[TV] Re: Try again on a RCA Model # P52935

[Terry Johnson <terryj@xxxxxxxxxxxx>]

  Extensive heat in a power supply circuit usually means heavy drain or poor 
electrolytic caps. With the newer type of PWS sometimes filtering problems 
aren't as noticable as with the older rectifier supplies. But with the 
regulators used today filters do not seem to show themselves up as being faulty 
like the olders types of supplies. So check the p/p of your supplies if 
noticaby higher ac, try bridging or tack a new one in place.  Terry J. terry's
