| Sony | AE-5 KV32FX60U | int. pic would flick off for a split second | incorrect factory settings, enter features menu and switch auto format to OFF, enter setup menu and switch AV1,2,3 to OFF | 14-09-04 |
| Sony | AE-5A KV36FS70 | stuck in stby | IC6654 KA78R05 5V regulator on D PCB | 14-09-04 |
| Sony | AE1 | Blank screen with flyback lines | R805 ( 1R2 ) o/c | 14-09-04 |
| Sony | AE1 | Blank screen, no tuning memory when heated | Memory chip IC003 (M58655P) used in AE1 chassis requires -30V on pin 2 to operate. If -30V is lost, no station memory - check L807 for o/c in LOP when warm. L807 used as voltage dropper to reduce volts derived from transformer & its inductance (10mH) is important. It should always be replaced with original part, otherwise damage will occur - part no 1-407-504-00. | 14-09-04 |
| Sony | AE1 | Burning smell | Dry joints R614 - can fit in alternative posn; check R611 & L607 for o/c | 14-09-04 |
| Sony | AE1 | CAN'T STORE STATIONS PIN 2 ICOO3 NOT -33v | L807 OC PtNo 140750400 also check R008 C017 | 14-09-04 |
| Sony | AE1 | Chans won't store - int | The -30v supply to IC003 M58655 Memory chip falls to -15v. L807 feed coil was int o/c | 14-09-04 |
