Try to make a "clear CMOS". There should be a 3 pin slot on the motherboard. Remove the jumper from the first 2 pins and put it to the other 2. The middle pin will be always occupied.
If not, try to change the power source and see if it does the same thing. If so, then you have to change the motherboard.
If you need further assistance, just leave a comment.

THE MONITORES POWER LIGHT KEEPS BLINKING AND THE MONITOR WON'T WORK AND STAYS BLACK


It has shorted out transistors in the inverter circuits, also look for cold solder joints, fuse.

If you are going to DIY and have proper tools and know safety precaution then please read on:
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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Monitor is on but will not display anything


Check to see if the back light inverter circuits has blown fuse and if it is getting the 12~18vdc from the power supply section.

Monitor cycles like circuit breaker cycling.


Check the caps in the power supply with leaking/bulging top.

Monitor just went off. no power light. changed fuse but monitor is completely dead


possibly a power surge killed the main board in the LCD. if the fuse was blown i would suspect a power surge. you could replace the circuit board. either that died or the power supply died- depending on if it has internal or external power supply that might be blown as well.

i would take it to a professional LCD/ LAPTOP repair person. they should be-able to test it and let you know what needs to be replaced

Plug it in with no input connected,press the


I suggest you don't.
There are no user friendly replaceable parts in there.
There May be an inline fuse in the AC circuit, but it's probably a circuit breaker. (Closest thing to a user friendly part, that you'll find)

I suggest you take it to a 'Mom & Pop' computer shop, and see if they will check for a blown fuse inside. The small qualified shops like these, have real computer techs, and not 'Geeks are Us'.
Plus they're cheaper.

If it isn't something simple like a blown fuse, or bad circuit breaker, it's probably the power board.
(Usually the front cover comes off, from loosening it on the backside)

The reasoning for dissuading you from opening the monitor, is that there are Electrolytic Capacitors inside.
They are designed to hold a charge for weeks, sometimes months.
Should you touch the terminals making a circuit, or touch the circuit they're in, and complete a circuit, they could release their charge to you!

This can easily result in a bad shock, or 'Put X's in your eyes'.

VX924 Blown Fuse


What are the symptoms? How do you know the fuse was blown on the monitor you bought? The fuse on vx924 is soldered onto the circuit board. If you have any symptoms that require power its probably not the fuse. The back lighting on this unit has a problem. Three 25v 470uf caps on the circuit board are underrated and have a tendency to go bad. Replace them with 35v 470uf caps.
