content: If you have no luck with Fluke which is rather surprising then have a look around on Ebay, here are a couple of listings below but you will probably need to contact the seller first to check availability and more importantly associated shipping costs, some may not post items to your country so ask about that up front.Random Ebay Listing #1.http://www.ebay.com/itm/FLUKE-87lV-4-Series-89-4-187-189-MultiMeter-LCD-Glass-Dual-Display-panel-/332071464494#shpCntIdRandom Ebay Listing #2.http://www.ebay.com.au/itm/FLUKE-LCD-89-4-89-IV-187-189-Original-LCD-Display-Meter-Displays-Fluke-LCD-/252201243742

content: hey.thanks for the reply.well,maybe it is surprising in australia but not in middle europethe first listing for 15 usd seems good but the seller wont ship overseasthe second one is 40 usd + 22 shipping + becuse it is over 45 usd total,theres an additional 13 usd import charge so, 75 total for a 15 usd screenany other ideas?

content: I have a couple of these meters and I'm pretty sure the replacement LCD displays were worth far more than just $15, not that I've ever had to buy one but I have seen the value of other Fluke LCDs and they can be quite expensive. Anyhow I would send that cheaper seller a message first and see how that works out otherwise keep looking or set up an Ebay alert should one become available locally.The only other chance you might have is if a member here who happens to be located in the US would be willing to purchase one on your behalf and then forward it on to you, being a new member here though I don't like your chances but you never know, either way I hope it works out as the 180 series are great meters, also perhaps you could give Fluke a phone call directly and ask for assistance or even an indication of the screens replacement value.

content: well yes i was suspicious about the 15 usd but the seller states it is a genuine product and the seller has 200k + feedback so probably it is.but i cant text them,they use the filter on ebay that wont allow me even to text them outside from the us.waiting for a set showe up locally here has 0.00000001 % chance so thats not an optionyes an us member is a good idea.if someone in the us willing to buy it for me than send it,would make me very happyi can pay with paypal,so no risk there + i have a 3 year old 100% ebay account as a proof too if neededin the meantime i got an another idea:are there any chance that there is a compatible lcd in some other model?does this screen has a part number or something to check for it?

content: It shouldn't be all that difficult to find the specific part number via a Google search otherwise I can have a look through my collection of manuals and other documentation tomorrow to see if I have it, also it is probably best to let this thread stew for a few days as there are many helpful members here that are in a better position to assist than I am, some are also based in your region so will know the best avenue to take.If all else fails after a week or so then start a thread in the Buy/ Sell/ Wanted section with a polite request for assistance and include a link to this thread and if somebody offers to help don't forget to properly thank them.

content: The service manual is included below and it appears that the LCD part number is 688181 and you will find it at the end on the last two pages. The image is from one of the Ebay listings so I don't know if that is correct or not.

content: thanks for the manualbut the image is wrong,this lcd is for the 87-v modellas i see youre very familiar with that modelcan you tell me what is the difference between the 87-iv 89-iv 187 189 and the tpws?(the model that i have) and how to distinguish them?

content: The image you posted directly above is from an Ebay listing which was sold back in October 2015 from a UK seller, if this is your meter then it appears to be a 87IV or 187 which from memory are exactly the same thing, the 89IV and 189 incorporate stand alone logging and recall functions and can be identified by having the view memory option on the rotary dial selection, in addition to retain the real time clock they incorporate a super capacitor which is prone to corrosion.The TWPS or train warning & protection system indicates that this meter has approval to be used on railways and you can find out more by doing a search. The LCD screen should be common and interchangeable amongst all these models but no LCD from any other Fluke series can be used as a substitute to my knowledge, post some pictures of your meter so we can all see the damaged screen with an explanation on how it occurred.

content: thanks,now its clear to me that the tpws is a 187 since it doesnt have the logging dial selectionyes i just searched a picture on google,since im not at home until mondayat monday / tuesday ill post some pics from iti searched the part number you provided but i found just 1 company (but at least in the uk ) which sells it but as far as i get they just sells to companies but i texted them,maybe they can provide me a solution

content: today the local reseller replied ( after 2 weeks) and gave me a quote from 60 usd ( includes the lcd 37 usd plus 23 usd for the 690883 -Connector, Elastomeric, LCD to PWB1- ) and they said ill probably need this part too because over time that rubber part becomes hard and starts to act unreliablewhat do you think about the price?it seems a bit pricy + do i really need the other part?thanks

content: For a Fluke 187/189, I don't think I would just automatically buy a new elastomeric connector (aka "zebra strip") especially if on a budget. While it is possible that any such connector from any brand or model could develop a problem leading to dim or missing segments on the display, the only ones I'm aware of that had a chronic problem were the early 80-series Flukes. Even then, a good cleaning usually restores functionality.As for the price, it's your call. All I can say is, it is a good multimeter, one of the best Fluke ever made IMHO, so it's very much worth repairing for that price. Good condition used 189s go for USD200+ on eBay.

Stronger stuff might be mechanic's hand cleaner, citrus solvent, and IPA.

content: I use Novus plastic polish for that sort of thing, it takes a lot of elbow grease but it will do the job. #3 for deeper scratches followed by #2 for light surface scratches.

content: I'm sure there must be similar products available virtually everywhere. Novus is a mild abrasive mixed into a cream, as is toothpaste although I think that's an even more mild abrasive. I know from experience that Novus #3 will polish out rather deep scratches but it takes a LOT of work. In some cases it might make sense to wet sand prior to polishing, but only when a scratch is so deep that you can feel it.

content: That looks like quite a deep scratch. When I say sandpaper, I'm referring to something like the 1,000-2,000 grit stuff you use with water, the sort of thing one uses to remove blemishes when painting a car. Very fine stuff.

content: Quote from: alext on February 03, 2017, 01:33:39 pmI have repaired a number of meters in the past most of which were relatively clean inside and on these meters I did not feel it was necessary to add additional lubrication to the rotary dial assembly as the meters were in otherwise good working order. One Fluke 83 that I did virtually a complete rebuild and wash down on was owned by an electrician and it appeared to have been used in extremely dirty environments which probably included dirt, dust and other contaminates. This meter as part of the repair process was thoroughly washed down both inside and out and to retain lubrication on the rotary dial selector a very sparingly smear of silicone grease was applied to the detent mechanism simply because I have ample stock of it at hand.I would not be using pressure pack sprays for this task as you risk contaminating the rotary dial contacts in addition to leaving an oily residue inside the meter which may lead to other issues and problems. There are a number of existing threads on the forum which provide some very good detailed advice in regards to what should and shouldn’t be used one of which I have linked below. As ModemHead is recognised by many here as one of the forums most highly respected and knowledgeable members particularly in relation to these series of meters the best advice and guidance I could give would be for you to thoroughly read and comprehend all of his documented instructions.Mr ModemHead Website.http://mrmodemhead.com/blog/DMM Grease Thread.https://www.eevblog.com/forum/reviews/question-dmm-grease/
