    Thanx, Mike from NJ ;^)

    Sounds like you have a much better handle on this than Mr.Praven suggested. I pulled the CRT board off to see if I could figure out where to put the test lead for the Blue gun but without a scematic diagram to guide me there is no way to know for sure? I have heard of the CRT rejuvinators before and always thought that they were a band-aid repair, at best. Kinda like "snake oil"? I rated your reply "almost there" only because I couldn't perform the test as you described it with what you gave me to be completely sure one way or another. Frank

Actually, your description indicates that the blue gun in the tube itself is shorting out. This happens when the set has been on for a while and the metal parts in the CRT guns have heated up and actually contact each other. If the video output transistor is bad then your screen would be blue right from the start. An easy way to prove it is to monitor the voltage of the blue pin on the picture tube socket. It should measure around 150 - 175 volts. When the screen starts going blue you will see that voltage drop dramatically. Quickly pull the CRT board off the picture tube while watching the voltage on the blue pin. If the voltage jumps back up the instant the socket is removed, your picture tube is bad. There are CRT rejuvinators that have the "remove short" function, but that has about a 50% chance of success and I usually find that the short will return a few months down the road.

    Look on the CRT board and the pins of the socket are labeled. The blue pin is usually labeled BK (blue cathode) or just B for blue
    there will also be RH, GK, 2 H pins (for heater), a G2 pin and a couple of G1 pins. Measure the one labeled B or BK. On most Sony tubes the 3 color pins are the 3 at the very top.

    I mean there will also be RK, GK, H, H, G2 and 3 labeled G1.

The drivers side door components ( windows, locks, mirror )work fine. Passenger side door as well as both rear door components and the passenger side mirror controls are not working. have already checked...

if the fuse is good, check the switch that controls the side to side adjustment, these go bad pretty often for some reason,, try flipping it back and forth a few times, and try it,, if that doesn't get it,, your going to have to remove that switching control,, test it for continuity when the passenger side is connected, if it has none, replace the switch
