Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.
This is a Optical Block problem and I am glad Sony is working out a deal for you. The cost of replacing the optical block would be too expensive to consider. It will only get worse as it is used.
A lamp issue would never give you a discoloration in a certain area of the screen. The picture would just be dark or no picture at all. It would even shut down if the lamp was shattered in most cases.
This TV has a very expensive panel... we are talking $3000 core charge alone! It comes complete with all the lower buffer boards (which from the sound of it, you are having a problem with). Individual boards for this defect are not available on repair parts list I know of. A panel is what you need, PN: 9-885-063-33
