Hi,
I don't know why I was removed. I saw the email message, but it was not
from me. Can you please resubscribe me? Thanks. Also, the link to
subscribe was not there. It was just the word, but no link.

Thanks Richard, I appreciate the email. I did look in my spam folder and
didn't see anything from TekScopes in there. I think this forum is valuable
because its good to know how to work on the scopes. I actually have
three scopes at home. I have an old Tektronix 533 which I need to fix. I
have the manual for it. It does show a beam in the beamfinder but that's
about it. I also have a 7000 series scope and I think it works but not
sure. I also have a TDS684 that is in very good shape that I picked up from
a place with old equipment, and I had my eye on this scope for months and
finally got it. When I first turned it on, it didn't do anything, but after
a while, it all lit up, and was ok. when I turned it on later, it did the
same thing as before, so not sure how to fix it. It would be cool if I
could work on it with someone in my area, who has a lot of experience with
these, because I am very aware of the high voltage section. How would I get
in touch with someone in my area? I am in Glendora, Calif. Thanks.

The whole message doesn't quite make sense so I suspect it is
phishing of some sort and you will be asked for all sorts of
personal info.

have the manual for it. It does show a beam in the beamfinder but that's
about it.

If there's a beam in the beamfinder, then it's possible that:

1) the trigger circuitry is not running since beam finder forces a
running horizontal sweep

2) the horizontal sweep is way off center. For a centered trace, the
output of the horizontal amplifier (and vertical) should be equal so
that the plates see a zero voltage differential.

I also have a 7000 series scope and I think it works but not
sure.

For any such scope, get the manual and go through the checkout
procedure. First thing to do (always!) is to check the power supply
voltages.

I also have a TDS684 that is in very good shape that I picked up from
a place with old equipment, and I had my eye on this scope for months and

There's a bit of data on the list about the power supplies. It sounds
like your scope power supply is not coming up for a while, possibly
leaky capacitors, but others would know better.


I'm about as far away from California as you can get and still be in the
continental US.

As a practical security matter, *never* clink a link in an email. Even if it looks like it's someone you can trust.

This is the primary way ransomware and most other malware is propagated. The bad guys are getting really good at looking like good guys 9including personal contacts.)

I use Thunderbird too, the advantage in using mailwasher as well is that you get to preview and delete any suspicious email on the server before downloading an advantage for those of you wary of too much bandwidth being used up.
I also run mailwasher in Sandboxie - belt and braces,or belt and suspenders? as you lot over the pond might say.
I have no financial interest in Mailwasher etc.

   I don't remember if Thunderbird can be set to download only headers or only a limited size. Used to be important if one was on a dial-up (I still have a dial up account but hardly ever use it). Mostly I can spot the junk pretty easily. Its still a PITA but I can keep it from being dangerous. Thunderbird has a set of vices all its own but is free and overall works quite well.
