Hi:

It figures that with all the Tek TDS3000 series scopes I've been
using at work for the past 8 years, that the TDS3014 I bought and
paid for with my own money at home would have the LCD screen fail!

Tek wants $1300 to fix it. There is a TDS3VM VGA output adapter for
the thing. It can be had for $200. I think I'll get it.

I could also inquire about the cost of the screen component, and
consider doing it myself. But that has the risk that it may not the
correct component. The VGA adapter, if it works, would confirm that
it's the LCD panel, but after getting the adapter I might as well
just use it and not spend any more money.

I never need it to be portable, so it's not so bad. Could actually
be advantageous, since I often look at signals from about 2m away,
while changing program code for embedded micros at my desk. Using a
cheap LCD monitor pegged to the wall might make that easier to see.

I also have an Agilent MSO6054 at work which I love. I might not
buy another Tek next time I want one at home or at work.

Anyone have any sense of which maker has more LCD or other failures
in these cheap plastic scopes these days?



P.S. Sorry to hear about Tony Williams. My heart goes out to his
family and friends.




What sort of failure? Could it be just the backlight?

Not only that, but is it past the warranty period?

Either way, a quote of $1300 to repair it is ludicrous.

Yes.
As a TEK scope nears the end of it's Long Term Product Support(LTPS)
period,Tek raises its prices on parts and service to "encourage" owners to
buy new equipment.You should check TEKs website to find the cutoff date for
your model,ASAP.


Thanks for your replies.

When the scope is starting up, horizontal bars of varying display
contrast flicker across the screen. After a few minutes, there are
only occasional flickers, but the whole screen contrast is terrible.
The white-on-grey soft menus that are displayed for instance by the
"Quickmenu" button are barely visible.

Overall backlight appears uniform, and the low-med-high levels appear
to work correctly.

I recall hearing years ago that folks had to pay about $1200 to fix a
failed LCD. The reduced prices for LCDs obviously haven't percolated
into Teks replacement parts. There is a lesser model of color Tek
scope that I heard someone had to pay about $450 to fix.

It is well past the warranty period. I think I bought it in 2001.
Maybe I will consider extended warranty next time. But I will also
give Agilent preferential consideration!


Good day!



Here's the TDS killer;
AFTER the LTPS period is up,parts will NOT be available for your scope
model,unless they share the same part number as a currently supported
scope.Only CAL service will be available after the LTPS expires.
NO exchange modules,they all go to TEKs salvage store as scrap.
