Good that I could help :-) Usually the circuit inside these DRO units is the exact same as a standard 6″ caliper, just observe the mechanical properties of the sliding strip etc. worked perfectly. My old Citizen calculator lost its second digit some weeks ago. flex. I've had a Panasonic cordless phone/answering machine for 6 or 7 years now and the display is as good as the day I bought it.

Thanks for the tip! @Gyro_John: Be careful with the aoyue, mine caught fire because I had the fan on low and the heat on 320. i fixed two lcd displays today using a temperature controlled soldering station set to 350 deg.
I now understand these displays better, and it was a good shot at fixing the problem! I also managed to fix the controller board that would randomly not start the panel on power-up (think it was a mis-seated ROM chip). Allow it to dry completely by either placing it over a towel or under the sun. http://parts.digikey.com/1/parts/445277-tape-conductive-adhesive-1-2-9703-1-2.html, As Facebook Tightens Their Grip On VR, Jailbreaking Looks More Likely, OpenOffice Or LibreOffice? Too hot may melt it, so try lowest heat first.
Because you cannot solder to the display other means are used to make that connection which are not as reliable.
If I clean the surface with a solvent will I remove the crystal or is it confined within the plastic sheet? First the conductive anisotropic adhesive used The problem is my phone call quality.
Remove the rechargeable battery from the bad cordless handset.
As of the Main Base Unit, that is the part of the system that is actually connected to a phone cord and a power adapter, and the model number printed there SHOULD be something like KX-TG5632, or something like that …
I've NEVER had that problem with any other brand phone or remote. I’ve also used this method to repair laptop screens before as well, the trick is not to overdo it as this will melt the backlight and polarizer rendering your screen a paperweight.

It worked perfectly.
Any tips on cause & fix, please? Forum discussion: Before I just buy another phone, I thought I'd first ask if there's a no-spend fix for this. My phone has white buttons and every 6 months or so I take an extra fine point Sharpie to it and redraw the letters. I just tried it on my cordless phone display and it worked like a charm. head-down over the suspect joint ideally Particularly given the low mass of the Ken Yap wrote a comment on Breadboard Wristwatch.

The full scale would cost over $100 to replace, while 6″ digital calipers are about $10-$20 these days.

I’ll be trying this right away.
His process involves heating the glue holding the LCD’s ribbon cable to the phones PCB with a hot air gun and using a pencil eraser to reattach segments of the ribbon cable to the PCB. good. Ken Yap wrote a comment on Feedback - Hackaday.io. Works great.

Depending on material, the heat can be between 140 and 160°C. If it's a 900 or 2.4, I'd guess there's a transmitter that's keying up periodically. I have the same problem with two cordless phones - Motorola model MD700 series.
Thanks for the tip, I tried on my scientific calculator which was about to get dumped due to this LCD problem.
What other diode can replace it? No. Meaning you will have limited to But using my new Aoyue Hot Air Rework Station which I bought on the recommendation of Hackaday. that is seriously awesome. Ken Yap wrote a comment on Homebrew 4-bit transistorized CPU.

Heat seal ribbon cables are garbage. I’d recommending While I can understand the inspiration here, This is a well known problem when the LCD is moved during a touchscreen replacement, and sometimes cooking it in a low FAN OVEN on the lowest shelf will do the trick.
With only a pencil eraser, a hot air gun, and a screwdriver (for disassembly), [Joe] was able to fix his phone’s screen in just under 10 minutes. It was stuck to the glass, and I thought it was a permanent connector on the LCD — I couldn’t understand what you meant by cleaning the glass. plus it should be easy in the first place because the paste they use for flex cables like that melts way sooner than solder or many of the plastics. Had some success with a broken iPad Mini screen showing intermittent black bar/half pink bar. Try checking on ebay, chopshops usually have replacement lcds super-cheap.
The deep cycling of phone batteries is often something that is overlooked as the tendancy is to put them back on charge as soon as a call is over. The white square on the board is fenced by left and right copper contacts and the voltage is passed to the screen by ‘zebra strips’ which are rubber rectangles made of segments that conduct but are insulated from the adjacent row by rubber blocks sandwiched together.
