RE: XJ6 95-97 CLOCK Please Read
Do a search and there are detailed instruction readily available (I thought I'd copied them into a separate document but can't find and too lazy to do the search all over again). It worked for me! You also need to remove the 'ski slope' to gain access to the radio..it is very easy.
I used a piece of pizza box rather than a business card, but it worked like a charm... first time. give it a shot... the dealer quoted me a price of $680 to replace with a new clock... I just chuckled inside and went home an repaired it myself.. great feeling!

Clock modules occasionally suffer from faint displays, caused by bad contacts
between a circuit board and flexible ribbon cable inside the unit. It is
possible to make a repair, though some may consider it to be a less than
professional fix!
Access can be gained following the instructions in section 10.1. Remove the
connector at the rear of the clock unit itself, undo the four screws attaching
it to the rest of the assembly and then take it to a bench area for further
work.
The unit itself is opened by undoing the small screws at the rear and releasing
the plastic tabs. Whilst the unit is open, take care not to lose any of the
small components in there. Release the LCD panel itself by carefully spreading
the black tabs holding it into the white plastic bracket. The panel is attached
to the main circuit board by a ribbon cable, and it is the connection at the
circuit board end that is the problem.
Tape the ribbon cable in place and use a business card or piece of pizza box (
both have been successfully deployed! ) to put pressure on the ribbon cable
where it connects to the pcb, behind the white plastic bracket.
Take the unit to the car in plug it in. Use the time set buttons to cycle
through all the digits to make sure the fix is complete before reassembly. If
segments are still missing or faint, additional pressure may be needed on the
ribbon cable.
When all is working, reassemble the clock unit and then refit into the centre
console. Attach the cable and take care not to stress any other wires as you fit
the console back into position.

Hi everyone. Im an electronics engineer in the UK and a Jag owner. If someone wants to send me their clock(nothing guaranteed) I'll have a look and see if it can be repaired and post results. Usually LCD's fading are caused quite often by the bulbs back lighting them causing too much heat. These man be replaced by white LEDs.
PM me.

Here is a place that fixed my clock 1995 XJ6. It looks better then original. $65.00 plus $15.00 for shipping and 5 years warranty. They did an exellent job. I love having my clock working and looking sharp the way they did it.

I did the shim repair for my 96 VDP with a bit of closed cell foam and got poor results, I did it again with a bit of thin wall corrugated cardboard as I would expect a pizza box to be and it worked like a charm. 6 months later and the digits are still showing perfectly. I guess you just have to use the right material, both thickness and compressibility.

The whole issue is about the ribbon making solid connection with the board. The flaw in the design still exists even if you use the cardboard/shim method or reaffix the ribbon. Those two bulbs located right under the ribbon get too hot. I have looked at a total of 8 to date. I understand that is in no way a broad enough sampling, but every single one had brown marks on the ribbon from the bulbs. Every one had heat damage that lead to the ribbon becoming loose from the board.
The way to repair the root of the problem is to replace the hot bulbs with LEDs. They are brighter and the additional glow may not appeal to some purists, but it does solve the problem and prevent further degrade of the ribbon.
I read an article, it was either here or JL or MotorcarsLTD or who knows, but it talked about an adhesive that was intended just for this purpose. I cannot imagine which adhesive would not interfere with the conductivity, but apparently there is one.
We really ought to be able to put our heads together and come up with something better than a "pizza box" fix.
Peace!

The adhesive is a special one that includes conductive particles that are large enough to provide connectivity from the ribbon to the glass, but sparce enough not to provide conduction between the ribbon conductors. It is not something you would find in the hardware store. 3M is an industrial supplier, but I did not contact them directly to purchase some.

Do you know the 3M part number, or name for the adhesive? I never liked the pizza box solution for any reason other than it worked. Leave it to 3M to come up with a brilliant product like this. (I did not notice any discoloration of the the ribbon on my 96 VDP. Perhaps it is routed slightly different. I will have to look at how close it is to the bulbs if I can get the adhesive and redo the affair.)
