SharpDV5932FAILURE OF C619MOVE R632 FROM THE CLOSE AREA OF C619 AND REPLACE CAPACITOR14-09-04
SharpDV5932Procedure for setting NVM for no soundPut set into service mode by momentarily shorting pins 2&6 on service plug as per manual. Scroll down to NVM pos with ch +/- adjust first to digits to correspond with location value on technical bulletin if the value number doesn't correspond go to NVM val and set last two digits to correspond with vol up & down; then store with standby button. Repeat this with all 19 settings then short pins 2 & 6 to come out of service mode. Switch set off and on from mains switch to reset.14-09-04

SharpDW100 66FW53HDead - usually IC705 opto is to blame - Pt. No. RH-FX0106BMZZchanged to RH-FX0110BMZZ - When the opto fails it usually takes out the line output transistor(BUH515) and the feed resistor to the line o/p stage 1R2W resistor. You need to add a 145v avalanches diode to the circuit on the print side directly beneath C720(H.T. reservoir cap) which also will need to be replaced.14-09-04
