Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
Sony | STRVX750 | AUDIO CUTS OUT | After unit warms up, SP relay kicks off. | ||
Sony | KV2681R | DEAD, REPLACE T-501 AND Q-504 | Unit was dead due to one leg of T501 was shorted to groundwhich in turn took out the H. output transistor. | ||
Sony | KV2680R | RASTER BUT NO AUDIO/VIDEO, IC1109 SHORTED ON "X" BOARD | Unit had raster out, no video nor audio, and R1247 wouldshort out at turn on. | ||
Sony | KV25XBR | MARGINAL FAILURE OF IC651 REGULATOR MODULE | Dark pix (customer complained of no video, however video isdiscernable when pix contrast is maximum), 90% raster (horizontal width),audio OK. | ||
Sony | PSLX510 | INCORRECT ASS'Y NUMBER | Could not locate part number for stator assy. Found on page27 the assembly is numbered 129. It should be 126. -HQ COMMENTS: Will issue a T/N and S/B. | ||
Sony | XRM10 | VERY LOW, YET UNDISTORTED AM BAND AUDIO LEVEL | Audio OK coming out of AM IC, but would not pass thru C-60 onAM PC board. | ||
Sony | CFSF11 | NO RECORD | Pause is engaged before record. Indicator lights but recordlinkage is not engaged. The record trigger lever is jarred off recordlever A (see P.10 of the supplement #1). -HQ COMMENTS: Replacement of forward lever is necessary. The problemcomes from th | ||
Sony | SL25 | NO P/B OR F/F FUNCTIONS | No F/F mode at all. Would enter rewind mode whenever the P/Bmode was entered. The sensor leads resistance would change from 4 ohms to20 ohms whenever the leads or the PC bd of the sensor was agitated. | ||
Sony | KX2501A | ALL BLUE RASTER, RETRACE LINES, VERY LOW VIDEO LEVEL, Q1302 | CRT raster was all blue with faint retrace lines and very lowvideo level. We were unable to reduce the blue level with CRT or bright-ness controls. DC voltage checks allowed me to trace problem to a leakytransistor, Q1302 on BD board. | ||
Sony | KP4600B | NO GREEN VERTICAL SWEEP | With set on, there was no green and display bar (which wasblack), rolling vertically. System looks like a problem in the picturetube area, but found no green vertical sweep. With loss of verticalsweep, there is no horizontal line, because itclue was th | ||
Sony | SLHF300 | NO POWER | Unit would not power up. Replaced IC301 (timer) but IC wouldnot reset, so problem was not resolved. | ||
Sony | D5 | BLOWN TRANSISTORS AND IC (SLED CIRCUIT) | Unit was brought in for service due to defective sled motorgears. Upon inspection, we discovered that IC508 and Q502-505 were burntseverely. The chip transistors disintegrated. IC508 is cracked and brownin color. | ||
Sony | BMC550 | INCORRECT P/N PAGE 148 | Typo in manual, Page 148. -HQ COMMENTS: Correct P/N SK-3 board (complete) A-7060-078-A DS-10 board (complete) A-7060-098-A DS-10 board part number is correct on Page 175 in the S/M. | ||
Sony | KV2602 | ONLY TUNES LOW CHANNELS, REPLACED NON SONY Q008 | VC voltage at tuner would only go up to 10VDC. | ||
Sony | TCFX505R | CONTROLLER CHIPS DIFFERENCE | When ordering IC501 and IC505, TC #9310N-032 (8-759-201-86)and TC #9310N-033 are sent instead of -021 and -022. The serial # showsthe unit falling into the former type but ICAlso fiche crosses to the new numbers. Are the two compatible? -HQ COMMENTS: |
