Starlogic 20 inch widescreen monitor screen keeps going black
When I turn my monitor on, it will stay on for a moment, and then go black. I can turn my screen off, it will come back on, and then go black again HELP
Our starlogic 20 inch widescreen monitor screen keeps shutting off. It comes on for about 5 seconds, then goes black. In order to even shut the computer down, you have to turn it on manually, try to click shutdown, the monitor shuts off, turn on manually again to click shutdown, etc. It is unuseable!
I have the Starlogic widescreen HD20W which is probably what the other person has. The power supply is a separate unit with 120 V going in and 12 V @ 5 amps going out. I took the power supply to my Community College electronics dept to check out and they said it was fine. The "power on" light on the actual monitor stays on whenever the power is turned on, regardless if the screen is working or gone black.

bbkieffer, It sounds like a possible printed circuit board could have failed inside your monitor. You failed to tell if the light in the power on/off button shows any activity??? Some of these LCD monitors do have problems with their power supplys. Every LCD Display has two types of supplys in them. One requires that the first one is working. The main powersupply powers up two things. 1. the digital interface board for the digital info processing that is what you see on the screen, and 2. it also supplies low voltage to operate what is called an inverter power supply that generates high voltage 1000v-1500v to light the cold cathode Fluorescent backlight tubes that let you see what is on the screen. Yes, they are very similar to the new style of curlie-que screw-in light bulbs--- only the tubes are straight ones and run left to right in back of your LCD/FPD!!! You will need to contact Starlogic to find out if they have a monitor swapout program where you send them your nonworking monitor + some cash and they send you a REFURBISHED replacement. Or you could hunt down some local TV/Monitor repair shop that knows how to repair/replace CCF tubes and knows all about switch-mode and inverter supplies.

This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.
If you don't see an image with the flash light, then it could be the main logic board.

Alternate power supply that doesn't have the switching adapter in between causes blackout, I went and found the original power supply and monitor is back up and running.

As for your 15" LCD BENQ Monitor, "1024 x 768" pixels is the Maximum Resolution
If you increase your screen higher than the Maximum resolution you get a black screen! because the monitor cannot support the resolution higher than "1024x768" pixels.
FYI
Here are typical resolutions for some popular screen sizes 19-inch screen (standard ratio): 1280 x 1024 pixels
20-inch screen (standard ratio): 1600 x 1200 pixels
22-inch screen (widescreen): 1680 x 1050 pixels
24-inch screen (widescreen): 1900 x 1200 pixels
It sounds like there's a problem with the monitor itself. It may be that the lamp in the computer is dying, which would explain why it keeps going out. Other possibility is that the monitor isn't receiving power properly either through the cable or inside the monitor itself.
If your're not the kind of person who wouldn't mind opening the monitor up and hopping in there, then I recommend you take it somewhere it can be diagnosed like Best Buy.
You're monitor is dying and you need a replacement (Starlogic brand is notorious for dying early and giving poor performance)
You're graphics card is going out. If you have an extra monitor laying around, take out the Starlogic one and plug in the other to see if the same results occur, if not, it's the Starlogic monitor, if the problem still persists, you need a new graphics card or need to update your current drivers.
I can't find a website for StarLogic anywhere, so either they have gone out of business (not likely as there should be some reference to them somewhere) or they are imported from a foreign manufacturer and rebranded with the StarLogic name.
Have you checked the HZ that you are using the monitor in windows ? If set at a very high level (for example 100hz) it may damage the monitor as it is not supporting it. (and maybe this explains the reason for the shutoff as a means to protect the circuitry)
17 inch TFT/LCD Widescreens monitors are ussualy optimal at 1280x800@60Hz.
Right click on Desktop-->Properties-->Settings-->Advanced-->Monitor--> At this point check the Monitor Refresh Frequency.
Check this first and if this does not solve it then we can proceed to more serious hardware troubleshooting.
