Re: Snap in Capacitors

Replaced the caps myself (first time soldering a board!) and the two snap in fuses that were blown. The tv has been on for five hours so far, no hissing or issues whatsoever. yay!

Re: Snap in Capacitors

yeah, that's how I looked!

Really hope the power surge that tripped my house breaker didn't fry anything else on the tv. Is this likely? Nothing seems wrong to the naked eye or nose but I haven't exposed every board to look at it, either. All the connectors that were plugged into the board look perfectly normal.

No, I wasn't hurt. Glad I wore sunglasses! When I saw the cap jump, I backed away and then it exploded in flames. It exploded so hard it ended up jammed into the heat sink next to it so I had to pull out enough guts to loosen it up. You can see the dent on the top where it was wedged. One pic is the guts I pulled out and the other pic is the shell that remains. I think the fire burned up most of the oil because the surrounding board was mostly covered with tissue and metal bits.

I ordered replacements from Digi-key (thankfully...

Re: Snap in Capacitors

FYI-

About an hour ago, I was running my Samsung lcd tv with the back off to see what was hissing before the picture went out. I heard the hissing start and leaned closer to the power board to pinpoint the source. One of those 450v 150uF caps jumped and then exploded into flames! Scared the crap out of me, to say the least. Earlier, I had changed out the 2200uf caps like everyone else and that didn't fix my problem so I had to do something more drastic and this definitely showed me which caps are bad! Now I know what the inside of a capacitor...
