Is it Suscon SJ series capacitors?

bloodmaster · August 30, 2010, 8:01pm

Yes!
I replace them with same brand only this time i put 1000 uf instead of 560 uf they had-i will have any promblem?

I think no, this capacitance can vary in big range without any problem.All new production use Suscon MG series - it provide three times longer life time and I hope quality can be much better.

I think I have the same problem. I think it may too be capacitors.

please contact the seller to exchange this device for a new one

they say out of warranty

then you can find someone with soldering skills and replace the mentioned capacitors yourself, this should be quite an easy task

I think I will, my 30w radioshack solder iron, is not enough for circuit boards, and my torch is too much lol
