Sony | STRD1090 | SURROUND BOARD CHANGE | The surround board has been changed. In supplement - 2it gives us the circuitry change of the surround board but no part number.If you order part A4347-979-A it comes with IC 417. Not like the changein supplement - 2. I need the part number for the | ||
Sony | STRD1011 | NO REMOTE VOLUME OPERATION - IC231 INSTALLED BACKWARD | IC231 driver put in backward by factory. | ||
Sony | STRD1011 | MUTE BUTTON DOESN'T WORK - REPLACED DEFECTIVE Q255 | Front speaker output is very low, muting button lights up butdoesn't work. I found Q255 on A class board defective. | ||
Sony | HSTD105 | SPOT FROM OVERDISSIPATION NOTICEABLE ON MCB | Motor is possibly causing damage to the MCB. Consumption ofthis part is increasing gradually. It seems that the most cost effectiveway to solve this problem may be to install a smaller wattage resistorR-538? Please evaluate. Note: Missing parts on th | ||
Sony | FD10A | NO TUNING BAND SWITCHING, REPLACED SWITCH S-151 | Won't switch bands. | ||
Sony | HSTD107 | AUDIO CUTS OFF ON HIGH VOLUME - RESOLDERED C1222 | Unit has no audio on high volume (more than 25% of the volumeknob). A visual inspection of the main board shows C1222 has no solder onthe negative side of the capacitor. | ||
