I have a tek 2465B (serial# B077725, so could have the infamous SMD cap issues) that sometimes does not start.
Typically, this is in the morning, and after I hit the switch 2-3 times, it starts. This afternoon, I fetched it from my workshead where it had to live for a few days (it has been raining in No Cal last few days), and I must have had to pound on the button at least 30x before it finally started. Subsequently, no problems, started up the first time after ever power down. (tried this about 8x tonight).
When it doesn't power on, no fan, no front LED's nothing.... Made me think that I had not plugged it in. Read about the "ticking" state on startup, but could not hear any ticking (but perhaps I should ask someone with better hearing...)
As far as I know, there has been no power supply re-cap. Once it starts, seems to work fine for its age.
I saw where some folks had to replace the power switch, but that sounds like a hard failure to me and not an intermittent problems.
Suggestions to start?
Thanks
Mark
