I have a 1995 LS400 the CD changer in the dash. Today I took it out, it was only playing Cds now and again after using a CD cleaner I found it had packed in and would not play any CDs. The CD cleaner had moved the dirt over the lense and made it worse. I took off the two covers, that lets you see inside and you can then see the lense and clean it with a cotton bud and the lense cleaning fluid then a good wipe off with dry cotton bud Put it back and all is well Spot on I would say it is a 45 Min job PS I was an RAC patrolman for 16 years so may be it is an Hours job.
