Having problems with your Computer Monitors ?

Monitor black and green light going on and off

\015 I have the same problem, but took 5-10 tries to boot and have monitor work, temporary solution is to turn your monitor off right at start up and then turn it back on after everything has loaded\015

Answers :


It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.
