OK, on a whim I treated my 2004 B to a steam clean full valeting this Summer, which I rapidly regretted. Afterwards, I noticed that the digits on the clock were dimmed/missing. I phoned the bloke who did the cleaning to ask about it, and he stated that it wasn't unusual, and it should all be fine in a few weeks after it dried out. Well, it's been a few months now, and he's since gone out of business (surprise!).
Does anyone know if it's possible to repair the clock, or will it need replacing?
Thanks, Jeremy
 
Hi,
Never had B or seen the clock from one, but dim / missing segments is a common problem with LCDs. It is normally caused by poor connections between the glass of the actual display and the electronic circuit board. A common method of making the connection is a directionally conductive rubber strip. These are commonly called "zebra" strips and are made from alternating layers of conducting and non-conducting rubber giving a striped appearance. Contamination or excess pressure can cause bad connections. The cure is to disassemble the circuit board, LCD and zebra strips, clean and re-assemble. The potential problem is how easy it is to disassemble and re-assemble it. Some are held by screws, some clip together (metal or plastic) others are not designed to come apart. You will hae to look at the clock and work it out. Use isopropyl alcohol on a lint free cloth to clean the strips and contacts. Don't get them soaking wet. If you don't want to DIY, I'm happy to have a look to see if it's possible if you post the clock to me.

Bumping yet another thread (hoping OP @Millmoo got the clock sorted)!

The clock is working, but the digits are slowly drowning in a water(?) stain, and the clocks are not all that easy to come by nowadays (and prol. even more difficult in the future)... Has anyone braved it out and tried the "disassemble the circuit board, LCD and zebra strips, clean and re-assemble" of the 181528380/181528370/719305614-clock as suggested by @g8rpi? I don't have a spare, so it would be really nice to get some inside info before considering taking the plunge...?!
 
Uodate: I managed to source a second hand Uno clock, off of eBay.co.uk and it's still working well 7 years later. 😉
Can't help with the rebuild sadly.

If the display is "bleeding" with distorted segments or dark areas creaping in from the edge it is not repairable. It needs a new LCD. Cleaning the zebra strips can only fix missing or dim segments.

In 2017 there was a discussion in vintage digital watch circles, that "massaging" the LCD screen, affected by bleeding, had a 50/50 chance of saving it. Don't know if the method actually works, and sure don't know how difficult it is to dig out the screen from the Fiat clock... Here is a YouTube clip on a vintage-watch-guy successfully trying it out:

Any comments @g8rpi?
