Stay always black and I heard a blink noise over coils on PCB


The capacitors have failed. Don't put power on it! Replace the swelled Capacitors with the same Value and Voltage and Size. Those bad capitors will cause a myiaid of problems.

LG Flatron W2253v backlight blinking.


The powering off and on the back light is due to bad capacitors. Go ahead and explore the internal power supply. This is a very common issue on LCD I have fixed about 8 of these ranging from 1 yr of use to 9 yrs of use. I own 4 LCDs and have fixed 3 of them. 2-X2Gen, 1 Samsung and one Viewsonic. The latter one is running with out an issue and the one I use the most.
Once you open your lcd look for plunged capacitors. Replace as necessary. The fix should cost you less than 20 bucks
Check this pics for power supply removal, bad caps and new caps.
Well, pictures are over 4mb let me know if you are interested in seeing more pictures relating to this fix.

The hp mx 705 monitor was working,then it just went blank and black. the power button light, just blinks green.


If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...

I am sorry but i failed to mention the hp l1706 monitor i have makes a hissing noise when on thank you to ghasson for answer but maybe you could help again


a hissing sound from a monitor if its not coming from internal speakers but inside the case, try looking through the air vents with the lights turned out and the brightness reduced. If you see a blue light inside the computer it is usually a High tension leak. Better not to touch it and please turn it off and have it serviced. Opening it up and touching it could be lethal get it to a repairer

Acer al1916b high pitched noise when on standby.


Sounds like you could have an open ground? Also might check the wiring to see if you have a faulty connection in VGA cable or power supply cable

Power Problem


The hissing noise on your speakers is because of arcing. Do not try to operate repeatedly or you may do severe damage. The most likely culprit is the inverter board but you will have to disassemble the monitor to find out. Any loose connection that results in an arc will create noise on speakers. Hissing is usually a result of the high frequency/ voltage output small enough amperage to not blow your power supply If it were a DC arc you would just get a one time pop.

Mag Innovision 765S power supply light blinks and monitor power led blinks and no picture


I'd suggest looking at the mainboard. I assume the blink is rapid? A slow on, followed by a short off and back on again is normal. The fast blink thing is a mainboard issue, and the absence of blink (or light) is power "supply dead."

There is a problem transistor on the mainboard that seems to be the problem most of the time. Replacing it takes about 5 minutes if you have the tools and the talent, and the parts cost under 3 bucks at Radio Shack. Just pick up a pack of NPN switching transistors and de-solder / solder your way to a working monitor. There's usually only one on the board, so it's easy to spot.

NEC P1250+ hisses and scrren blips intermittently


I had the same problem. Your monitor is warning you of failure. The hissing sound is the picture tube powering up. The momentary blank screen is when the power supply for the monitor has become hot. Your monitor is getting ready to quit. My suggestion is to buy a new monitor. To have a tech repair it would be more expensive then buying a new one.
