I have a Fluke 73 with a dead display... well mostly dead.

On powerup, at a really acute angle, you can just make out the display.

I've checked the obvious
-battery
-zebra strips
-display (using a differant meter)
-solder connections

Is this a common problem?
Can freezing a LCD display cause this (or other) display problem?
Does Fluke sell parts for these meters or are they "disposable"?

I'm fixing the meter for an old prof, and would really like to get it
back to him.

Any help would be appreciated.

thanks

I had a problem with my 73 once. I removed the display ( 2 or four
screws I think). Than put it back on and it worked! You might clean the
Zebra strips with alcohol( note: dont use anthing else it might melt
something)
Good luck Frank

Remove the screws from the back as Frank says and carefully remove the
LCD glass. You will see the etched strips at the bottom that rest against
a piece that looks like an eraser, clean the LCD glass with the end of a
pencil eraser and then clean with alcohol. DO NOT use rubbing alcohol,
since this contain glycerin and will leave a coating on the terminals.
I've use this technique on Fluke 86's and 87's with success. Good Luck.

I purchased a replacement display for an 8020 from Fluke and believe it
or not, the price wasn't too awful bad. It's at least worth a call and
if I'm not mistaken they might have an 800#. I'd call 800 information.

The whole kit with the display cost around $20-25.
It works for me.

Is the display black, or are the segments blurred and leaking, if so it
needs a new display, Fluke stock the parts (cost Around £40). and yes it
is a common problem.

Fluke's homepage at www.fluke.com has links to their service department.
I got a one day response to a quote for an LCD module for an 8020.
