Image on monitor only stays for a few seconds but the power light stays on. If I shut the power off and turn back on it does the same thing. Tried on another computer, same results.

What variety of monitor is it?

Assuming an LCD, that symptom is commonly a backlight inverter fault, occasionally a faulty lamp.

Thanks for the reply. That's what I was getting on Google search. It's a 15 inch Dell flat panel.

Unfortunately, unless you can contemplate a self-repair or have a technical contact, a 15" probably isn't worth getting anything done with.

In case you feel like recovering a little cash, post it on craigslist or ebay with model number and a truthful description of what's wrong and someone local might buy it from you for 30.00 or so. Dell backlight inverters are pretty cheap and some make some cash repairing them and reselling them. It is a gamble though, as the problem might be in the lcd power supply or the CCFL tubes themselves.

BTW a test is to hold a flashlight up to the screen when attached to a booted computer. If you see the login screen or your normal background, the chance that an inverter replacement will fix it goes up.

Hi

I am having a similar problem with my monitor (Acer AL1511).
I turn it on, and although the PC is booting up fine, the image won't stay on the screen for more than a second at a time. However turning the monitor on and off repeatedly (currently around 25 times!) I eventually get it to work. It doesn't then have any problems until next time I turn it off.

It does sound like a 'backlight converter' issue as previously mentioned in this post, since I can see my login screen very faintly from certain angles.

It used to just take 6 or 7 switch-on-switch-offs to make it work, now I'm up to 25 but might be worth a shot for anyone who can't afford a new monitor at this time of year :thumbsup:)

Regards,
Jenny

I think there's a chance it has faulty electrolytic capacitors, and if you can tackle a job like that yourself, or know someone who can, it could be worth trying a repair. Otherwise, again for a 15", it's hard to justify trying a repair if it's going to cost much.
