Toyota Repair: Changing dash illumination lights, illumination lights, light bulbs

Question
I want to change the light bulbs that illuminate gauges and controls on my 1988 Camry sedan.  The only ones still working are the one behind the speedometer and the LCD on the radio, so I think it is time.  I have the 1988 Camry shop manual from Toyota, but I don't see instructions for changing bulbs.  Can you please either tell me how to do it or refer me to the documentation on the subject?  Thank you.

Answer
The instrument cluster can be removed from the dash,first remove the screws that attach the trim piece in fornt ot the glass then remove the fout 10mm screws that are on the cluster, disconnect the speedo cable at the back and the electrical connectors, all illumination bulbs are on the back and can be removed and replaced.
