Digital Clock (round 2): Loose Solder Joints

Last year I attempted to fix the clock. I tried stretching the springs out and cleaning the contacts, it did nothing. I got the radio replaced shortly after and the clock started working again... for 12 hours before it went away again.

I've had times when I got a jolt driving on the highway and it knocked the life back into the clock again only to go out 30 minutes later.

I saw another thread on a 4runner forum where someone said that the issue was with the solder joints cracking and losing continuity. It would explain why my clock can sometimes start working when I drive (a rare occurrence). But theirs was from a later sub-generation and some people said that Toyota made small changes to the digital clock between certain years.

Has anyone tried re-soldering their digital clock?

Are there any meaningful differences in the clock modules between the model years?

Almost not worth messing with it if this guy will rebuild it for you for that price. He claims to reflow the solder in the description.
