Hello, I have a VP211b that has worked excellent for five years. Then one day I turn the whole system on, walk out of the room while it comes up, walk back in and find the screen black. By the way, I run four monitors off a Matrox M9140. One was the vp211b-primary, the other three are VP2130b. The other three are only turned on when needed. I simply plugged into monitor two and was able to see my main screen again.
I have a stable green light, it seems to be receiving a signal, but the monitor is black from the time of being turned on. Since it was useless as is, I have opened it up to look at the circuit boards etc.
I have been reading through the threads about VP211b problems and have learned much, and mainly have a question for PlainBill, but input is certainly welcome from all.
It seems that the inverter board is the problem much of the time. PlainBill said in one thread that he found F1 was blown and replaced it on the inverter. I have checked my F1 and F2 with the ohm meter, and F2 gives no reading. F1 reads okay. This looks like a tiny fuse. So where did you get one of these from?
Radio Shack has nothing like this. I don't even know what to call it other than fuse, so I don't know what to ask for. When you ask to see fuses, the little round ones with glass in the middle are all anybody has. And why would it suddenly blow?
All the capacitors look fine. No bulging, bursts or leakage. Very very clean inside despite my six cats that love to hang around my nice warm monitors.
I am not an electronics person, but I like to tinker, and would love to fix this monitor. I always build my own desktop pc, so it has what I want in it. But this is bit more involved than I am used to.
Thanks for all responses.
