| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | CDXT62 | WON'T EJECT MAG. (FOUND 1 SPRING SET vertical, 1 HORIZONTAL) | Unit would not eject magazine. Controller said No Mag. | ||
| Sony | SLV940HF | PIX UNSTABLE ON SELF RECORDED PB (B/W vertical BARS)-IC351 | Pix is unstable in PB self recordings (will go to B/W bars). | ||
| Sony | KV32V16 | vertical JITTERS, RE-DRESSED LEAD WIRES | vertical jitters, pix jumps. | ||
| Sony | KV20M10 | vertical JUMPS, REPLACED TUNER | vertical jumps, found video signal from tuner pin 18 was too low, 1/2 volt. - | ||
| Sony | KV32XBR45 | vertical OUTPUT FAILURESR553 & R554 | Unit was fixed twice by local dealer, vertical output IC wasreplaced both times. Unit came back again due to failed IC501.Found IC501 was running hot, but pix had no distortions. Furtherinvestigation showed small decrease in 15v lines. | ||
| Sony | KV32XBR37 | INTERMITTENT ON/OFF WITH vertical LINEARITY DISTORION | Unit intermittly did not come on. When it did itdisplayed poor vertical linearity. | ||
| Sony | KV32XBR45 | NO vertical DUE TO NO 5V DC SUPPLY TO MICRO, REPLACE D613 | Unit came in with no picture or sound. Discovered that itdid not have vertical deflection. All data lines were low. Between 3and 3.6V p-p. Nothing was loading them down. Found shorted diode D613on open resistors R623, 624 and 625 in 5V set line. | ||
| Sony | KV27S10 | INSUFFICIENT vertical, YOKE | Picture pulled up about one inch from bottom. Adjustingcontrols allowed picture to fill out but centering was off. Whencentering was adjusted picture folded over. Replacement of yoke resolvedproblem. | ||
| Sony | MZE2 | DIFFICULTY LOADING/PLAYING WHEN vertical | Found 3 units which had difficulty loading and/or playingdiscs when the unit was in the vertical position. Problem appears to becaused by dead spots on the sled motor (M902), which causes the motor tostop working when more driving force is needed. | ||
| Sony | KP46V15 | NO vertical, IC907 | There was no vertical deflection. This was a result of the-5v and +5v lines being very low. The problem was caused by IC907. Itwas shorted and drawing too much current from these supplies. Replacementresolved the problem. | ||
| Sony | KV27XBR35 | PIP ROLLING verticalLY AND SHUTDOWN, ROSOLDER Q323 ON E1 BRD | Intermittently, pip started rolling vertically, few secondslater pip and main picture blanked, another few seconds and shutdownactivated. Pin38 of E1 board had no vertical pulse which provides syncto P1,P3, M and E2 boards. Found cold solder Q323 col | ||
| Sony | KV27S10 | vertical DOWN ABOUT 2 IN FROM TOP, REPLACED R539 & IC101 | vertical was down about 2 from top. checked voltage on TP98and read 1.8v. Tech determined to be FBT. Replaced FBT with sameproblem. Checked another set and TP98 should be 11.8v not 15v asschematic states. Traced problem to R539 had changed value from | ||
| Sony | KP61XBR38 | NO vertical SWEEP, REPLACED C1713 SHORTED | Set had no vertical sweep. 3 color lines across center of screen. F902 was blown, sub deflection IC's checked good found 15v missing. IC 905 getting very hot. | ||
| Sony | KV29XBR85 | PICTURE SHRUNK verticalLY,NO MEMORY, REPLACED D7009 | Set came in with picture reduced from top, keystoen shaped.Enterend service modek, changed setting to bring pic back to noarmal .Write settings to memory. Set would function normally. Removed power,problem re-appeared, new settings had not been retaine | ||
| Sony | KV2084R | INTERMITTENT vertical, RE SOLDERED OPEN GROUND BY IF SHIELD | Intermittent vertical deflection. Very sensitive to tappingof the A board. |
