Monitor turning off and on

My monitor is going on and off repeatedly with a hummming coming from the speakers when it turns on. I never get a picture as it turns off so quickly. I tried a different cable but it still does it. Any solutions besides getting a new monitor? Thanks

Re: Monitor turning off and on

Apparently this is a fairly widespread problem in 2005 and 2006 and is caused by a backlight failure; usually bad solder joints on the backlight inverter board. HP originally extended their warranty to 20+ months but it apparently has expired since the HP pages have all been removed. This is likely to be an easy repair and relatively inexpensive job by a qualified service technician and is NOT a job for the typical user due to exposure to high voltage.

Screen goes blank when first turned on, have to keep restarting m


If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

HPvs17x power flicker on/off no image, 3-10min after image ok!

More likely to have failing power supply problem due to bad caps, look for caps with bulging top first and post back what you see inside, see example of failed monitors due to bad caps:

No sounds are coming from the speakers. We have tried restarting, turning off the screen and turning it back on, and even uplugging the speakers and plugging them back in...what is the problem?

replace the cable going from the cpu to the monitor. this can be the only solution other than an internal issue with the monitor, or speaker failure

Monitor comes on, then goes back off, rinse, repeat.

Well here is a test you can do. When the monitor goes black, take a flash light and hold at it a angle towards the monitor, if you can still faintly see the image then you have a blacklight/inverter issue. Another common issue with this is the capacitors on the inside. They will also cause this. If you dont see an image then the inverter will need replacing. As the steps for replacing all of this are quite long, ill post a few helpful tuts :).

For replacing the backlight:
For checking/replacing bad capacitors:

I know these arent your monitor but its generally the same idea with all of them. If this doesnt work it will be a inverter issue and if it comes to that just let me know and ill be glad to help :D

The monitor turns off and on repeatedly.

Is it desktop or laptop computer?
If its desktop the data cable might be loose on the back of the desktop computer.

I'm frustrated. Love the picture on my Acer 22" monitor with speakers, but the sound is very poor. I have the volume for the computer turned up, but still can barely hear the sound. What can be done to...

Built-in monitor speakers are usually not the best quality. The monitor should have it's own volume control have you tried adjusting it?

You can use external speakers by plugging them into the same jack in the back (green) of the PC instead of the monitor.

Acer speaker?

There are two possible problems here. (1). The volume control on your monitor is turned down. With the button on the front of your monitor, find the menu/option button, and look for volume control (2) The volume coming out of your computer is low. Double click on the speaker at the bottom right of your screen, located on the start bar. Use the sliders to change the volume. This should fixya up.

Good Luck!

The monitor turns off and on repeatedly.

There is a loose connector on the cable or the cable attachment on the PC board. Jiggle the connector as its connected and see if this causes the LCD to fire up.

Unstable picture and EEPROM problem

Undo what you did & it should hopefuly work.
Next time don't be overconfident and do things that you are not sure of. It doesn't hurt to ask someone who knows. Here you are lucky to escape with this one. I've come across cases where people have ended up short-circuiting their gadgets beyond repair.

If you have the previlege of having a manual, refer it, read every word carefully and then go about doing things on your own.
