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.hth, Andreas

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 ,-)
