error code E20 for CD player
Fix for error code E20
Error code E20 occurs when the CD'* laser can't focus due to a dirty lens.
My 2002 Pontiac Firebird Trans Am'* Monsoon CD would only play commercially made CDs. It used to play CDs I made at home with my desktop but suddenly stopped playing them altogether and an error code E20 would be displayed before ejecting the CD. This is because CD players have a harder time reading privately made CDs, and my CD'* lens hadn't been cleaned since I bought the car 11 years ago in 2002 .
I removed the Monsoon from the dashboard, removed the case, motherboard, control board and last of all the CD player. Once removed, access to the CD'* lens was easy. I cleaned it with isopropyl alcohol (rubbing, NOT drinking, alcohol) and a cotton swab, or Q-tip. After reassembling everything, the Monsoon plays any audio CD once again and no error codes.
pro - $500 savings to replace, or do without privately made CD'*
con - 2 hours to do
