Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SONY | SL2410 | Intermittent play mode | Stop or p/b mode about 1/2 to 1 1/2 hrs. | ||
SONY | SL2000 | Unit will not work on battery power | Unit will not work on battery, but works with tt-2000. | ||
SONY | KV1512 | Picture dim | Picture is dim. does not have full width, horizontal. frequency. runs too high. | ||
SONY | KV1920D | Insufficient vertical deflection | Cannot get full vertical def. vertical distortion on thetop, about 1/2 foldover. | ||
SONY | SL5200 | No reel drive | No threading nor unthreading, rew, ff. | ||
SONY | STRVX550 | Intermittent output | Audio cuts off intermittently. sp relay kicks off. | ||
SONY | KV1356R | Intermittent shut-down, reajusted hold down circuir (r-541) | Unit shuts off on ch. 22. | ||
SONY | KV2670R | Improper brightness, r-526 and d-508 | Brightness and screen controls did not work. | ||
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 4Ω to20Ω 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. |
