---|---|---|---|---|---|
Panasonic | NVHD100 | Narrow sync pulse output in E-E but ok when pre-recorded tape is played | Replace 3.3uF, 50v SM capacitor on hybrid IC301, If fault persists replace IC301 on the Y/C sub board | ||
Panasonic | NVHD100 | Dead after storm | Check the STRS6545 regulator chip and the mains fuse | ||
Panasonic | NV-HD100 | Display dead rest of functions ok | Change transistor Q1701 on Timer operation board | ||

Sony | STRD1015 | CENTER CHANNEL DISTORTION - ADDED GROUND WIRE | When using test tone in Dolby surround mode distortion isheard in the center channel as the rear channel test tone is active.Sound appears to be bleeding through rear channel to center channel.Center channel distortion is also noticable if rear channel v | ||
Sony | CFD10 | CD WILL WORK SOME TIMES - RESOLDER IC703 | Cd will work intermittently, IC703 has cold solder or nosolder. Unit will focus but not spin sending the optics on the outposition. | ||
Sony | CFD10 | CD WON'T WORK | Replaced melted cd lid, melted by high power lamp? and foundref 113 magnet holder shrunken also. Replaced ref 113 part number338697101 listed in manual and it won't fit properly, still too short. | ||
Sony | STRD1011 | NO SURROUND SOUND FUNCTION - REPLACED IC403 (5V REG) | Surround sound doesn't work at all. Checked clock on IC405 and there was no clock signal. | ||
Sony | STRD1090 | NO AUDIO OUTPUT - REPLACED IC404 | No audio output from any channel. Problem caused byDSP/IC404 on surround board. Although there was proper output from D/Aconverter and DSP had all necessary must haves but it held the dataoutput lines low. | ||
Sony | STRD1015 | HF BUZZ ON ALL OUTPUTS - ADD 820PF CAP BTWN IC631 OUT & GND | High frequency buzz on all outputs at no volume, more noticable when display dim(sleep timer on). Found 3MHz modulated with h/f buzz all around the set (including GND) especially at ouput of IC631. The Ic was getting worm |
