hello to everyone. this is my first post here and hope someone can help.
I have a 465b with the dm44. I bought it off ebay for $180.
I have been building guitar amplifiers for a few years now.
I have never used a scope before.
I had the scope next to me on its hind legs for a few days while I was
reading the manual and getting to know the scope and some basic things
about it when the accident happened.
I spilled around 6 ounces of coffee right down onto the screen and
controls.
I quickly dried off what I could but a lot ran down inside it.
I took the cover off and inspected to circuit boards. I could not see
any trace of where the coffee hit any of the circuit boards. All were
dry and not stained at all.
Now the scope powers on.
The lights all seem to work on the front panel.
The screen shows nothing, I get no trace at all. ( before the accident
I did get a single trace across the screen ( solid green line that I
did manage to slow down to see just a dot moving across the screen )
The illuminate scale works but again no screen at all.
Is it work the 90 bucks to have Tektronix look at it and then give me
an estimate of how much it will cost?
Is there something I can try on my end? ( I am a ware of the high
voltage inside these things and don't dare touch anything since I know
nothing about these machines)
Or should I take the hit and just get another one?( Maybe auction this
one on ebay and tell the buyer exactly what happened knowing that it
maybe a bargain for someone that actually knows how to fix these machines?
Thanks in advance,
Mark for any ideas on this,
Mark
