Tip & How-To about ViewSonic VG500b (Black) 15" LCD Monitor

Power Light blinks on then shuts down - Black Screen

I couldn't find any fix on this monitor so I had to go it alone.......


My VG500b monitor would power on then the power light would blink off. there was no display at all but I could see the LCD panel change in brightness just a small bit during the power on and then power off. I found that there was a bad capacitor on the inverter board. I replaced the 47uF 25v capacitor with a 47uF 35v capacitor. (The 25v would be okay but I always replace a failed capcitor with a higher voltage rating) This capacitor is the shorter form in order to fit under the shield. You can use a taller capaitor but you will have to lay it down, as in bend the leads down and lay it on it's side in order to fit under the sheld when you put it back together. VG500b fired right up and is going strong once again. Hope this helps someone.

How do I turn off the Samsung sync-master p2050 monitor?


If it doesn't turn off by holding the power button down for 10 seconds, then it cannot be turned off by the power button alone, like most modern lcd monitors. Most modern monitors goes into standby mode. To completely cut power, you must unplug the power cable.
I've enclosed a link to the install manual for reference.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Moniter won't turn on/power light blinks green


Yeah, I called Dell yesterday, and they said it was a problem that I could not fix myself. Whether that's true or not, I don't know, but my monitor was still under warranty, so they shipped me a replacement right away. I already got it this morning. 

FYI: Their monitors carry a three year warranty.
