Having problems with your LG 22" FLATRON LCD Monitor ?

LG L226WTQBF black screen with blue light on power on button

\015 One evening I come home and find out that my monitor is completely black. The button on this LG L226WTQBF looks like the wings of a bird, when there's a cable (non-digital) connected it lights up blue, but no picture.I tried to find a manual to fix this monitor, but can't find one so thought I'd try posting on fixya.I am a software engineer, and can follow instructions to open, fix and put the monitor back together. Thus far I haven't touched/opened it other then connect to a different desktop machine.If you're reading this and have a suggestion/tip/fix let me know at [email protected],Joel\015

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.
