Re: Viewsonic VE500 monitor

The fuse works fine.

Sorry! Yes, the external power supply passes both tests.

Re: Viewsonic VE500 monitor

Thank you for all your help!

Yes, I made sure the replaced caps were in the correct polarity. Same size, capacitance, and voltage. I also replaced the fuse and nothing happened, again.

Re: Viewsonic VE500 monitor

I just checked it and it reports infinite resistance. I'll check the manual for that type of fuse to replace it.

Thank you for that manual, but the manual schematic does not match the board... Which is extremely odd. Would you happen to have the other version? W2 or W3?

Re: Viewsonic VE500 monitor

I'm not sure. There's one board on the right hand side under everything and another on the lower portion under the fancy high voltage metal cage.

Upon plugging it in, no lights turn on and the display shows nothing. Pressing the power button does nothing....

Hello,

My monitor would display briefly then go blank. I opened it up and the monitor had an obvious bad cap (C9) and I replaced it. Again, the monitor is a Viewsonic VE500 19", Model # VLCDS23722-1W. It still didn't work; no lights turned on. I decided to replace the other two caps (C12 & C13) just in case they went bad even though they displayed no visible signs of damage. The monitor still remains blank without any lights turning on. I don't know my next plan of action. Any thoughts? Thank you.

Note- I do have access to an o-scope and DMM....
