tektronix 2246 oscilloscope

[engineer21]

By engineer21, hi new to forum still lots to learn interested in repairing most things inc electronic gear in my spare time, got problem with tektronix 2246 all working fine but top of screen shows icon, OVERV i think may be over voltage, chap i had it off thinks it was fed directly by function generator only thing he can think of that may have caused this fault. Nothing mentioned in manual, the only thing that does not seem to work if you try to measure volts in second menue +peak, peak-peak cursor not working. may be something that can be removed in menue, im not sure, hope someone can help. Many thanks vince
