Know that this has been posted in the past, but wondering if anyone may have a working ambient temperature gauge?  Mine is off to partworks.de for evaluation on potential for repair, but they had emailed me saying they didn't think they could repair it (before unit ever got to them).  Just trying to look at potential for replacement in case they can't repair.

 

Thanks,

Jeff

Interesting! Mine is "muddled" and I'm hoping I'll be able to clean the screen contacts and all will be good.

I've used part works.de on several occasions and found them very efficient, so I'll be interested how they eventually address your issue.

Good luck.

I have fixed five of these for others and tried to clean contacts and all sorts 

 

part works kit is the only kit that works, I have another two spare broken screens awaiting repair in the shed / workshop

 

its actually really easy just fiddly

Hi Waylander, good news about partworks.de, they seem a small but straightforward company.


I've cleaned that type of screen but it was a long time ago, please refresh my memory .... do you use acetone to remove gunge or some proprietary product? Thanks

The screen is a liquid LCD connected by carbon rubber strips, the screen will be finished after 30 years and the carbon rubber strips have biodegraded

 

these parts are in the kit, some gloves good light will help, you might need to assemble it more than once to get the carbon strips lined up correctly with the rear of the LCD

 

i have a guide of how to do a 944 clock, the process is exactly the same, there is a correct cleaner cloth in the kit

Thanks, I couldn't remember what I had worked on ... it was my 944 clock. I'll give it a go myself, then if no progress will get the kit from partworks. Cheers

Just got confirmation from partworks.de, they said unit has a problem with the circuitry, they can't repair.  So I guess I am in the market for a working display unit.  Any leads are appreciated.

Anyone no how the temp instrument bulb removes and the correct identity of a replacement.  I have done the initial disassembly as shown for a 968 clock in Booster's post.  Pretty sure the bulb is the culprit in my instrument's failure.

The bulb is just twist to lock, must just be a bit stuck, and the bulb only comes on with the lights


The display does not have a backlight as its an LCD

Thanks. I'm a bit reluctant to put too much crushing force on the bulb for fear of breaking it.  However, what I understand from Booster's response is that the bulb isn't what displays the temperature, as it is on only with the lights switched on.  I suppose this means that the LCD in my instrument has perished because it had gone dark before I removed it.   For those who have had this failure, I replaced my instrument with a Chinese-sourced remote thermometer.  I have the temperature reading sender located in the right rear wheel wheel, but I belatedly learned that the original instruments had this in the right outside mirror.  Frankly, the wheel well picks up too much road heat to be really very useful.
