Thanks for the insight. I still need to read more of the posts... figured I'd go ahead and ask in the mean time.
I just received my first Fluke DMM when I went to pick up my second lab grade power supply (Heathkit IP-32).
The DMM is an 8022B with bleeding LCD. Worked fine when turned on in the cold garage to see if it even worked. Now, is consistently looking like this:
***see attached image since I haven't recalled the syntax to post in the message body yet***
I swapped the battery with an 8.4V Li rechargeable to see if lower the voltage had any effect... which it didn't.
Any advice, reference LCD units if that is all or anything else I should check?

Mr modemhead (a member of the forum ) has an excellent blog on many DMM repairs.
Including a nice write up of a LCD replacement like from the above linked thread.
Check it out and follow that method .

FLUKE185/TEKTRONIX TX3
I have a Tektronix TX3, along with the lesser featured TX1, it was Tektronix's attempt to compete with the Fluke 87 and expand beyond scopes. Prior to this they only had a few imported DMMs of no particular interest. Subsequently, Fluke's parent company bought Tektronix and the blue booted TX3 got a new yellow boot and became the Fluke 185 and a sibling, the 187. These were pretty high end even by today's standards. I rarely hear mention of them. Like a previous owner stated about his favorite meter , "you would have to pry it out of my hands". If anybody has any behind the scenes stories or just owned one, I would like to hear about it.

Kind of taking a left turn with you on the thread as this is about Flukes older meters, but as an FYI, I picked up a older Tektronix model 850 handheld DMM off ebay for $50 and shipping. I was looking for the 916 when it popped up. It has good specs, continuity beep is super fast, and I was happily surprised that it tested spot on with the DMMCheck. MrModemhead did a teardown of one here: http://mrmodemhead.com/blog/tektronix-dmm912-teardown/
