Unfortunately, in late April 05, our F38310 failed to power up ... We purchased F38310 new at CC with 5 year extended warranty in late Nov 2001, and we had been enjoying it on average about 12 hours a day with no problems(it made no sense to turn it off except late night and early morning as someone else will usually turn it back on within 15 minutes), nor with any sign of any oncoming "failure"(even the night before) until the late april morning when it would not power up .... And no, there were no storms that night/morning nor do we seem to have problems with A/C current spikes ...
The Service call :
During the service call*, the tech found a bad diode(CR14104 - **) and blown fuse on power supply board for DM-1 module. Having known about the common problem with several caps/diodes on this board and having the related service bulletins in hand at the time of the service call, I was present, and I had the chance to inspect the caps which are often reported to be faulty. Well, even though this set(a JX4) had never been serviced -- It in fact did have the Blue+Gold "to specs" caps at C14113+C14115-- none of them showed any signs of leakage or deformity.
In any event, not having the necessary diode on hand, the Tech decided to take the DM-1 power supply with him and if possible either try to get a new one for RCA, or he said he might also try replacing the diode if necessary. He said he expected to either have a new board from RCA, or replace the diode and and have it back in our set within about 7~10 days or so.
* - Which didn't actually occur until around 3 weeks after the failure, although we called right away+also ended up calling both CC and the local repair shop several times in that period - most of the time, although they always said they would call us back when appropriate, we ended up having to call them back.
** - As stated in Thomson Service Bulletin #TV-03002 for DTV306 chassis - Which concerns shorted or leaky CR14107+CR14117 power supply diodes, when CR14107_CR14117 diodes are shorted or leaky, they also recommend Diode at CR14104 be checked. Note that in this case, the tech checked CR14107+CR14117 and they were fine ... when he was here at least, all he found was bad CR10104(and the blown fuse of course).
Post service call :
Well, after about 2-3 weeks as I recall, having not heard from them, we of course called. From what I could gather, what they(repair shop) seemed to be saying was that they found more problems with the board, and decided that they had to order a new one, which they said they did. They said a quite substantial cost was involved. It may have been this call, or during a later call that they also said the part was on "backorder" ...
Well, a couple weeks later or so, having not heard anything we called for an update .... This time, they did call us back within a day or so, saying the new board would be in from RCA "tomorrow" and that they would be coming out to put it in. Well --- they didn't show up. Upon calling them again the next day, they said they wouldn't accept the board that was sent .. They didn't elaborate as to why, I could only assume it they refused it on the grounds that it was poorly "manufactered."
With seemingly no "concrete" definable details occuring which I was privy to past this point, and, To cut a long story short :
Bye, bye F38310 :
In the end, what happened was, CC decided to honor their warranty coverage by replacing our F38310 with a new set. For various reasons, of the models they carry, we decided upon a Sony KD-34XBR960. So, They delivered a new XBR960 this afternoon, and picked up the F38310.
While I am certianly satisfied with the final "outcome" of this story, and from what I can tell so far I'm sure I'm going to like the XBR, I do feel CC has, has lived up to, their obligations concerning the extended warranty coverage :
I am also sad to see the F38310 go as it was the perfect set(38", internal ATSC receiver, 2 antenna inputs - which we used with seperate antennas aimed at different markets for OTA HD, /etc/etc/etc) for our needs ... XBR960 certianly has excellent PQ+features/etc(and again I think we'll be quite happy with it), but so did 38310 ...
