Any ideas how to fix the $250 Toyota 4Runner digital clock?

Over on the Toyota forums, people rewire the Toyota digital clock circuit
board for free!

It's a very common problem with Toyota.

There is also a $30 service that will re-wire the clock for you.

But since you posted in a.h.r, you should be able to solder the circuit
board yourself and you get four solid genuine silver springs for free out
of the deal!

There is fundamental physics behind the fix. I've fixed a toyota
clock, an
Hp calculator and bike speedometer that way. Circuitry must be CMOS.

The experts at sci.electronics.repair do. How about ToyotaNation.com?

I'd check solder joints and electrolytic capacitors. Clocks have one
voltage regulator for the logic, and it could be a 5V linear one or a
switching regulator. The display uses either high voltage DC for
fluorescent displays, a low voltage (roughly 15V) AC source for LCDs.
Any switching regulator can have electrolytic capacitors wear out.
Replace them with Japanese ones from Mouser.com, BDent.com, or
DigiKey.com.

The problem was the power connection is flaky.
I removed four silver springs.
I then pulled the pins off the harness connector.
I soldered those pins onto the Toyota digital clock circuit board.

When I put it all back together, the clock magically works now.

Here's the DIY I followed.
