There is a DALLAS DS1742W-150 Timekeeping RAM that might or might not be the problem.
Some time ago I had a TDS 3014B that got stuck on the flash screen. Fortunately I had
a scrapped main board from another TDS 3000 and as last resort before scrapping it I
took the DALLAS chip from the scrapped board and installed in the scope. Much to my
surprise it solved the problem so it could be worth replacing yours.
Another thing to watch out for is the F/W version. There was one version that
could mess up the NVRAM quite good due to some memory address issues. It was v3.12.
