There used to be a place in Garland (Dallas suburb) that used to be called Tucker Electronics. And you can (most) always send it back to the factory.

These guys are out of Houston.

most calibration shops also can repair

Should the inquirer provide the manufacturer of the o'scope and model to better obtain the help he seeks?

If its a TEK or HP or similar, then an depot repair may be in order. If it's an "else", then it may be not feasible (trash and replace).
