| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | CPD17SF2 | DEFECTIVE HORIZONTAL OUTPUT TRANSISTOR Q507 | 3 units came in with same problem, defective horizontaloutput transistor Q507 872982107. | ||
| Sony | CPD17SF2 | SHUTS OFF AFTER 2 SECONDS | Monitor will shut off after 2 seconds. Found 12V DC out ofregulator IC602 low (about 6VDC) Troubleshoot to hybrid IC PM501. Pins 1& 2 were shorted, which caused overload of IC602. | ||
| Sony | CPD17SF2 | SHUTDOWN; POWER & SAVING LED FLASH; GEOM LED ON | Unit shut down after HV came up. Power and Saving lightswere flashing. Geom light was on. Found Q510 almost shorted (about 200Ohm). | ||
| Sony | CPD17SF2 | FAINT VERT. LINES CENTER & RIGHT SIDE PICTURE | Two faint Vert. lines. Looks like drive line but it is 2from the right side. The other line is in the center but is waveshaped. We verified this with another unit that was in the Westwood SSC. | ||
| Sony | CPD17SF2 | UNIT DEAD | Unit dead, no lights. First check shows Q507: H. Outshorted. Replaced Q507 and unit has HV. But, unit shuts down, Save andPower LEDs flash, Size light on. FBT T501 Pin 11 has about 3V, should beabout 10V. IC901 pin 18 is below 2.6V. Found D596 lea | ||
| Sony | CPD17SF2 | DEAD, PS IC FAILURE | Monitor was dead. | ||
| Sony | CPD17SF2 | DAS DOES NOT SHOW HV SHUTDOWN | Unit was in high voltage shutdown. Proper LED was blinkingto indicate HV shutdown. Das did not indicate problem. Everything elsewas normal for set in HV shutdown. | ||
| Sony | CPD17SF2 | MISSING COLORS OR NO PIX DUE TO VIDEO CABLE | Short section of (partially rigid) RGB cable betweencomputer D-SUB 15 connector and in-line noise filter is flexed and bentcausing loss of color. Bent wires pulled loose inside the D-SUB 15connector. Cables on 2 units showed signs of being pressed bet | ||
| Sony | CPD17SF2 | D BOARD MOUNT HOLE CRACKS | D board has stress cracks in and around the two screwmount holes on each side of the board. One hole is next to R620 and theother is next to R496. Also applies to S/N 2108587, 2103926, 2103924,2108593, 2108592, 2103927. | ||
| Sony | CPD17SF2 | MAIN BOARDS BREAKAGE | Main board has a star type crack at 2 screw holes nearQ401/Q602. Cracks appear to be from screws being tightened too much atfactory. SN 2102538/2103925/2103929/2108588/2103923/2103928. | ||
| Sony | CPD17SF2 | ON SCREEN DISPLAY STUCK ON | Unit had Size display on screen. Would not go off when anycontrols were pressed. IC901 Pin 16 voltage read about 3v instead of 5v. | ||
| Sony | CPD17SF2 | UNIT DEAD, FRONT PANEL LED OFF | Unit dead, no light on front panel. Check IC601. OutputPin 14 has no output waveform. IC601/15/16 have about 11v. C609 has 168V. Unplug power cord and positive side of C609 is still at 168V. | ||
| Sony | CPD17SF2 | UNIT DEAD | During troubleshooting, measured C609 voltage at 168 V evenwith power cord unplugged. To see if IC601 is working, opened output pin14. Lifted gate of Q602 to check waveform. Unit burned Q602, IC601, andT601 very quickly. |
