RCA CDRW121 home cd component unit .
Problem . The record side takes the disk , spins it . It makes a series of mechanical clicking sounds , quiets then repeats that 4 or 5 times then displays ``no disk`` The play side of this 2 tray unit plays fine . What i have done. Removed the CDR unit . Cleaned the lens and glass piece under the lens ( much like cleaning a ps2 ) Checked the plastic gears and pulled & reseated all cables in it . Tested voltages as marked on the power supply board plug going to the CDR . Questions . Would it be the circuit board in the cdr drive or the laser assembly or which one should it be more likely ( probably a dumb question ) Would a CDR drive be avaiable for this . It looks like standard computer type plugs on it . And the cost of the part-s ? Thanks |
