Your advice is correct about the cold solder coonection. I'd resolder
everyhting and its working again in 2 years. I would have never attempt this.
You've figured it out for me. Thank you for your help.

Look for cold solder connections on all the connections and on the
circuit board. Also check for any parts being mechanically
intermittent.

My digital LED display on my 1988 Honda Accord works on a cold day but
dies on
hot day by failing to come when the ignition is turned on. Gently, I
bang
really hard on the dashboard then it comes alive until the next day.
I notice a four-watt resistor that runs really hot (could
almost
light a cigar) but I could trace voltages going all the way to the IC.
May the
IC lost ground? But how do we diagnose something when Honda doesn't
provide a
diagram. I like to fix this one because I have several Hondas with the
same
symptom. What If I use a functioning identical clock and take
measurements?
Parts are easy to find since I have a shoe-box filled stash of
these
clocks in my basement.
