tektronix 2467

[[email protected]]

Hi. Anybody out their who can help? My scope died last week as I
turned it on. It came on fine and then the 4 horizontal lines slowly
faded away (no signal hooked up) and seemed to fall towards the bottem
of the screen. - seemed to take about 10 seconds all told. Now it
won't even complete the error diagnostics and of course no signal on
scope!
I think it may be an electrolytic capacitor given the time
constant but I am open to suggestions before I pull all the
electrolytic capacitors in the darn thing and replace them.

first check all the LV power supplies for proper voltage and ripple.
The PS uses low ESR 105degF electrolytic caps. don't use regular caps.

Do as Jim proposed and check the LV power supply. The Tektronix
2465/2465B is build very similar in the power supply area. Service
manual is recommended. sbc.bama.edu will be helpful for a download.

if he had a Dick Smith ESR meter,he woud not have to replace ALL the
electrolytics......

Hi Jim,

well you and me both replace only the suspect electrolytics. But this
could be because we both know what we are doing due to experience ,-)
