2465A start-up problem


 

Hi all,

I have a 2465A scope here which fails to boot.

It briefly flashes some LED's before going to sleep. No beam finder, no scale illumination etc.
The PSU had the Rifa's replaced and the voltage test points are all fine and within spec.

Obviously I'll be going through the manual, however thought I would post here first, on the off-chance that someone might already know what might cause these symptoms?


Thanks in advance,

James
