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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

    Yeah I have the same problem. Power on than it goes black. I figured out that if I set the brightness and the contrast to 0% and wait a few minutes and than Power it on again. Its working like a charm. I can adjust the brightness and the contrast back to normal.

How do I connect the speaker cable from the cpu to the monitor - ca't find a socket at the monitor end H750


It appears that this monitor doesn't have speakers. You would need an external set of computer speakers. Most CRT monitors do not have built in speakers.

The monitor keeps displaying the menu box randomly in the centre of the screen and I can't stop it from appearing. Can anyone help please?


10% chance it is the button of the menu stitch. Can you tap the monitor on the front, sides or corners without moving it or the cable and make it go into Menu?

80% I'm guessing you have a broken but occasionally touching connection wire in the video cable. Take it off (both ends) and go to Micro Center or PC World and get a replacement. This is an odd problem...

Monitor screen goes out (black) 2 seconds after turning on


Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page. Places like yours have no place on the internet and I'm going to find out what I can do to report you.

Thank's for nothing

your monitor does not support the screen resolution that your windows install is set to. hook your pc back up to your computer guys monitor, and reduce the screen resolution, then hook it back up to your monitor.
