This is my first post to the RCA 38310 thread since joining the forum earlier this week. My 38310JX4 has continued to deliver a great HD picture since I purchased it in March of 2001, displaying no capacitor/diode problems to this moment. But I've never been a believer in the "If it ain't broke, don't fix it." adage.
In an effort to help the recent contributors to this thread who are experiencing power supply problems, searching for parts(capacitors/diodes) or getting $650 repair estimates for power supply repair/replacement, here's what I did to try to avoid the same problem for two of three more years. Yesterday (3/27) I ordered a complete power supply board from Sears Parts. Their price was $80.90 plus about $20 for shipping and handling via UPS Ground for a total price of $102. The board is due to arrive by or before April 9. I'm assuming that the board will contain upgraded capacitors and diodes. Even if that's not the case, I'll have the option of installing it anyway or returning it for a refund within 30 days.
Having reviewed this thread for well over a year, I'm convinced that my approach is the best way to prevent or repair the power supply problem. As MattL, in an earlier post, observed: the power supply board is a relatively simple snap-in module. I confirmed that by pulling the back of my set early this week. A quick examination revealed a couple of diodes with warped and sagging cases and capacitors that didn't match the light blue/gold color configurations of the upgraded ones. The board on my set contains two gray capacitors with maroon and gold bands and a third capacitor right in the middle of the board with a sky blue case and yellow/silver bands. I wouldn't have a clue as to which capacitors, if any of them, should be replaced or if I could solder them properly. Purchasing the complete board takes the guesswork out of the equation.
What's everyone else think? I would welcome feedback from the venerable DrJoe or Ratman if they still monitor this thread. What I'm trying to do is keep the superior picture of this RCA around for two or three more years until 1080P plasmas or the legally-encumbered SED technology present a better picture (and affordable price) than I'm currently enjoying with my 38310.
As soon as the board arrives from Sears, by the way, I'll post the Sears part number and any significant developments during the installation process to this thread.
My set, incidentally, shows 52,000 plus on the odometer. I estimate a total of about 11,000 hours of actual use since I fired it up exactly six years ago this month. Major inputs are a Comcast (Motorola 3416) HD DVR and an LG LDA-511
DVD player modified(hacked) to produce upscaled 1080I through the component output.
