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

-


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.  This way, I can look at this in case I forget later which way the cap was positioned on the board.

 

Most of the capacitors are easy to remove, simply de-solder one side at a time on the underside of the board.  The larger capacitors normally have some kind of glue to help anchor them down.  I removed the glue with a small pair of pliers to free the capacitor.


When all of the capacitors are removed, ensure you have clean through holes so you can install the new capacitors.  Solder wick can help remove excess solder in the holes.


Optional step, but you can test the old capacitors if you were unsure of which ones may have been failing.  This one tested fine.


Here is a comparison of one of the larger capacitors - old on left and new on right


Finally, here is an overhead shot of the power supply with new capacitors.  There isn't much of a difference except maybe for some capacitors that are differently sized.


Once the power supply was installed back in the player, the standby light came on the player came to life!

This power supply, the VWR1269-A was popular in a few late model players, namely CLD-V870, CLD-V880, CLD-D505, CLD-D605 and CLD-D606

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

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...
