So far this worked for my Sony MDP-333. I pretty much was dead in the water for CAV discs and CLV discs had a hard time starting up. But this resolved all of it. Only other issue is scanning on a CAV disc causes it to trip out and stop playing. I may have to adjust more than the focus at that point, the tilt perhaps? I have not tried.

Great to see another player being modded for more functionality. This board has got the footprint for the SPDIF Jack next to the CD syncro socket at the back. There is a surface mounted resistor missing just near the chip that you soldered the wire to that stops the signal being router any further through the board. You can then cut the panel and it looks pretty much factory fitment. No extra wires etc. couple of components to fill the OEM spots but aren’t strictly required and the mod looks factory. Obviously yours works which is great but maybe the next one you need to mod you could check the back edge of the board for the empty footprint. There is a thread on LDDB by much smarter people than me about the exact components to fit which I have used as a guide in the past to mod players like this.
@Laserdiscrepair22 күн бұрын
You are absolutely correct. I put that in a CLD-V2800 and it looked factory. The hard part for me was getting the square hole just right, no negotiating on that one. Maybe I'll make another video showing that install. Thanks for watching!

This is one of the players I own but it's considered one of the weaker of the players I own. What I do like about this player is it's a lot lighter than other models. I believe this players only weighs around 16 or 17 pounds which is very light for a laserdisc player. 20-30 pounds might not sound like a lot more for the other players but it is because the weight isn't proportional and it's odd weight. Now since I've moved players often I'm a bit used to moving them but for people just getting into laserdisc and want a couple players to own. I can see that be annoying the heavier the weight is. I'm a fairly strong guy too since I've done Construction Work through out my life working for my Father. I did the grunt work so lifting heavy stuff or moving liquid cement in Wheel barrels. I wonder if the older I get if it's going become more of a pain moving laserdisc players from place to place. I don't think so because I believe the last thing to go is power. There' a lot of strong guys in their 60s and 70s.

Hi, this is great. Do you accept machines from viewers for repair? Thanks!
How did it perform when hooked up with speakers? My old MDP-455 mod from years ago was a problem due to the lack of a “mute” connection on the AC3 board and I would occasionally get a loud bang of sound on my speakers prior to disc start up. After that, the disc would play fine until the next side break and I have the loud bang again depending on the disc played. I’m not sure if it’s just a Sony thing which is why I ask. I ask others who have modified Pioneer units without “mute” added and they seem fine. Nevertheless, all the mods I have done since incorporates the mute circuit and I have never had the “rude awakening” since then 🙂.

Why risk potentially damaging or breaking the laserdisc player connections? I wish I could see a benefit? This is an example of having far too much free time! Adapters are inexpensive and pose zero risk as they are to the laserdisc player. There are also plenty of upscaling options if you are looking to make the video quality more appealing on modern TVs. Such as the RetroTink4k. Regardless, If the time and effort was worth it to you, I guess that is the overall benefit! Thanks for sharing your mod!

If you're going coax, there are some considerations to be made. I think you may need a resistor and possibly a small capacitor before you connect to the RCA jack. Also, you don't need the +5V for RCA connection. The +5V here is to power the light.

Mod only works on the AC-3RF input. I'm trying to chase down someone from LDDB who made a auto switching circuit. Essentially, they are watching to see if AC3 is active or not active. If not active, it sends the optical in through the optical out.

@MovieGuy8462 жыл бұрын
Most likely not. Might be a CD centering issue but hard to say. It does come up with the error code of E5 which is a slider issue. Odd... but I noticed a hum when the CD was loaded and that sounds like motor trying to spin (maybe the spindle or maybe the pick-up motor). There could be an issue of dried grease on the laser pick-up track since it has to be come in closer to the spindle motor (e.g.: if the player was used mostly for LD, that would explain grease getting dried up on the inner most track preventing smooth movement for the pick-up).

@@SurgemanX The more I watch this video, the less likely I think it is a centering or bad laser issue. The fact that the CD never gets a spin up (which is needed for the player to identify the disc) tells me there is something jamming up possibly on the clamper side or the spindle motor platform. There is a spring loaded piece on the spindle platform called a PRC Hub that supposed to go down when a CD is loaded (it will stay up with an LD since the larger hole of an LD just passes around it). I would check this out by simply using your fingers to see if it goes down smoothly. If not, it may just need some oil to loosen it up (or need a cleaning).

@@SurgemanX That’s a lot of money to spend on essentially a guess that you are making. A good repair technician knows that giving that kind of advice without actually seeing the device in person is bad troubleshooting. Also, it doesn’t hurt to investigate all the potential avenues first that could cause this issue before spending a fortune on a part that may not be an issue. And honestly speaking, there is something obviously wrong if the spindle doesn’t turn the CD (you don’t hear that hum?). Lastly, I’ve owned players since 1988 and not one of my now 15 working players have ever had an issue playing a CD or LD (laser pick-ups on LD players don’t go bad that often). It’s actually more common to see a failed spindle motor before a laser pick-up. And today with people shipping players for purchase, now you can throw in mechanical alignment as one of the more common issues now for player issues.
