This as a cabinet I bought with everything but the LD player and disc.

Since then I bought a Sony LDP-2000 which works great, a lasercon multi-rom board, and a hi-tech board to use the sony player.

I hooked everything up and when I put in the DL disc, it only goes to a paused black screen. When I put a Space Ace disc in, it only goes to a ram testing screen and stays paused.

When I fire up the game the Hi-tech board goes through all 4 LED's several times, then blinks on the first one and no lights stay on.

I think I have everything hooked up correctly.. but there are two loose wires that are cut that go up to the top of the game (see video), but these don't appear to be anything critical (go to :40 in to see what I'm talking about.

Here's a video, I'm hoping to get some help and get this thing running :)

Do I need to set the dip switches a certain way on the DL main board?

Go up to 720P for better quality

The cut wires in the video looks like they are/were the power feed to the laser disc player.

Dip switches, yes you will need to set them correctly. On the main board, did you get a sheet with your MultiRom card? It explains how to set these switches up. You will also need to setup the dip switch on the Hi-Tech card to tell it which laser disc player the main board was set up for. See here: http://www.dragons-lair-project.com/tech/docs/hitech/hi-tech.htm

Does the laser disc player play the disc fine without it hooked up to the game?
Is your baud rate setting correct on the player?
Do you get a single beep right after you turn it on?
What does the score display show after this beep?

Make sure the ribbon cable going to the display that pin 1 matches up (I found that this can cause problems if hooked up backwards).

I am not an expert, but I did learn an bunch of things while rebuilding my unit just recently.

The paperwork with the muilti-rom talked about setting it up through watching the display run through numbers and selecting a rom that way.. or so that's how I read it.

There is no dip switches on the Hi-tech board, only jumpers, and it talks about which LD player you would have originally been using , which is the original DL player.. which is what it is set to with no jumpers installed.

Does anyone have a link to info on what my pins should be set at on the DL main board? I can't find it anywhere when referencing the Hi-tech board.

And just to clarify, I am totally new to this, so if what I posted above is wrong please let me know... I'm learning as I go :)

Which board do you have REV A or REV C (looks like a C in the video but not 100% sure)? This will tell you which original player, LD-V1000 or the PR-7820?

Score display, what does it have? See here: http://www.dragons-lair-project.com/tech/docs/initialization.asp
edit >> actually now that I think about it, I think you have to do a ROM selection first before it does the intialization. I don't currently have my MultiRom board to verify that.

MultiRom - should have came with many sheets with all the DIP settings for all versions of the games plus a grid sheet for you to fill out for the DIP settings you will be using. See here for all the info: http://wood1st.com/LaserCon/MultiROM/index.htm

I've made some progress, but still can't get things to work. Here's an update on what's going on:





 
You have a rev C main board, look at the board right next to the bottom of the 2 dipswitches.

There is no jumper wire there, meaning the board is set for a LDV1000 laserdisc player originally.

You are using a lasercon rom board, you need to take the page for DL version 2 switch settings from the lasercon website, set your main board to those settings using the LDV 1000 setting making switch B3 ON.

Your hitech board came with 3 jumpers.. install one on J9, next to the ribbon cable connection on the hitech board.. This sets the hitech to use the LDV 1000 protocol.

Thanks for the help Brian.

I still can't get this thing to run, the jumper comes pre-installed on the J9 so that's there.

I have the B3 switch set to on, and I've tried turing it off to no avail.

Any more ideas from looking at the videos?
 
From what I can tell it looks like there is a communication issue between the laser disc card and the main board, that is as far as my thinking is taking me at the moment. I would check the cable and make it is good and then maybe the socket on the main board.
