Having problems with your ViewSonic Optiquest Q9b 19" Flat Panel LCD Monitor ?

Optiquest Q9 After about 14 months, my 19" LCD Optiquest Q9 monitor suddenly got very dark ( the bottom 1/4 was still viewable, though dark) and then went blank. After it cools for a while I can power it back up with the same results. There is a faint click when it goes black. I have replaced it with another 19" LCD ( different MFG.) which is working fine, but hate to throw this one away if it is repairable. The screen itself seems fine with no pixels missing at the time it went dark. There are

I had this problem with my Q9 and I was glad to find the FixYa website with help. But I will offer more detailed info for novices to make sure you find the capacitors. First of all, it is not easy trying to find out how to open the monitor up! First, set it down flat on it's face, being careful not to scratch the screen. Pop off the cap that covers the stand mount to the screen. You might also want to remove the base by squeezing the bottom tabs to the middle and pushing them out. Once the base cover is removed, you will see the 6 screws holding the base arm to the screen. Remove those and the arm will come off. Now, on the bottom right, there is a beveled slot where you can fit a flat bladded screw driver to start to snap open the case. Move around the case separating it carefully until it is completely un-snapped. Unplug the speaker cable (mine gave me some trouble but I worked it side to side and it finally let go). You can push the videop cable through the the back case to get the case out of the way. Once you have removed the back half of the case you will not immediately see the offending capacitors. You will need to remove 4 phillips screws holding down a metal shield on the power board. You may also have to remove some metal tape covering 2 of the screws. When the screws and tape are removed, you will need to slide the metal shield to the right to release it from a 3 pin connector that the two boards. Be careful that you don't damage that connector. Lift up on it a little and slide it left until the connector is disconnected. Now you can see the capacitors. I only had to replace the 3 bulging ones and that fixed my problem as well. Thanks all for your helpful comments in saving me money on a new monitor!!
Well... I took your advice and replaced the 3 capacitors that were "bloated" for my Opiquest Q9 monitor I bought off E-Bay and was very dim and making noises out the back... and so with spending about 4bucks at radio shack and then soldering the new capacitors on it now works perfectly!!! Saving me lots of money on buying a brand new one. This does work people!!!!

Dell Inspiron B130 was black when turned on. Holding flashlight to screen, could see desktop and all icons. Was able to open programs, etc., while looking with flashlight. Replaced LCD Inverter listed for B130. It turned on fine, worked about 2 days, then started flickering, and went black again. Could this be power surge from motherboard, or backlight instead? By the LCD Inverter I purchased working for a couple of days, I felt like that was the problem, but something is knocking it out again.

Monitor Problems We have a Dell PC that supports 2 monitors. Since July of last year, we've been successfully running one 20" LCD via a DVI cable and one CRT monitor using its integrated cable.
