content: Hi Guys,I just purchased a Used Fluke 179 for 55 USD, the problem with it is the display is unclear/blurred/very few segments are clearly visible.before handing it over to the Fluke India Service Center, I want to see if there is anything I can try on the unit, would appreciate any inputs on this please...Here are a couple of images of the actual unit, these pictures were sent to me by the guy whom i purchased the unit from. I sent these same pictures straight to Fluke India SC and the engineer there said this seems to be a display issue, however he of course gave me a disclaimer that it could be something else too, but I took the risk of getting the meter, physically the meter is in good shape, no signs of physical damage or anything....I have also attached an image that I took of the meter once i got it home.

content: I tried to open the LCD panel, but I think I do not know how this unit opens up, would be great if someone told me how to open it up, I do not want to break it apart.I have taken some images of the insides of the meter, and seems like when i press against the LCD, the segments actually appear to be clear, but that goes off the moment my fingers are off the LCD.Also the 400mA fuse appears to be blown.Now the best part - There are a few things that fell off from the inside of the fluke, a screw, which does not look like something that should be inside it and a rubber pad kind of a thing, more like a soft switch with a conductive element in the center.I need a ton of help to figure this out, before i give it to the service center...please advice..

content: Hi,I have attached the 175, 177, & 179 calibration information from the Fluke US web site. At the end is a user replaceable parts guide with parts identified. The clear rubber item is the calibration button, item # 24.

content: It is still covered under Fluke lifetime warranty. Don't know how it works where you are at, but if in the United States, just send it in and they will probably fix it under warranty. They did my 177.

The other screws are easily visible and straightforward. You'll be able to remove the white plastic shield, and the rest of the disassembly is obvious. I don't remember all the details, but I do remember that it was easy, only after I realized there was a screw hidden under that fuse.
