Question about Sansui Audio Players & Recorders
You need a voltmeter for this and would have to check for DC on the speaker output terminals. Once you attempt to turn the unit on (before it quickly goes into shutdown), look for any DC voltage over
0.3V across any of the 5 outputs. If so, the digital amp IC is shorted and would require replacement.
Most common reason for failure of a digital amplifier IC is a speaker impedance change or wiring problem. You CANNOT connect any of the grounds together for any reason as the amplifers have floating grounds in respect to chassis ground and each other. The amp circuits often will tolerate this for a short while before eventually shorting out.
Your description of excess heat coming from the unit may also indicate a fan problem. Most brands have sensors built into the fan to confirm operation and can also cause shutdown if not running fast enough or at all...
