This Pioneer SX434 has come in with TWO Faults.
1. It will not eject the cartridge
2. It will not play any CDs
Tests confirm both faults. The cartridge ejection problem was a broken latch lever pivot and the non-playing of CDs was the usual one for these units, the objective lens in the optical assembly had fallen out.
Repairing the lever pivot was easy enough, except getting at it being the main problem.
Luckily the objective lens had got stuck somewhere in the unit and once found was cleaned and reinstalled using nail varnish to hold it in place.
Once completed and the customer's CDs were cleaned, the unit functioned perfectly, playing all discs right out to the last track. Apologies for the occasional stuttering cameras. All fixed now.
