Well

I recieved all new caps and replaced them. The monitor is doing the same thing. It flashes from a white to grey to a darker grey and keeps doing this. It switches colors about every second. I have tried diffrent cables and get the same. What would be the next most logical reason for this, and how would I go about testing it????

Thanks for your time!!!

Thanks for the replys

I was looking on the net for caps and was looking on mouser and they had so many diffrent styles of caps. What do I need?? Axis? Radial? Snap In?? Is mouser a good place to but them?

Thanks

So would I be safe to assume that the caps are my problem??? Should I replace all of them on both boards???

Thanks

Re: HP W2207 no screen no power buzzing!

I guess I have never seen a blown cap. I just checked some pictures and it appears I have a few. What are the chances that is the problem? What kind of caps are recommended on these devices???

Thanks

Hello

When I first turned it on I could see the screen switch from 3 diffrent colorl. It went from Balck to Gray to a lighter gray with lines going through it every .25 inch or so. There was a hum in the back sounding like maybe a mouse??
Today I was going to take some pictures of the screen colors and post them up here but when I plugged it in all I got was...
