Re: seiki se55uy04 Blown PSU 890-pf0-5501

99% alcohol would be the best for cleaning up all the carbon char? What's the best way to check with a VOM? Someday I would like to get a LC tester. The diodes I should be able to test in circuit with diode check. Whats the best way for the fets? Can it be done in circuit?

Thanks for responding

Hi Everyone,

A friend of mine gave me this 55" LCD Tv as it died with a "poof" of magic smoke.

When I plugged it in to see what state it was in, it did nothing, no response to any panel input or remote input. no back light or led indicators.

I yanked off the back cover and noticed a disc cap looking component, with a NTC 3D-15 pn# on it. This is apparently a thermistor. On the underside there is a very severe scorch mark and some traces are blown away. This is where part of the problem arises. I can tell where one side of the thermistor...

Hello All. I hope everyone has had a great Christmas.

I went to college for pc repair and electronics. I repair photocopiers for a living.

Overall I like trying to fix "broken" things. Especially when I acquire them for free.

Thanks
