of monitors repairs are usually very reasonable, as long as you find, a place that specializes in Monitor repair, it will be OK. Anyway you can always ask for a "Quote" and decide as to repair or replace,

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.
