Rejuventaing a '93 Sony trinitron. Should I try it?
I was given a '93 Sony Trinitron today with the usual shorted HOT and power supply transistors caused by loose connections. The picture is still somewhat decent; but, the gray scale is a little off and it's not quite as sharp as it could be. This set has a AKB circuit. I tested the tube on my B&K 480 and the green reads in the upper bad area and the red and blue read in the very low end of the good scale. For some reason, B&K does not make a dedicated socket for these later Trinitron tubes. I made one from a socket removed from a junk board. Has anyone rejuvenated these newer Trinitron tubes with lasting results? I wanted to ask some opinions here before I try it. Id rather deal with a less than perfect picture than get a good picture after rejuvenation just to have the tube die in a week or two. I have rejuvenated regular CRT's over the years. Some held and some didn't. I don't really know how well Trinitrons tend to hold after rejuvenation BTW, I was going to try it on the "clean & balance" setting first. I believe that setting is less destructive than the rejuvenate function.
