Release the four hidden clips to remove the panel.
-
This might require a lot of jiggling and prying.
-
-
-
-
Unclip the four clips to remove the back cover.
-
Get three prying tools and insert them into the clips to allow that side of the case to be removed.
-
Unclip the last remaining clip to fully remove the case.

-
Check the solder points on the resistors.
-
R300
-
R510
-
Touch up any solder points that look like they may not have a good connection.

Test the repair before reassembling the clock assembly by plugging the electronics into the dash.
-
Turn the ignition to the
2
position to get the clock to display the time.
>>>Test the repair before reassembling the clock assembly by plugging the electronics into the dash.<<< Mine Started "Letting the Smoke Out" Tested on Bench Power Supply for very short duration. When I Connected to Vehicle Wiring...Smoke! Maybe I overheated a very small Diode? Test the repair before reassembling!

Thankyou,
This worked awesome..Quick easy..Now i know what time it is again..
510 was so loose it slide off the board after I tapped with a pencil. Did my best to line it up and touch up the solder. No luck. Junkyard for a new one....sorta new.
This worked perfectly for me! I saw one resistor clearly had a bad solder joint and I resoldered it. The others looked alright but I hit them while it was open (with the exception of the side of 510 under the display which was hard to reach) and now the clock works like a charm! :D Thank you!
The clock on my 99 crv has played up couple times over the years and I have had to resolder those three main resistors like explained in this procedure. But lately it was playing up once again and it finally went dead other day. You need to check the solder on the resistor underneath the screen also, its the one labelled R203. This requires the desoldering of the two points on screen to allow you to bend the screen up and get underneath. Bend the screen up a little resolder R203 and solder back the two metal legs of screen into the board. Good to use a multimeter to test the resistance across each resistor once soldered. If you dont measure any resistance the solder has not been performed properly. Also test the circuit once complete from the connection points to confirm there is a complete closed circuit loop.
Kev……. do you have any pics of how / where to de-solder the screen?
Kevin Wagner: unfortunately I've already reassembled the clock and reinstalled it but I'll try to explain. The circuit board is clipped into the beige shroud in two places: carefully unclip it so it comes free. One side of the display has a bunch of pins passed through the board- just ignore that. The other side has two pairs of solder joints passing through the board. These are the ones you need to remove. Mine were bent over after being passed through the board but I just heated both joints on one side and slowly pulled until it was free. Then I did the other side.
Before I slid them back into their joints I straightened the bent pins with some pliers so they'd slide in easily. A bit finicky but only adds a few minutes to the procedure. Hope this helps.
How to change from 4 wheel drive to 2 wheel drive ? please help
awesome, fixed, clock works now!
Brilliant. I am not handy, and with these instructions, even I could fix our clock (that had ceased to work at least 5 years ago). Thank you!
Resistor 510 completely came loose on one side when I checked it. Luckily it was on the side that wasn’t under the screen. Resoldered, plugged it in. Worked like a charm.
I’ve double checked the 2 areas you identified above and made some repairs. The clock will work for a few minutes or more, then for no reason go blank. Tapping clock or dash seems to have no effect. Occasionally it will come back on of its on will. Any suggestions on what could be causing these intermittent problems?
İ tried and it works, you can remove the panel with a credit card or something else

All connections look to be solid but clock still won’t function.
Awesome! Took me about ten minutes to complete, and that includes desoldering one side of the display to get to the 230 resistor hidden underneath. I'd recommend doing this to be sure you've covered all the bases, and it made soldering the far side of the 510 resistor much easier. Definitely do be careful about removing the shroud from the dash: I wasn't patient enough and snapped three of the four clips off. Luckily it reseated nicely but it's better not to bust things unnecessarily.
Still working in 2021! Had a little more trouble removing the panel but got easier because I have no radio at the moment, so I was able to push it forward with one hand and releasing the clips with the other. Couldn’t believe how bad the solder points were.Thanks for the help. (Honda CRV 1997).
This worked perfectly for me. The dash clock in my 1999 Honda CR-V had been dead for months. The solder joints on all three resistors had cracked.
