Re: Mismatched caps?

I got a replacement cap with the right rating, and put it in. Then I did something stupid. I had the PCB plugged in for testing and I picked it up carelessly, zapped my thumb, and now nothing will turn on or light up, not even the power indicator. I'm assuming I shorted something because without a cap in it the front LED would come on and the backlight would flicker and die. Time to give up.

Re: Mismatched caps?

Thanks for the multimeter links.
Yes, that's my board exactly. I'm not going to be able to buy a new multimeter for a while (money is tight), but I wonder if someone would be kind enough to test it for me. If I knew for certain that a 25v cap would work, that would save me time and money.
As for the bad solder joints, how would I test those? They LOOK fine to me, but I'm not the expert here.
Thanks!

It's a Dell E153FPb, power board BENQ DS-1107A.
I tried to use my 1.3mp cameraphone. Believe me, the pictures aren't worth posting.

Re: Mismatched caps?

My multimeter is definitely dead.
I don't have a decent enough camera to post clear pics. I tried to take a few but they aren't legible.

Re: Mismatched caps?

Thanks PCBonez and retiredcaps.
I scoured my PCB for a voltage rating for about five minutes to no avail.
I plugged the monitor in, and attempted to test it, but either my multimeter is dead (likely) or I did something wrong (Also likely).
I can just put the multimeter probes on the traces/solder sockets where the cap used to be, right? If so, my multimeter is dead. I set it to DC (50v) and then DC (100v). It didn't jump even a little.
Something I noticed is that the screen flickered a reddish hue briefly and died. It did that every time...

Re: Mismatched caps?

Sorry, but I only have more questions now.
1) What setting would I use on my multimeter to test the circuit?
2) And I'd have to run power through the monitor to test it?
3) What would happen if I used a higher impedance (500uF, 1000uF)?
4) What would happen if I used the 25v cap and it was a 35v circuit? Would the cap blow or would it damage the circuit?
Thanks!

Can I replace a blown 470uF [b]35v[/b] cap with a 470uF [b]25v[/b] cap? I pulled apart a monitor earlier, and there was one bad cap. The only cap I have that matches the microfarad rating is rated ten volts lower than the bad cap I pulled. Should I just pony up and get a new cap from Radioshack?
What would using a higher microfarad rating do?
Thanks!

Edit: How did this wind up in the audio forum? Whoops. My bad. Can I replace a blown 470uF [b]35v[/b] cap with a 470uF [b]25v[/b] cap? I pulled apart a monitor earlier, and there was one bad cap. The only cap
