Title of thread says it all...What are tantalum capacitors, why are they bad, and what do I do with them?
Hi Everyone, My Samsung 52' was doing the on off cycle and squeel, after some research here I replaced C102 & C131 with a couple of SMG (m) 85c 16v 47uF caps I had on hand. Now it will turn on, squeel with the vertical lines until it cycles off then turns on and works perfect. Do y...
Should all 1970's tantalum caps be replaced?
I'm not usually a fan of replacing caps that still work, but these things fail without ANY warning at all. I had a tape deck literally smoke because one of these in the tape bias section decided to short. This took out four transistors, burned several circuit traces. It even heated up and magneti...
Samsung LN52A650A Power cycling, squeal NEC-TONKIN caps
Fixed this one in October 2015, it uses those NEC-TONKIN caps on the main board like other Samsungs that have bad C102. This main board does not have the C102 but has lots of the NEC-TONKIN NERAS7 (47uF 10V Tantalum) so I decided to replaced all of them and have been keeping in touch with the o...
Orion TV26266 won't start when cold
Hello,I've got an Orion TV that takes 10 to 15 minutes to start at temperatures below 18 degrees Celsius. I think it might be a bad caps issue. I was planning to heat up the usual suspects a bit with the tip of my soldering iron, all one by one until I find the lazy one.But now in the summe...
Replace Tantalum With Tantalum?
I am in the very early stages of planning a Sony TAE 8450 rebuild. Will be doing a total recap as part of the rehab. There are about a dozen tantalum caps that will need to go. Their values are in the 3.3 - 47uf range, with voltage between 10 - 16v. I don't know if Sony chose the...
2325 with unstable DC offset. Repaired.
I am working on a 2325 that had many issues. After rebuilding both amp boards, including new outputs, I had a problem with fluctuating DC offset. It was bad enough to cause woofer movement. I plugged one end of an RCA cable into the pre out connections, to separate the pre from the amp, and...
Marantz 2325 Recap / Polarity of Tantalum Caps
Hey Gang I am in the process of recapping my 2325 and need to know the polarity of C703 on the amp board. It is a tantalum cap and I am replacing it with a radial cap of the same value. It is the blue cap in the center of this photo. Thanks!
