| Sony | KV27TS36 | vertical JITTER AT TURN ON, REPLACED C334 ("M" BOARD) | Set had severe vertical jitter at turn on, but wouldoperate normaly after a few minutes. ASC located a bad capacitor C334off IC301/pin 32 on the M Board. Capacitor checked good, out ofcircuit, but was heat senitive in circuit. Replaced with exact replac | ||

ASC LOCATED BAD CAPACITORC334 OFF PIN 32 IC301 MCB A. CAPACITOR CHECKED GOOD OUT OF CIRCUITBUT WAS HEAT SENSITIVE IN CIRCUIT. REPLACED WITH EXACT REPLACEMENTAND SET OP | ||
| Sony | KV27XBR10 | NO vertical DRIVE FROM IC301/PIN 31, REPLACED D253 AND D252 | Missing vertical drive from IC301/pin 31, on the A Board. | ||
| Sony | KV32XBR95S | vertical DISTORTION, REPLACED IC1501 (VERT OUTPUT IC) | Transparent horizontal line through the middle of thepicture, with small amount of fold over at the top of the screen. Theproblem occurred after 10 minutes. Applying freeze spray to the verticalOutput IC1501, would cause the problem to disappear. | ||
| Sony | GDM2036S | PICTURE STRETCHES verticalLY DUE TO IC-201 | After warm up, the picture will start to stretch vertically atthe bottom. Customers says it would take anywhere from 1/2 to 2 hours.By heating and cooling IC-201 I was able to produce the problem. | ||
| Sony | SSM721AMR | NO, OR INTERMITTENT vertical SYNC, RESOLDERED C513 | There was either intermittent or no vertical sync. C513 wasnot soldered correctly which caused it to become loose and makeintermittent contact. | ||
| Sony | KV1380R | vertical ROLL, REPLACE C230 | I received a unit from an authorized servicer with a verticalroll. He already tried a new jungle IC with no change. After verifyingthe problem, I fed video into Video input and found that it workednormally. Looking at the V sync pulse and comparing vi | ||
| Sony | SLV585HF | vertical BAR DISTORTION: REPLACE THE FULL ERASE HEAD | vertical bar distortion on the video picture. | ||
| Sony | KV27EXR95 | vertical COMPRESSION, REPLACED C-547 (A BOARD) | The picture was vertically compressed at the top. The problemwas caused by C-547 opening up. This capacitor decouples the -15V line.Replacement resolved the problem. -HQ COMMENTS: C-547 is located at IC-500pin 4, schematic grid locationH-19. | ||
| Sony | CCDFX510 | vertical ROLL IN PICTURE | Picture would roll vertically in viewfinder and video output. | ||
| Sony | GDM2036S | NO vertical DEFLECTION | Unit has no vertical deflection. Checked and found openvertical Yoke. Tried to locate the open, and found C01 on the Yoke ass'yopen. The coil is made up of large wire, so it cannot be defective. | ||
| Sony | GDM1936 | NO vertical DEFLECTION | Unit has no vertical deflection. Checked and found openvertical Yoke. Tried to locate the open, and found C01 on the Yoke ass'yopen. The coil is made up of large wire, so it cannot be defective. | ||
| Sony | KV27XBR50 | NO vertical LOCK WHEN COLD, REPLACED C-1345 (B BOARD) | Picture would not lock vertically (roll) when cold. Oncewarmed up, picture would have vertical jitter intermittently. |
