By opening up the radio you will find a narrow display power board
within the left side of the radio (faceplate toward you). This board
has a metal cover soldered to it, with a toroid (wire wound doughnut)
inside on one side, and a bank of surface mount resistors and capacitors
on the bottom side. One end of the board (SCR heat sink) is screwed to
the heat sink at the back of the radio, the board is secured with 2
metal bend-tabs, and it has a white mini connector on the other end
which connects to the faceplate. Remove the board from the radio.
On the bottom of the board look for surface mount components
R1057/C1071/R1058/C1083/R1064. The colder these resistor/capacitor
chipsets get, the brighter the display. I left the car out in the +5 f
degree weather and the display worked until it warmed up a little. That
is how I was able to track it down to these temperature sensitive
parts. Freeze-it also helped after I narrowed it down to a few
components.The fix that worked for me was to re-molten the solder for each end of
these surface mount components. Be very careful if you try this, as a
big soldering iron, or a lot of heat will destroy the components and
board. And don't do this with the radio plugged in. If you're not
comfortable doing this take it to a friend who is.
