This VE155 uses wallwart 12vdc 3.5A power supply, you need to check first to see if it is putting out 12vdc.

i would start looking for a nice 22" LCD monitor.
Your monitor was manufactured by phillips and this symptom is very common. The crt gun gets week and has low emissions. The vid card driver has very lillte to do with the brightness control. However if your card is one of the newer nvidia or ati cards there are control ls in the software for brightness. color temp. contrast ect. Doesn't hurt to check but my guess is monitor.
Check out a LG or view-sonic for new ones.

try to hook it up to a different monitor first to verify its the monitor problem and not a bios, driver, or pc problem. if an alternate monitor works, then you know something happened to you original display! If the alternate does not work either, but it does work other machines, then its something else: graphics card, wiring, etc. hope this analysis quickens your solution.

fixing a LCD monitor require you to have some basic electronic know how.. changing the backlight won't be easy as you need to dismantle the whole LCD right to the screen..
But if the display only lasted for few minutes and then the whole screen turn dark, this is due to bad component on the board.. most probably capacitor...

Use brighten controls on monitor to lighten

sounds like the power supply inside of the monitor is going bad. did you replace the cable from tv to the wall?

Hold down CTRL+ALT and hit the up arrow.
That should rotate your screen.

chenge Monitor brightness &contrest settings after you see how it monitor

Does the TV have a light sensor? If so, turn it off.
The light sensor limits the backlights intensity at night or when it's dark in your room in order for better vieweing convenience.

If you are in a dark environment, it really pains your eyes when the view is too bright. Same works the other way around. If it's day, and light in your room. The light sensor will dimm the backlight for it isn't needed.

Let me know if this solved your question.
