Question about JVC HR-J692U S-VHS VCR
This likely indicates a dead power supply, or a blown fuse in the power supply, and if the fuse is blown, this usually indicates a serious problem with it. If you have a voltmeter and some tech savvy, you could check for proper voltages produced by the power supply circuit. A normal power supply will produce: +5 volts, +12 to 14 volts, & a -40 volts or so. The latter is to power the LCD display, if present. If these voltages are missing, or way off, then you have a defective component in the power supply circuitry. Incorrect voltage values are usually point to a defective electrolytic capacitor. Replacement caps. can be found at Digi-key Corp.-- their Panasonic FC series is what you will want. Or, Mouser Electronics has suitable. If there is no voltage at all, then you may have a blown switching transistor, and perhaps a few other small parts bad. Tech savvy is a requirement here, as these kind of failures are frequently caused by a problem elsewhere, and a repeat poof is almost certain unless the other problem is found & repaired. Otherwise, if this is a low dollar VCR like most of the last 10+ years, repairs might not be economical.
