No truth to that.

Sony power supplies never have any problems, that I have heard of in the last 20 years. If he can sell you on putting in a non-needed power supply board, you should also ask him if he has some great swamp land to sell you in Florida, too.
Pioneer Elites of model year circa 2000 yes, but even then, that is the only board in the entire set that has that cold solder joint problem, and there are many boards in those sets. As a very readily fixable problem, it is really not an issue as far as reliability goes on these sets. In fact, it attests to how well that PS board was designed, that it can take the kind of punishment that cold solder joints can cause and still stay stable as a rock, and once resoldered will last forever after that. I have been producing that result for years on those sets, 100% permanent fixes.
This is not
a disposable TV. Today's TVs are disposable TVs, not these CRT TVs. These are permanent TVs, and were made to last back then, and I mean last indefinitely. When their owners have respect for them, they can still show HD that is so substantial that it beats the pants off a lot of the current day offerings out there, many of which don't have near the richness and density of fully dialed in CRT. See my original post at the beginning of this thread for more of the why.
