Car radio will not play when car is cold

I know this is a car question, but it is also electronic.
I've asked this question in car newsgroups but haven't had any answers yet. I thought I'd ask the experts here :)

I have a 91 Tbird with a factory premium sound cd player/radio. It will not play until the car is warm inside. The clock will not display either until the radio works.
To get the radio to play I have to restart the car after the interior is warm. I have to drive about 12-15 miles with heat on full blast then, if on expressway (which is the case on the way to work), put it in neutral, turn it off, restart it and put it back in drive. This can't be good for the trans.
Is this no play cold radio thing a common problem?

Yes, I know. I can hook up a test light or voltmeter to the power wire where it goes into the radio to check to make sure it is getting power when cold. I haven't had time nor would I know which wire to hook it to.
This is possibly an ignition switch problem as well.

I would like some insight before I start shooting in the dark at this annoying problem.

Any thoughts?

The only way to fix this one is to remove the radio and bench troubleshoot
it for thermo problems. It may be a simple generic part that has become
thermo sensitive. Electrolytic caps are known to give these types of
faults.

You can use a heat gun and freeze spray to troubleshoot this one. It should
not be too hard to do, but can be a bit tricky to zero on the right part(s).

My 91 Ford pickup had this problem with volumn. The advice I got was to
check the soldered connections around the
volumn control. I did that and found bad solder connections. Heating
them with the iron fixed the problem.
