Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
Sony | KP5040 | PICTURE DISTORTION, SHIELD WIRE CONNECTION CHANGED | Vertical instability on channel 4 only. Also loss of verticalsync, deflection and excessive noise only on channel 4. This symptom hasonly appeared in Southern Connecticut. | ||
Sony | KP5040 | 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 | ||
Sony | KP5040 | NO CHANNEL LOCK, INCORREC IC001 | This unit would not skip channels or operate on UHF onchannels 83, 84, 85. The tuner switched back to VHF-low operations.We found the incorrect uPC installed. It was uPD553C-056. | ||
Sony | KP5040 | NO RED VERTICAL CONVERGENCE, REPLACED CRT NECK ASS'Y | The red vertical convergence does not move. Found open coilon the CRT neck assembly. | ||
Sony | KP5040 | 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 | ||
Sony | KP5040 | MECHANICAL MIS-OPERATION, LUBRICATED PISTON ARMS | Mirror would jam in either the inward or outward movement ofthe mirror. There was a hue shift in the center of the screen. | ||
Sony | KP5040 | CHANNEL DRIFT OFF STATION, REPLACED LEAKY C209 | After about 10 minutes, channel would drift off station.Found C209 had resistance. | ||
Sony | KP5040 | PARTS AVAILABILITY | Please investigate if the drive cords for the electromotivearms may be available as a separate part for replacement instead ofreplacing the complete arm assy which is so expensive. Refer to page 29of Service Manual. -HQ COMMENTS: The pipe side end of d | ||
Sony | KP5040 | POOR BLUE RESOLUTION, REPLACED BLUE CRT | This unit had poor blue resolution and some bleeding. | ||
Sony | KP5040 | 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 | ||
Sony | KP5040 | 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 | ||
Sony | KP5040 | 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. | ||
Sony | KP5040 | 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 | ||
Sony | KP5040 | SHUT DOWN, REPLACED HIGH VOLTAGE BLOCK | Door would not open. Unit would shut down. | ||
Sony | KP5040 | POOR FOCUS, REPLACED HV BLOCK | Unable to get a good focus. Problem traced to high voltageblock. |
