Re: Dell 2407WFPb Monitor - Bad Cap

I'm back. Sorry for the delay. I replaced the 450V capacitor with the correct capacitor and still nothing. Now I'm convinced that its not the capacitor. Perhaps its the fuse? I bought a cheap digital...

Re: Dell 2407WFPb Monitor - Bad Cap

I'm going to purchase a multimeter for next week when I attempt to repair this little bad boy. Anyway, the real question is: once I have a multimeter how do I use it?

Re: Dell 2407WFPb Monitor - Bad Cap

It looks like all of these 2407s have the same problem. Maybe it was caused by a bad batch of the 450v capacitors?

Re: Dell 2407WFPb Monitor - Bad Cap

Re: Dell 2407WFPb Monitor - Bad Cap

So the capacitor arrived and its a snap-in. In other words, It's worthless to me. The only non-snap-in cap that fits my specs on digikey is out of stock and with a minimum qty of 250. Any suggestions?

Re: Dell 2407WFPb Monitor - Bad Cap

Taicon is a part of the Nichicon family. Thats why I thought there might be some truth to that statement. Anyway, you would know better than me.
