I have a Viewsonic VX924 monitor that has died. The screen is black, but around every 5 second it'll pulse the input image for about 1/4 second. The green power light on the front flashing all the while. I did a little research and was informed that it is a power supply problem, specifically with the electrolytic capacitors. Upon examination I noticed that 3 out of 6 elec. caps on the board were bulged out. I replaced all three but it is still doing the same thing. Has anyone ever come across a problem like this?
