RCA CTC169AS sucess story and thanks!

[Andrew Kibler]

Well, thanks to this newsgroup and all of the great people here, I
have a sucess story without having to post a question.

An RCA model F31223GG chassis CTC169AS was given to me broken. Report
was that it was working, then power went out (to the house), the TV was
left off. Power blinked a few times and finally the next day when power
was solid again the TV wouldn't turn on.

Using google's sci.electronics.repair cache I found about Howard W.
Sams Servicing RCA/GE Televisions book and got it from the local
library. Within a few hours (I'm not experienced at fixing TVs really)
the bad part -> C4102 was found and replaced. The syptoms were when the
power was plugged in, the standby power would pulse about 5-6 quarter
second pulses before the over current limit was tripped. 140, 15, and
17V lines from the SMPS were all way too high during the pulses, and
stby adjust R4113 had little or no effect on the standby voltages.

Question - will running a cap a a voltage much lower than its rated
voltage shorten its life? assume the current and ripple specs are all
the same, and met.

Thanks again to all that helped without knowing it.

Negative, worse case scenario is exactly the opposite, when too high a
voltage is applied, breaking then down. Also temperature has a very large
effect on the life time of these items. Many capacitors in specific circuits
have a definitive temperature rating applied to them and it is suggested
highly that standard be complied with when replacing them.
