Gpx CD boombox won't play radio. Just cd - GPX Audio Players & Recorders

SOURCE: Emerson PD6810 CD Boombox Error

My older model PD6810 had the spindle that holds the CD on the player missing causing the ER message to show and the player to stop working.

You will need to use the Forward and Reverse buttons on the CD player. Set the station by holding the button you want to set it to until it blinks and shows the station number.
To set more that 10 stations. Press the (>10) button and then enter 11 or 12 or so on and set the stations the same as above.

First place to start is making sure that the lense is clean

The laser is dead or damaged. Try swabbing the laser with rubbing alcohol on a Q-Tip, then IMMEDIATELY blowing dry with canned air. If this fails, the laser is dead. If it is a Sony KSS-2xx series laser (try to peek in the laser slot to see the decal on it) you can get replacements online. If not, it's junk.
