Light Out in LCD Stereo/CD/Cassette

Post by markdp33 »

The light is out in the LCD Display in the AM FM Stereo/CD/Cassette so we cannot see the display at night. 1999 Volvo S70. Are there bulbs someplace inside the stereo? Are they replaceable? Its dangerous to fumble around at night to check the channel.
Help!!!

Yes, there are bulbs inside the radio. If it's an 815 or 816 model radio, try these steps:
1. Pull the radio partially out of the dash (unhook the wiring). Take inside to a well lit area. Remove the screws just behind the face plate on both sides of the radio chassis (4 screws total).
2. Remove the equalizer, fade buttons and tuning/volume buttons, they should pull right off. (don't loose these, as the tend to "pop" off and land in hard to reach places)
3. Pry the plastic retainers just behind the face plate of the radio on the top and bottom of the radio chassis and then remove the face plate.
At this point, you will see a printed circiut board which houses the 6 lights we're trying to get at.
4. Remove the 3 screws the retain the circuit board, these should be at the lower center and upper corners of the board.
5. Carefully remove the circuit board from the radio chassis and pull straight forward. The circuit board is modular and slides into a couple of multi-pin connections, so be sure not to damage. If you have difficulty removing this, try prying gently with a small putty knife.
6. With the circuit board removed, access the lights from the backside by turning the lights 1/4 turn CCW. (you can used a small screwdriver, but you should be able to turn with your fingers)
7.After removing the bulbs from your radio, remove the old bulb elements from the plastic housing and insert the new bulb in it's place. This is tedious. Try to find the end of the wire and pull up on it. Or chip away the "glue" holding to wire leads in place and wrap the new wire leads in similar fashion. However, I was able to do this with just an exacto knife (be very careful PLEASE).
In a hour or so I had replaced all of my bulbs and should be good for another 50K miles. Please note that many owners (including myself) leave their headlights on all of the time, which probably causes the bulbs to burn-out sooner. I now keep the dash lighting at 1/2 brightness.
