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.
