Recap Uh-Oh

[0xABE]

Recapped my Q660AV with tantalums. Now no chime at startup (can hear a faint click or pop) and no HD found. I get video out, mouse works, but stuck on the grey startup screen with the disk and question mark. Anyone have an idea which cap(s) may be the culprit(s) before I go back and review them all?

Did you make sure the black band on the Tantalums is Positive while on the original aluminum SMT the black is negative.

Yep. I have polarity correct.

Perhaps upload a photo for us to have a look of the board - might be able to help. Ive done 660av myself as well

I finally got some free time to go back and touch up some solder joints. Works great now! Thanks!

I had the same thing happen recapping my 6100, just a single dry joint with minimal solder not actually making a solid connection. 

always feels good when something broken comes back to life!

I think I was originally being too conservative with the heat setting on my iron. I turned it up, and applied the heat for a little longer than before to make sure the pads and leads both warmed up. Yep, it feels great to have a successful outcome.
