| Sony | KV32XBR96S | LOW AUDIO LEVEL FROM VARIABLE AUDIO OUTPUTS WITH EXTERNAL SP | When using the variable audio ouputs to drive the SA-VA3(External Audio Speaker system), the speakers would return to standbyunless the volume level was increased beyond the customers preference.Not enough signal for vox control circuit in the SA-VA3 to | ||
| Sony | KV32XBR96S | GEOMETRIC DISTORTION AT BOTTOM OF PICTURE, REPLACED DY | Bottom of horizontal lines distorted. Overall purity and convergence has no problem. Readjustment improved problem only slightly. Problem resolved by replacing yoke. | ||
| Sony | KV32XBR96S | WHITE BAR ABOVE CHANNEL 70, RE-SOLDERED C225 | White bar on left side of screen only when tuner tuned abovechannel 70, uhf or cable. Found small amount of noise ~60mv on the 12 vline feeding tuner. Caused by C225 being cold soldered. Not decouplingthe line properly, slight amount of modulation w | ||
