A couple of possibilities: the bad electronics unit might have power supply problems, optical sensor problems, or other problems with the electronics. If you have some tech savvy and a voltmeter, you could check the power supply voltages. This circuit is likely in the close vicinity of the fuse. On the output side you should see a +5 volt, +12 to 15 volt, and perhaps a -35 volt (approx). The +5 supplies the logic circuit, +12 the motors. If these voltages are missing, or way out of tolerance, you will have a dead unit. A frequent cause of problems in the supply is bad electrolytic capacitors, especially in the older units (Panasonic manufactured rigs, late '80s/early '90s). Possible values on these capacitors: 2200MFD/10V 1000MFD/16V and several others. Replacements can be supplied by MCM electronics, Mouser electronics. I use the Panansonic FC series from Digi-Key Electronics. Sensor problems: Many VCRs have the sensor opticals mounted on the main circuit board, and locate themselves in particular spots in the mechanical section. One or more sensors detect tape loaded, one each for the supply & takeup spindles. If any of these sensors (especially the supply/takeup sensors) are non-working, the logic circuit will detect an error condition, and shut down the unit or at least put it into a stop mode.

I told you in premium post that Unplug your Combo for 5 - 10 minutes from AC outlet and replug it. Now push eject button and take out cassette.

I make no claim to being any kind of an expert techie but it sounds to me like there are one or more loose or badly worn parts inside your machine. If you haven't had a look at the innards, try that. Loose things can usually be re-secured and, sometimes, worn parts can be replaced.
