Tektronix 2445B No Readout Display

[tec5c]

Hi all,

I recently got given a Tek 2445B with the fault description "No display" I ran it thinking that it meant no display at all and it was displaying the traces fine. I then tried to turn on the readouts and haven't been able to get them up.
Is there anyone here with knowledge of this bit of gear that has seen this fault before or would know of some places to check? I'm hoping it's not a discontinued IC at fault here...

Thanks in advance.

Hi tec5c,

Do you have a manual for the 2445? If not here is a link to download one. http://bama.edebris.com/manuals/tek/2445/

Does it have the readout PCB still in it? The readout PCB diagram is on page 238/239 of the manual.
