INTERMITTENT MECHANICAL OPERATION, REPLACED IC6502 N S953 Intmt operation of the mirror assy which was not related tothe load on the motor/mechanism. The tubes were lubricated and movedfreely, mirror was removed. Actually the voltage to the motor droppedfrom normal 25V close to 0V and the motor would coast to

VERTICAL LINE IN THE CENTER OF THE SCREEN Vertical line in the center of the screen from cross hatchgenerator. Lifted resistor's R3393 and R3384 and connected them to BA-9Pin 2. This method of getting RD of the vertical line is better thanjumping a capacitor across D3312. With the capacitor a

TEST SIGNAL INTERFERENCE, R3383 AND R3384 CONNECTION CHANGE I have two KP-5040s with cross-hatch interference on weaksignal stations - cures suggested in FPRs have not helped. If I liftR3383 and R3384 from the 12 volt line and jump them to Pin 2 of connectorBA-9, and thereby remove voltage from the horizontal cr

POOR FOCUS, ADJUSTED ELECTRICAL AND MECH. FOCUS Distributors complain of poor focus on KP-5040. A littleblurry was traced to the acrylic lenses, which are transmitting a slighthalo around well defined objects. Noticeable around the blue cross hatchbars, which causes them to appear wider than the oth

WRONG PART NUMBER, R818 Resistor R818 on E board is shown as a 3.6 ohm resistor onservice manual schematics. It should be 3.6 kohm. Parts list in rear ofmanual is correct.
SonyKP5040
INCORRECT MECHANICAL FUNCTION When closing mirror assy, motor stops intmtly during first 3or 4 inches of travel. This is more severe if even the slightest pressureis applied in a downward motion on the reflector when motor is running.The plastic pipes tend to jam severely when press

POOR FOCUS, REPLACED HV BLOCK Unable to get a good focus. Problem traced to high voltageblock.


Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
