In other words, "voiding the warranty" as such.
Better to have discussed returning it immediately if a problem was noticed.
A lot of techs are not versed on every possible repair, so perhaps finding someone who's worked on those before is the answer.
Also, since parts have been replaced, other issues may have cropped up, making troubleshooting more difficult.
I actually did discuss the situation immediately and extensively with the seller and he was quite adamant that the table was running properly before it shipped. All of the discussion was in writing so there is a complete record of it all. The replacement chip was a result of that discussion and the sole part change made. The new chip runs whereas the old one did outputted nothing. Given there was no physical damage involved at all there was no possibility of that being a cause for the problem.
The point is that there really must be a solution to the issues, if only we knew the drive better. My tech is highly experienced, but with no definite knowledge of how the circuit is supposed to operate he has hit a dead end in terms of time investment. He would be happy to do some more work if he were not groping in the dark quite so much.
Finding someone who has worked on these drives is exactly the point to this posting, actually.
