I have a 3 flat screen monitors that were being pitched,The first works ok except it has no green drive or has green drive that is weak, the second works with the exception of flickers up and down with brightness and thats the one I am using now on this computer. I suspect a power supply issue with it, third one doesn't work at all. I have learned and forgotten lots of electronics but I did remember one thing and that was it is usually easier to fix things that don't work at all then to fix something that partially works. So my first project will be to look at the monitor that does nothing.
I got it open and found the fuse good. I had some trouble getting the power supply board out but with it
on the bench now its easier to look for things. I saw no over heated areas,loose or cold solder joints and
for the most part a really clean board. I did find 3 shorted leaking,bad capacitors. My first project will be to try to locate a source for 3 of those. I am sure those caps were keeping that section of the power supply from coming up.
One thing about this project is that if I fail I am out only my time and a couple bucks for parts and they can still go to the dump but
if I am successful I will have two 17 inch monitors and one 19 inch free except for a few parts and time. They really don't make this stuff to be repaired mainly because of labor. Lets see... new monitor on sale 150 bucks , old one in need of repairs at 65 bucks per hour could cost more.
Thats why we DIY...ha ha.
