Hello to all.
I have a MAG LT782s LCD monitor. I got this free from a friend's shop. This start out as a "some times it works" to a "deader than you know what".
First thing I did was research. I found this site and found that some people did a cap replacement. So, I did a cap replacement with some caps I had. The power board model is AD-1700 REV: F from Mirage Electronics dated 1,14,2005. There is also another number on the board that is 200-000-1700B VERSION: H.
Here is what I replaced.
6 x 470uF 25v with 5 x 470uF 25v and 1 x 470uF 50v (only had 5 25v and the next one up was the 50v)
2 x 10uF 50v
2 x 100uF 25v
When I replaced the six 470uF, the monitor started to work great. It worked for a day then stared the 2 seconds on then black with green LED. I can still see the screen and what is on it if you look at it in the right lighting. So I know the video is all good. I then replaced the 10uF and 100uF caps and it is still doing the 2 seconds on then black. I can post pics if needed, just ask what you need. Someone suggested that it may be bad CCFLs. I would try replacing them, but I don't have any new ones. I did try some old ones from an old cracked LCD, but it did the same thing.
Any thoughts?
