sc 811 2 problems

[nissan]

Hello everyone.
I'm in the middle of preparations to replace the dashboard of my car (850 94).
As part of the project I want to restore the original car stereo.
I got a SC 811 that works great ,but has two problems.
First. The lighting in the Display does not work (other lighting works great)
Two. The volume knob is missing. There is only a tiny round rubber.
I took apart the system to see if there is a bulb replaced in the Display, but the Display was welded and did not see where his light bulb. I'd love guidance to fix the lighting.
I'd love to know where to get the dial of volume?

There is a metal frame around the display that has tabs that are twisted and soldered to the back of the display PC board. On some it is only soldered on one tab and on others I've seen it is soldered on all 4. At any rate the frame needs to be removed to get access to the lamp. The lamp is soldered onto the PC Board. For replacements I have been using pn 272-1092 from Radio Shack. The blue filter doesn't fit tightly around the lamp like it did on the original but a dab of glue will hold the filter in place.

The knob is a tough one. It isn't available as a separate part from Volvo so a Pick n Pull junk yard is your best bet. If you need some other stuff they will likely toss it in for free since they won't know how to price it anyway. If they get all crazy and want to charge you over a couple of dollars for it PM me. I have an SC815 that I have been picking parts off of and I should have the knob around here somewhere, I just can't seem to find it at the moment.
