Look up Sony in the phone book, or go to their web page, and find out how to
get in touch with them to find someone qualified to do the proper service on
your set. I am sure that there are independent shops in your area that can
also do this, but you want to have one that the tech is really familiar with
your set, and does not just want your business.
Considering the age of the set, if the set was used every day, I would be
very surprised if the CRT is still in very good condition.
Well this is the thing. I already spend $290 getting the power supply
fixed, it doesn't seem wise to spend anymore on such an old set.
This is the sequence of events:
1992 to Sept 2004 more or less trouble free.
Sept 2004 power supply broke/fixed by Sony Tech/set returned to me.
Setp 2004 to Dec 2004 TV working, but unusual CRT color shifts.
Dec 15 2004 no picture/Black screen/sound only
Dec 25 2004 TV restored after soldering on A and CRT boards.
Whether the tube is good or not, I'm not sure.
If you'd asked me before the power supply went bad, I'd have said a
definite yes. After the fix, the picture behaved in a manner that I'd
never seen before, and it was that way until it failed completely,
about 3 months later. During that 3 months, the tube looked like it
was under stress, color shifts during extended high contrast scenes -
which eventually would return to normal after a couple of hours.
I tried to mitigate it by turning down brightness and
contrast. It was getting lower and lower as time progressed.
But since I did my recent fix on Dec 25, the whole thing is more
stable. The colors/brightness/contrast are better balanced. I
don't see evidence of the CRT straining like I did.
Now, whether some damage *was* done, who knows?
I found a post by Louis Carliner who mentions that
a good setup can be made by using "Video Essentials".

perhaps I'll track down a copy.
To be honest, I'm just pleased I got it back to as good as I did,
apparently as much by luck than anything else!
