I've noticed the clock on my new CB7 is only working sometimes and keeps resetting. Decided to take it out and have a look, here's a little write up / diy.
Firstly I'll show you how I removed the clock, it can be a bit tricky when they're so old and brittle.
I pried the clock out by putting my fingers on the inside and pressing out towards the two sides for grip whilst pulling outwards at the same time.
It popped out a bit, juuuust enough to get a grip on the outside edges.
Note: I wouldn't recommend trying to lever it out with a screwdriver in between the clock and the dash. The plastic can crack very easy and you can permanently mark your dash! If you really get stuck, try using a spudger
Try levering the sides, thats where the retaining clips are, levering at the top and bottom isn't going to be very effective and DO NOT lever the corners, these are the most vunerable parts to chip and break off.
Moving on hopefully you've been successful so far in getting the clock to pop forward enough to get a grip on it.
What I do now is focus on getting the left hand side to come out, reason because the plug and wiring harness are on the right hand side so Left is going to be easier. Without too much struggle the left clip came free and it came out a bit more, now instead of trying to pop the right hand clip loose I found it easier to keep pulling the left hand side out and take the clock out sideways.
I mean when you do this you're gonna do whatever feels natural, this is just how I did it, im going into quite a bit of detail here just because it can be quite delicate to get out without damaging anything.
So once you have the clock out, you can remove the plug and begin the repair.
Stage Two - Fix dodgey clock
So I took the clock apart - its only 4 screws no need to go over that, and had a good look at the circuit board.
At first glance it looked fine, no burned out parts or water damage or anything like that but I wiggled the connector socket and it moved a bit, I had a closer look at the solder joints and sure enough the G (Negative ground) had a dry solder joint.
So If you know how to solder then you know what to do from here. If not its pretty easy theres loads of tutorials on youtube, I re-soldered all 4 of the connections just to be sure..
Tested and working fine!
Then all thats left to do is put it back together and re-install into the dash, shouldnt need to walk you throught that its fairly straight forward.
Voila now have working clock again.
