FE2
|
Reverts to st/by at sw on with 2 or 5 flashes from led | 5 flashes indicates an akb error (grey scale correction). this is normally due to lop shut down & tsound is no eht or sec line volts. normally due to faulty r618 (270kΩ). this res is in the current sensing cct & could tsoundfore potentially give you an over-current error (2 flashes). | ||

Image becoming very white, varying over time | The t-con board was replaced, but it did not solve the problem. On the screen board there was oxide from the resistor r10 30c (20kΩ) and it was open. | Replaced it with one with the same code that was taken from a faulty screen, and then the trimpot was adjusted to the value of 6vdc | leitemarcellus |

KLV32S301A
|
Does not arm the power supply | Change the power supply board which is together with the inverter | Replace the power supply board that comes with the inverter and good luck | DAVI DE PEIXE-BOI |

SLV-757
|
Noise ascending on screen constantly and very bad hi-fi tracking. | A polarized surface mount capacitor in capstan motor pcb. its a 22uf 16v polarized capacitor turns to be the cause. (no measurable capacitance). i used a 47uf-25v standard axial electrolytic type with good results at lp and sp mode. | ||

Deck eject cassette if rewound to leader tape. | S1-rotary switch dirt inside. possible bad contact. part nº. 1-571-920-11 | Remove it carefully , open it and clean very well. assemble it and mount it again. pay attention to gears marks positions - dot on s1 gear and arrow on rkb cam (art 3-736-170-01).check position of pendulum arm. mine serviced s1 fails after some work on the same function. probably a newer s1 rotary switch is advisable. | |
