HP 54110d Oscilloscope help needed...

[Htguy]

Hi,

I just got an HP 54110d and the unit says it failed power-up test.
It does not display any errors and it will display a slightly broken
test patter signal from the test signals on the back of the unit. (The
verticle rise part of the square wave is spotty, but the horizontal
part looks pretty good.) Any thoughts on fixing/adjusting this unit?


Thanks

God bless...

Mark,
I've posted some troubleshooting info on the 54100 before. Do a google
search on the 54100 as that is the Black & White version of the 54110.
It sounds like the display board has gone bad (large board under bottom
cover). They failed along with the A/D (one for each channel) and
sampler (one for each channel), so did the trigger board and trigger
qualifier. Pick up a used 54110 or 54100 for parts.
