Re: Need LCD display for TEK 2336 scope (or repair advice)

Paul Amaranth

In my case, this was an D802. The LCDs have been unavailable for years, but
I wanted this one fixed since it was my first "real" piece of test equipment.
I have a pile of other handheld meters, including a Fluke 27/fm, so getting a
replacement really wasn't the point, getting it fixed was.

I even bought a similar model off of ebay to scrounge for parts, but since it
worked perfectly, I just added it to my bench.

To bring it back on topic, this was more of an example what might be attempted
with the Tek problem.

If this was a hand-held Fluke, be advised that Fluke has traditionally been VERY generous on repairing, replacing, or upgrading their meters for customers. �In the 80s/90s I was going through these fast enough that I was basically getting new meters for the cost of an annual re-cal.

Yes, operator error....when they ran out of parts for 77 meters, I reluctantly (nudge nudge, wink wink, �say no more) upgraded to a 179 for about 1/3 the cost of a new one.

You might call their tech support line and ask what their policies are today, and take that nugget of info to the next swapfest. �I usually see at least one abused-to-death older Fluke meter every time.

Because of this kind of customer support, I'll be a Fluke customer for life. �But I admit that I have more of those free Harbor Fright DVMs than I have fingers, and they get dragged out more often than the Flukes, because usually I don't need the accuracy-- I just need to do a go/no-go test.

73 and have a blessed day

I had an old Fluke meter that I replaced the old unobtainable Fluke part with
a standard LCD, that i think cost me $3.50.� It involved stringing a bunch of
wires, but it turned out well.� The original part had a zerbra strip and
conductors printed on the glass, the replacement was in a DIP package.

See if you can find a similar form factor LCD; after that it's just a matter of
figuring out the connections and a little engineering.

The manual I have lists it as U37 but I can't find a TEK p/n, it just says "ref U37" and that's it.�
