Re-Capping a Pioneer CLD-V870 Laserdisc Player Power Supply

Image
Recently, I received a dead Pioneer CLD-V870 Karaoke style Laserdisc player.  When plugged in, there was no standby light. I performed the usual step of removing D105 surge suppressor from the power board since this commonly failed on some later models.  I clipped both ends and removed it, then replaced the fuse with a known working one.    Still, the standby light nor the unit would come on. Next, I had to manually wind the gears to get the tray to eject.  Once the tray was out, the power supply could be safely unscrewed and removed.  I inspected the board and found a number of capacitors.  Rather than troubleshoot one by one, I took an inventory and ordered replacement caps from Digi-Key.  I saved the list of capacitors for VWR1269.  Link here Before de-soldering any of the old caps, it is a good idea to mark the tops of each cap with the same directional line.  In my case, I drew a line pointing towards the front of the unit....

 Modifying a Pioneer SP-99D AC-3 processor with TOSLINK digital out

Image
During the later years of Laserdisc in 1995, Pioneer started releasing Laserdiscs with AC-3 sound capability.  This meant you could get 5.1 surround sound on newer movies, as long as your player supported it and you could feed the audio signal into a demodulator or processor. The big difference between processors and demodulators are the capabilities and how they output their signal to a receiver.  Demodulators normally have an input for AC-3 via a coax connection and sometimes will have an input for TOSLINK(SPDIF) optical.  From there, the demodulator processes the signals and outputs them via a single cable to a receiver whether that be coax or optical.   Example of a demodulator - Pioneer RFD-1 Processors, however, would normally output their sound via 6 discrete cables.  On receivers, these are sometimes referred to as Multi Channel In.  The 6 channels are Front Left, Center, Front Right, Subwoofer, Surround Left and Surround Right.  This is all we...
Introducing a new blog - Laserdisc Service.  This blog will range in multiple topics covering the service, modification and general fixing of Laserdisc Players. I began to get interested in Laserdisc back in 2017.  There are so many odd and interesting things about the format that have kept me interested over the last 5+ years.  One thing I immediately noticed is the high quality players are expensive to purchase when they are perfectly working, so the best way to score a deal is to get a player with an issue that has a documented fix. This blog will cover some of my past fixes and modifications, but also cover new topics.  As I get players in, I will post about the arrival, what is wrong with them, a diagnosis and ultimately (I hope!) a fix. My success rate in repairing over 50 players is 90%.  Of the players I cannot fix, I will save whatever parts to be used later since some are interchangeable.  I mainly work with Pioneer, but have worked on a couple of...
