Question about Panasonic PV-D4734 DVD Player / VCR Combo
No power at all from the unit? there is likely to be a fault in the switchmode power supply, which can be caused by any number of components, including leaky electrolytic capacitors. With any SMPS service, all the caps must be replaced together to ensure reliability, along with any IC regulators and diodes which may have been damaged by the faulty caps. If the PSU also features a chopper transformer, this may have an open-circuit winding. Either way, this would require workshop attention by a qualified technician with adequate equipment, and access to replacement parts.
Best option is to submit the unit to an authorised service centre, obtain a quote on the likely cost(s) involved, get a second opinion; then you can make a firm decision on whether it is economical to pursue the repair or not. Up to you.
A dead machine is not always just a simple blown fuse. The cost of the repair will depend on the extent of the original failure in the power supply and whether it has affected anything else in the unit.
