Question about HP Pavilion MX50 15" CRT Monitor
Connecting the monitor to a Gateway and the screen stays black. How can I get it to work? I did connect the monitor to my computer and it is working fine.
The monitor should be plug and play, and you've already figured out that it's not your computer by plugging into a working monitor.
This is most likely the power inverter board in the monitor - this is common in many monitors. If the power light is blinking on-and-off, or just staying on with no image, that's the problem. There is a slight chance that it could be the light itself, but inverters fail more commonly.
If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

It is possible that your the lcd inverter board is failing or possibly the back light, i suggest taking the back cover off the monitor and checking the power board for leaking or slightly buldged capacitors, to spot this youll have a dark liquid traces on the cap or on the board, the top of the cap must be flat not bulged, if there are any they'll need to be replaced, you can get them from electronic stores like Maplins, and if you are able to use a soldering iron desolder the the ones of the board and solder the new ones on. Make sure you get the exact farad rating of the caps, it dosent matter to much about voltage as long as it is equal or above the voltage stated on the cap. Also insure that they are replaced the correct way around, check this before desoldering from board.

You should try it without the KVM switch first.
Common problem in this monitor is poor soldering works on the back light assembly, try tapping on the frame when it goes dark. It can also be some where else also.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

It can be as simple as bad caps, or worst case will be bad lamp assembly.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
