Sony XBR Questions

[Dave A]

I picked up my 970 about 7 years ago and it ran fine for 3 years then the 7 blinks started. Not knowing about the chip and only able to find some more generic tips, I replaced the entire AZ board. STDBY supply. I got the last board in the world and I got lucky. It is still going strong and I have a board to change out in the future. I did check the bdent website from the video and they still list them at $7.95 each and they have the proper markings as original. May try a few. EM...could you do testing via surface mail?

OT on the 970. Does anyone know which service adjustment would get me to curing a right edge bow towards center? I have the manual but not sure which one does the trick.

If your set has the same chassis I could probably test a board (if I understand your question). I need to figure out the best way to unplug the wires from the FBT to the neck board though. If you know the right way to remove them I'd be interested in knowing.

To answer other questions as a collector of heavy bulky tube TV consoles, and someone who keeps much of his collection on the second floor, and the rest as well as the workbench in the basement I've learned to bring the tools to the set when it is not as easy to do it the other way around. If I was persistent enough to remove the above-mentioned leads to the neck board I could have done it downstairs, but they were not coming off easy and I decided against forcing things.

I used a vacuum de-solder tool (IIRC it is called the Solda-pult)...The largest size I've seen sold (~12" long)...Normally that tool gets used on tube electronics with larger solder blobs. It was not ideal (I wish I had a smaller one), but repeated heating and vacuum cycles (and a touch of fresh lead solder) did the trick. I did have a 25W iron which is more appropriate for PCB work than the 75W-150W cattle prod irons I normally use on the older stuff.

This for me was an exercise in soldering finesse.

FBT wires on late Sonys often need a special tool. They shipped without wires.
Dont remember if they could be removed any other way.
