Question about Samsung SV5000W VHS VCR
Hi I have a problem getting power to the unit. Fuse looks good. Who can repair or replace the power unit? do know any service center near Washington DC? Please advise
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. If this is a high dollar > $250 VCR, it might be worth service center repairs. If not, then it is a disposable (unfortunate, but the way it is with most modern electronics).
