ZMAN,
replacing the channel LEDs and the freq counter LEDs on a galaxy style radio is not impossible, but it is also not for the first timer.
the PC boards are double sided, plated through, and very cheaply made.
(look up "plated through" if you dont know what that means)
if you do not have a good desoldering tool (not the red bulb from radio shack), and know how to use it very quickly and efficiently; you stand a good chance of ruining the PC board for the displays.
if you are already very experienced at soldering and de-soldering delicate PC board traces, then the process goes something like this:
1. disassemble radio, front faceplate, and bracket.
2. gain access to both sides of the display PC board removing/unsoldering anything holding it in place.
3. using a soldering iron and desoldering tool (or desoldering station if you have the bread) remove every bit of solder from each of the freq counter LEDs and the channel display. the LEDs should all but fall right out.
if they seem stuck in place, DO NOT PULL ON THEM!!! you must desolder the pins again to make sure you got ALL the solder out of the holes.
4. put new LEDs in place, and solder.
5. change value of correct resistor in dimmer circuit for desired brightness level.
6.change lenses to correct color. (the stock orange lens in the 959 will make blue LEDs look green)
now, that may sound easy enough, but if you overheat the board, or pull one or more of the "plated through" metal cylinders out, then you are going to have to hack the radio back together, and you better be darn good at reading schematics/ diagrams.
bottom line, this job is usually best suited to those who are willing to replace your radio should they screw it up.
