[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Final update:

All of the PCE Works discs that gave me problems work now.

Felt good to get in some awesome old school gaming. Thanks again to this community, and a huge, huge thanks to PCE Nuggets. I really appreciate everything he did for me. Cannot thank him enough.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

I wanted to provide a quick update on this thread.

First of all, thank you immensely, to everyone who provided guidance and offered their help. You all have proved that this is a top notch community and I really appreciate your assistance.

On to the topic. PCE Nuggets contacted me as he saw this thread on the forum and I began a dialogue with him about the issue, on how I had I troubleshot everything so far and if he had any suggestions etc on what I could do on my end to fix this, as I like to gain in knowledge and try to be self reliant.

PCE Nuggets offered to work on the system and resolve the issue for me, at no cost to me whatsoever, as he stands by his work. I shipped my Turbo Duo off to him and paid for the shipping myself, which I voluntarily did to place a high amount of insurance on it and signature required, as I am paranoid beyond measure about how the USPS handles my packages. Seriously...I've had packages arrive from the USPS that were marked FRAGILE in HUGE Letters everywhere on the package, and they still had massive, gaping craters the size of the box itself on the sides where it had been punctured. I don't take chances on anything I ship out to get repaired because of incidents like that.

And resolve it he did. I sent him my PCE Works discs that had failed along with my Turbo Duo and after some calibration and extensive testing on his end to ensure the problem was fixed, he sent the unit back to me.

Two of the PCE Works discs that gave me nothing but absolute fits when I tried to play them in the past, both booted up instantly without issue. Previously, the system wouldn't even get to a set disc error or anything. It would just endlessly spin. I'm going to play Spriggan and the other games I had issues with tomorrow after I get some sleep, but I am confident that the problem is resolved 100%.


I also sent in a PC Engine Shuttle as well, to be RGB modded while he was working on the Turbo Duo. That one I paid for.

Let's just say that I am beyond extremely happy with the end result of my PC Engine Shuttle's RGB Mod. The RGB Output from my OSSC into my HDTV is so sharp that it makes my eyes bleed. I loaded up Jackie Chan's action Kung Fu and all I saw was pure, unadulterated, crisp RGB BLISS.


So again, thank you everyone for your help. And to PCE Nuggets, dude, you rock. Again, I cannot thank you enough for helping me out as extensively as you have. It is so very awesome to know that reliable modders like you are out there who care extensively and deeply about the work they do.

Night all for now. Take care.

I'm using the NEC AC Adaptor that came with my Turbo Duo. When I bought it years ago, it was Complete In Box, so it had everything that came with it.

Yeah MNKyDeth. Everything works fine that is a regular music CD or Turbo Grafx CD or Turbo Duo CD, as do most of the PCE Works discs.

It's just these few discs that won't read. It's frustrating. I am unable to test burned CDs at the moment, but I guess I can try that later. See if that works. I believe most people recommend 1x or 2x burn or the slowest speed burns on cd-rs right? I don't like using them, but, I can try to see if I can get one burned to test.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Well,

That was a massive exercise in frustration. I took it apart and adjusted the pot on the CD Rom Lens time and time again, each time, doing what seemed to be hair thin turns of the pot for the lens.

The most luck I got was the splash screen of spriggan loading once, then the system crashing into a load error, and two splash screens from Sapphire saying it needed the Arcade Duo card...

Despite their being an Arcade Duo card right in the system.

I'm admittedly frustrated. Aside from trying these in another system which I do not have, or taking these specific discs to a professional resurfacing service for the discs and see if they load after that...I'm not sure what else I can do. I hold no ill will towards PCE Works, I just got the bad luck of the draw on these. I mean, they sent me replacement discs for crying out loud. I wish I had multiple systems to test these on but I don't.

Only other thing I can think of is try any other suggestions you guys have, or ask PCE Nuggets to check out my system as he was the gentleman who did a phenomenal job modding it and send him the discs and the system though I fear his results may be the same as my own. Not sure.

It's just frustrating, because the other PCE Works discs load fine. My other games load fine, freaking magical dinosaur tour loads fine.


I'm genuinely open to any suggestions you guys may have. I'd like to get these working.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Thanks. I appreciate all the help.

I assume a screwdriver of appropriate size would work to adjust the pot yes? Should I remove the two connections of wires into the lens or can I adjust the pot without doing this?

Also, is there a way that I can test the system and adjust the pot while it is still open, safely, to see that it is reading disc after each adjustment? Thoughts on how I can do this? Or is it recommended to seal it up after adjusting and rinse and repeat the take apart process?


I'll try and open it up tonight, see if I can get this working.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Thanks. Do you have any pics or anything to show me the specific part? I'm admittedly a complete noob to dealing with Turbo Duo and modding etc.

I know the basics of PCBs, traces, resistors, caps, etc. But I am by no means an electrician. So any pointers would be helpful.

I do appreciate your correspondence with me Keith. Thanks Man.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Unfortunately, No dice.

I moved the console to the floor, far away from the TV and other sources of EMI. I ran my RGB Scart cable to my OSSC from there, and had the power supply plugged into it's own outlet with everything else unplugged.

The Drive still won't read those discs. The behavior of the system is odd. It's like it's trying, and trying, and trying. It never gets to a set disc error, even when left alone for over half an hour.

It just keeps trying. The Symptoms are that it will spin up, the activity light is red, and then I hear something that sounds like a " Skip ", or a click, like the cd is skipping or something? The red activity light also blinks every time the skip happens as well.

