content: Managed to grab one of these off eBay with a duff display. Only £13 inclding delivery so not the end of the world if it's not repairable. The display is the classic fade to black which appears to be a common end game.It hasn't arrived yet but I've been doing some research into LCD display interfaces.Turns out the humble DT830 meters from China have a strikingly similar display atrangement, the same number of pins and what appears to be the same orientation of display to connector. The actual module is close if not the same in size (using some extrapolation from board layouts as I don't have engineering drawings of the 8020. The reference DT830 model I'm looking at is one another member pointed to labelled as a D03046 from CPC for a surpisingly small £2.68!Until I get the Fluke, measure it and reverse engineer the DT830 display, no answers for certain yet, but what do you think the probabilty of the pinout being the same as the cheap ones?If it isn't I'll coax it back to life the hardway i.e. mod it and wire a new display module from RS into it with kynar. Deserves a better life than a trip to the skip.

content: Yeah that's exactly the plan if this DT830 idea doesn't pan out. I will find out today or tomorrow

content: Well this is disappointing. The package has been delivered but not to my house or any neighbours. Reckon it got dumped on the doorstep, signed for by RM and stolen.

content: Well this is well and truly gone, the seller is being a wanker and because there's a signed POD, I suspect I'll not get any money back from Paypal either.Only £13 but bloody annoying as a poor Fluke 8020A I was going to restore is now in the hands of someone elseIncidentally after speaking to the neighbours this is a VERY regular problem around us apparently. I just haven't been cursed with it.Some advice: as a buyer, if there is a signed for option with something you are buying, skip it unless it's a private courier and not Hermes. Always pay via paypal wholly with a credit card only so you can chargeback if it doesn't turn up.
