Thanks for the respect you have shown me on these issues, Dave. Appreciate it.
Much as I need the business of resoldering these boards on my own, since very few CRT RPTVs are getting calibrated anymore while being swamped with the continuous flow of fixed pixel, the more that actually get saved by somebody's
resoldering process the better. CRT is still the best medium out there, as evidenced by the Screenshot War!!!!!!!! thread,http://www.avsforum.com/avs-vb/showt...00831&page=148
and there are still enough of us CRT afficianados around for CRT to still be the best for years to come, emminently worthy of the finest calibration attention. Flat panel may look sexy, but it still does not have the maturity CRT has gained thru many years of use and renovation and fine tuning. With floor standing front speakers on either side of your Elite CRT unit you need its depth anyway, and that same depth puts your screen 2 feet closer to your eyes than flat panel does. 2' is a huge
percentage of the eyes to screen viewing distance most home viewers have in their viewing rooms, and when you compromise that with getting a flat panel, you have to get a commensurately bigger flat panel - with commensurately huge cost increases - to compensate and wind up where you started, as far as size of viewed picture goes.
So I have no problem with my CRT set being thicker than a flat panel. I actually like that. Puts it that much closer to me.
So I am going to repeat something you'll find in this thread if you look, but it could take you awhile.
What does NOT need to be resoldered are the test points, the heat sinks, and anything else that has already been soldered correctly.
Test points go nowhere during operation. The only thing connected to the heat sinks is a cap - which means the heat sinks are directly connected nowhere
in there, as such needing no resoldering. And many of the joints were resoldered later and are still glossy and gleaming, like good/well soldered joints should be. This would include the big resistors, the horizontal output transistor - THE
main power supply part - and the 4 leg diode bridge, among others.
Everything else - 99% of the board - still needs to be resoldered, including many super small joints that are really close to each other and very prone to a "solder bridge" happening between them. Which of course is a dead short, and NO circuit design can sustain misconnections like those without a high risk of damage, both to the board itself and to boards and other circuits downline from it, since this board - the power supply board - directly
powers up the entire unit.
That's why the inspection process afterwards is so critical and cannot be skimped on, timewise. It takes what it takes, and I always triple
inspect my boards before sending them out, make sure I haven't missed anything.
Those of you who have seasoned, exprienced techs or assemblers closeby might want to print out these messages here - including my last post, which also contains critical info for any tech wanting to actually take this task on - and take them with you when you interview your local tech.
Those of you who simply want the tried and true Image Perfection resoldering job done on your PS board and don't want to take any chances, do the Gold Standard and send your boards to me. The Gold Standard is well within reach of anybody who paid $5000/6000/7000 for these units back when they were new. Some I've heard of paid over $12,000 for their 710 back then. Doesn't matter how much - or how little - you may pay for a new HDTV today. What matters is that to not keep your set going, you'd be throwing away that original $6000/6000/7000/12000. That means whatever you pay for a new set today, add that to what you originally paid
back then, and that's your actual
total expenditure, deal done, today.
Thanks again, Dave, between us maybe we can continue to save these boards and the Elite CRT units they power up. I have already saved tons of Elite and non-Elite CRT units so far, and intend to continue to keep saving them for years to come. For optimum performance each one saved will need cleaning and calibration, and to be brought back to new condition, which is also very affordable. And better than new status if desired. I intend to be here for that as well.
With your help here, maybe even more of them can be saved.
