No, NOT a trick, a Halloween treat! Presenting the Dead of the Brain 1 English patch by David Shadoff for the DEAD last official PC Engine CD game published by NEC before exiting the console biz in 1999! I helped edit/betatest and it's also a game I actually finished in 2023, yaaay! Shubibiman also did a French localization. |

Console Repair/Mod Center / HELP - PC Engine Duo repair
12/01/2016, 10:39 PM
Hi,
I received a PC Engine Duo for a repair and mod.
According to the owner the console doesn't play cards or CD and a capkit might be needed.
When I tested it the first time, cards played fine but in CD mode it was stuck on a static, plain white screen (like when a normal PCE is switched on with no card).
With the help of a logic probe I found a floating address line on the BIOS ROM. I patched it with a piece of kynar wire and the CD mode was restored:
It as time to test it with a CD: nothing, the CD doesn't even spin, sign that the lens doesn't 'see' anything. So I installed the capkit (quite a lot of caps) and... No change.
The owner ordered a new lens and once fitted the console now recognises disc, sometimes I can see an error screen with a game and I can enter the audio mode with a normal audio CD but nothing more (no tracks data, length, etc.):
The owner pointed me to 2 different threads explaining how to adjust the pots. I carefully took measurement of each one before starting the job and followed the instructions carefully.
But still, CDs aren't read properly.
Does anyone have an idea at what to look?
I'm not really specialised in PCE, I've just bought one few weeks ago, 18 years after having sold my duo!
Thanks for your help.

Hi,
I'm new here but I'm known on many other international forums under the same name: Apocalypse.
I've been a video game collector for 20 years and arcade boards collector for 10 years now.
I've got an electronic background (got a degree in electronic and have worked a couple of years in an electronic workshop doing repairs and test benches).
I also have a computer programming background which is most useful to repair/hack games.
I've recently created a blog where you can see my repairs (mostly arcade games but also consoles from time to time):

I came here to get some tech info so see you in the appropriate section.