Almost like the drive is resetting itself or something. I just...I'm not sure what the deal is.

I'd love any feedback you have or anyone else has. For now, I've put the system back where it was.

[Console Repair/Mod Center / Re: Problem with a few discs being read on my Turbo Duo]

Sorry for the late reply. Been busy with Physical Therapy today.

Aye, I ran a Music CD through it and it loads up instantly. The Lens has no issue switching between the tracks etc.

I should note, that the Turbo Duo is very near the TV and the AC Adapter has a lot of power cords in alongside it. Not sure if that means anything for EMI or if the disc reading should still be a non issue, but, felt it was worth mentioning just in case.

[Console Repair/Mod Center / Problem with a few discs being read on my Turbo Duo]

Hey all,

Hoping someone can help me out here and provide to me some answers. Or at the very least, suggestions.

A while back I got my Turbo Duo recapped and RGB modded, and I also had the lens replaced as well just as a precaution. Which I am now kind of kicking myself for, but maybe I shouldn't be.

See, I have several reproduction discs from PCE Works that aren't working in my Turbo Duo, for some unknown reason. Now, I've bought tons of stuff from PCE Works in the past and have had zero issue with them. Before and after the recap work etc.

But now, these 3 discs, and even the replacement discs that were sent to me, refuse to work. I don't even get a please set disc error on my Turbo Duo. I just get endless disc spinning and a blank, black screen. Again, it's just these games like Space Fantasy Zone for example, and Seirei Senshi Spriggan and Sapphire that won't work. And yes I have the hucard to load Sapphire.

I saw a youtube video where a suggestion was that EMI was causing the issue for one person, not sure if that is true in my case as testing that would be difficult right now since I had surgery on my left shoulder and even typing this out is...painful, to say the least of matters.

I've been in touch with PCE works and they've been helpful, giving me replacement discs for the 1st ones that don't work while investigating the matter on their end.

They suggested one thing it might be possibly is the caps responsible for the drive. I've also seen weird things on youtube where a CD R wouldn't load until the lens plastic cover was removed.

Since my system was recapped, is this something as potentially easy as adjusting the pots? Anyone have any suggestions? I'm honestly open to all thoughts, etc. Generally speaking I don't like using CD-R's at all and try to stick to official media or just repros like PCE Works since some official releases now go for an eye, kidney, and liver alongside your first born on Ebay etc.

Any and all thoughts and suggestions are appreciated. I'm curious if this may indeed be a cap issue or if it is related to something silly and easily fixed. I'd really love to be able to play these games.

[Console Repair/Mod Center / Re: Turbo Duo will not power on]

This may sound silly but 85% of the time when someone contacts me saying their system will not power on it turns out to be a bad AV cable.

To find out if your system is indeed getting power simply press the run button on your controller with no game inserted to see if the CD loading light turns on.

There is no power LED on a Turbo duo. Only a CD loading light.

Thanks Keith, I appreciate the assist.

Turns out your words triggered an idea in me that it may not be the AV cable at all, but actually the Audio Video ports on the back of the Sony Trinitron I have. I moved the system over to the HD TV and hooked it up and boom, got a video signal.

I feel a bit silly, but also relieved it's such a simple problem. So, I appreciate the advice. You definitely helped me figure out what was going on.

Thank you once again. I really appreciate it.

[Console Repair/Mod Center / Turbo Duo will not power on]

1st post. Shame that it has be one like this even though I've been a member of the forums for a bit.

Recently I got a copy of Rockman for my Turbo Duo and went to play it, only to find to my dismay that my Turbo Duo will not power on at all. I don't have a Security bit, so I haven't been able to open the unit yet to see if any caps are leaking or something has occurred to the board. All I know is that last I tested this system, it was working fine on my new 30 inch HDTV in a test of the composite signal through component inputs, and that Rondo of Blood played fine. I disconnected the system. There was no sign of any issues during gameplay, nothing at all.

Fast forward to 2 nights ago. The Turbo Duo won't power on, at all. I reconnected it back up and was looking forward to playing Rockman when boom, no power, no nothing. Tried multiple outlets. 

Took the Multi-meter I have and the Power supply is registering 14 v DC, so I don't think the power supply is a problem either as my genesis bricks register the same voltage.

At this point, I'm thinking it's either the fuse, or possibly the power adapter in the back of the unit...or...worse case scenario, bad caps.

I'm waiting on a security bit I ordered to crack open the console and take a look as I do not have one on hand currently. That all having been said, if I find that bad caps have caused this, does anyone on this board know of a solid, 100000000000% reliable repair service that can service this unit and get it back up and running?

My Turbo Duo's shell is in near pristine condition, and admittedly as easy as the plastic scratches, I'm extremely nervous about sending it out to anyone for repair, due to so many shady repair and modding services being out there. Last thing I want is to get back a Turbo Duo that looks like it's went through Armageddon. Or even worse, a different one than I had sent in for repair.

I know I eventually need to get the caps replaced on this thing anyways. So, any and all feedback would be immensely appreciated. I'm hoping this is just a blown fuse for some inane reason, and that I can swap out the fuse to find out.

Preferably, anyone who has a storefront and an online presence with a good, solid and reliable reputation with their customer base would be preferred for this.

I'm also open to feedback on what I can do to look into for repairs on this myself. Admittedly though, I have zero soldering experience and am most assuredly not an electrical engineer.

Thanks in advance.
