Life has got me busy atm and so any further repair to the LD repair is on ice..however on my travels I snagged another box of LD's ..this time 50 for $70 AUD ...another rather older set but many top rated movies. Here is one old gem ..just the title alone does it for me!

As soon as Ive installed all these new blinds in the house in time for our summer I will be back at the my can of Plastidip ready to go...and now plenty of discs waiting to enjoy.

For Reference - Whilst searching for more info with this unit found out How to get into the DDP-1 Test Mode - for those that might need to one day

To put the Yamaha DDP-1 in TEST MODE:

1. Plug unit into AC power and make sure unit is OFF.

2. Push both the MODE and MENU button simultaneously.

3. Push the POWER button ON.

The screen will show:


Then the screen will change after a second or two to:


Now the MODE button can be used to change what is after the colon to:


The MENU button is used to bring up the settings for surround sound speakers, low frequency enhanced speaker, Pro-Logic input, AC-3 input, and test tone.

The PARAMETER button brings up a slew of other diagnostic and sound settings...

Yes think it could be the fault as clock running and Display does not go past its power start-up state.

Ordered a CSTLS10M0G53 3 pin 10mhz crystal from the UK...given the slow delivery at the moment...wont get it until mid August if lucky! will have to be patient! Certainly nothing to lose in trying to swap it out.

Picked this up for very cheap - no manuals no info - much be rare - all in one Karaoke machine with Cassette, Laserdisc, CD - Circa 1992? Sanyo..

For the Record its a Sanyo LV-K77 Model
Im betting nobody has seen or heard of or knows of this machine ?!

Does the Laserdisc work..sadly no....disc loads and is recognised - Hear ticking squealing as if the laser is trying to focus/search but PLAY onscreen turns into STOP and it spits the Laserdisc back out...

Has a 'JET TURN' both sides function.

Found a Owners but no Service Manual.

Only Sanyo player I could find some other info on is a LV-P500 ..

This unit is is literally a normal stand alone player put into unit..with a custom front plate and connectors.

Sound is good bass is very good..using with bluetooth input...cassette works well actually lol

my thoughts..its ugly...sounds good...but pity the Laserdisc is not working.!

:D :D :thumbup:

Thanks to all who helped ! now working as it should. New Optical Assembly fitted.

The replacement part was not identical - wires/plugs differing length..guides missing.
Casting was exactly the same so managed with some micro surgery to make it fit.

Issue all along - Optics Lens slightly cloudy...a lot of humidity here...but also its a Karaoke Unit therefore may have had a smoke filled retro life back in the 90s.

Thanks Cplusplus very helpful.


OK It Works...but more testing tbd!

..was not familiar with the 'Karaoke Mode' button :lol:

This mode seems to 'Pause' each Track...was that it all it was...More testing to be done with more CD's....just played a CD complete all good..sounds good.! Closer at the least!

So how did you fix the CD playback issue? Pot adjustment?

Thanks ldfan ! learnt more from your post.

Thats the thing - I believe I must have pressed' Karaoke Mode' somehow! and without the TV on couldnt see that the track was in 'PAUSE'. There is no indicator on the unit!

I have just tried a bunch of CD's and all good! adjustment to POT's or Mechanics Needed :thumbup:

The unit sound output is very good.

This unit is kinda like a 90s Music and Video Jukebox ..and now with Bluetooth.
Its a keeper!

We have a result !

Replaced Resistor and Cap - used a solid jumper wire to bypass corroded trace.

Hopefully will keep working!

Player fully working ! -
Slightly less noise wrt to the picture compared to what my D770 can do - however not quite as detailed.

I can confirm replacement of just the one capacitor the C12 2.2uF 50V Electrolytic has fixed the PSU for my D780 !

Standby light now on and unit lights up and powers on as it should.

However I do have another issue ..seeing error U1 on the display?!... when powering on the tray will go in - you hear whirring and then it spits the tray back out..repeating the process if you let it.

Im hoping this is a VEB1184 belt replacement fix !? -

Just fixed my Pioneer CLD-D780/604 - replaced the original broken grey Mholder with the replacement Mholder I purchased from user Oppelix

Worked a treat !

First time Ive changed an was a lot easier than I feared - the easiest repair yet!..the replacement Mholder fitted perfectly...fixing holes lined up - cogs lined up...perfect.

First time tonight I've been able to watch discs with the D780 using Side B ....awesome ! (another junk player fixed)

Tried to take some photos of the new installed Mholder tonight..but lighting isnt great ...will post a couple of photos when in daylight.

Cheers to Oppelix for allowing me to make this player play properly again!

Another Yamaha DDP-1 Digital Output Modification success!

Tested working nicely! - no more Lipsync issues when using DVD Recorder for Video enhancement.

That leaves the Marantz DP-870 to mod.

Marantz DP870 Digital Out Mod Success!
Works fine!

A lot tighter to fit in - Height of the Module is a challenge.
