| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | XRU220 | UNIT WILL NOT TURN ON (REPLACED LEAKY D202 AND D203) | Unit will accept the tape and play but once turned off can notturn it on. | ||
| Sony | XRC720 | NO AUDIO (FOUND AUDIO AMP IC781 DEFECTIVE) | No audio. Found audio amp IC781 defective. -HQ COMMENTS: Tokyo has analyzed samples we sent them and havedetermined that the defects are ususally caused by excessive reversevoltage being applied to the IC, probably by the power antenna relayturning off | ||
