Hi,
today my monitor suddenly went white so I did some searching and found this forum.
I got this monitor from someone who wanted to throw it away and I was lucky that it only had a few blown caps.
After replacing them, the monitor worked again (well except the DVI port, the VGA port worked fine).
Now after about one year using it I got another problem: The screen suddenly went completely white (no flimmering).
The pictures below are from the Powerboard and the second last picture (or the attached xlsx file) contains some data I took with a multimeter.
The first table are values for the IC named "IC101" the label says: "f DG13" "B" "DM0565R"
Found in pictures 13, 14, 26. The numbering if the pins are from bottom left to top left then bottom right to top right as seen in picture 26.
The diodes can be found in picture 13 and 26 except D104
D104 is found in 17. Its label says: "JN606" "MBR 20100CT"
Which as you can see in the data image is not open in the reverse case, but I still have to desolder it to make sure.
The bridge rectifier D101 can be found in picture 6 and 25
Fuse F301 can be found in 6 and Fuse F101 in 5 and 21
After searching this forum a bit, it looks like often a blown fuse is the issue.
And indeed after testing, the fuse (F1, in the last picture) on the lengthy board is open.
One question I have is with what should I replace the blown fuse F1?
There isn't any amps value on the front side and I'm hesitant to lift the board so I can see the backside as there are very thin circuits attached.
I'm currently planning to replace all the caps (except the big one) and the diode D104 if it is faulty after I desoldered it.
I don't know about IC101, so I'm hoping you can tell me if it is fine or not with the data I provided.
If you have anything else I could check or do, I'd be happy to hear it.
(I still got many pictures of the other two boards so if wanted I can post them too in the next post)
