MONITOR KEEPS SWITCHING TO STANDBY

Main digital board fault. Check and replace it. If you wish to get more details visit the site linked here. http://electronicshelponline.blogspot.com/

Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .

How old is it? If it still under warranty get it repaired, it sounds like the switch is gone or the energy saving s/w inside is bad and is not detecting when/when not to turn the display on/off.

Hello!!
Maybe this link has the answer that you need! I have the same problem with a LCD monitor

your hp monitor has an electronic component problem inside, probably some busted capacitors or ccfl lamps that failed to light...best is to bring the unit to a qualified LCD repair center near you..

Hi,

It sounds like there's a problem with the monitor itself. It may be that the lamp in the computer is dying, which would explain why it keeps going out. Other possibility is that the monitor isn't receiving power properly either through the cable or inside the monitor itself.

If your're not the kind of person who wouldn't mind opening the monitor up and hopping in there, then I recommend you take it somewhere it can be diagnosed like Best Buy.

Hope I helped :)

Since the screen keeps turning off and sound only remains have a look at the inverter board for any buldging capacitors which look like blue cans, there is most probably a short in the inverter and the powersupply is sensing this thus turning it back into standby to prevent damage to the tv.

This is a problem with the power supply unit inside the monitor, there is no easy way out here. If you keep on using your monitor like this eventually it won't switch on no matter how long you wait. Keep on using it like this for the time being without switching off anything but ultimately you will have to take it in for repairs or otherwise purchase a new screen..

What is "EHP"?
If it comes on back after a week, what do you think?

When it goes "black", is it in standby or is it still on?

Slap rear of case when it happens. Flickers screen?
Re-solder video board; particularly, the Video I.C.

Hi The problem is to do with a 680uf capacitor that tends to bulge and fails.this stops the monitor staying on when trigerd to do so,change this and happy day.
