CD WON'T LOAD WITH MY PCE/IFU SETUP

turbokon · 04/14/2013, 08:07 PM

I was getting ready to play some Lords of Thunder this morning with my IFU/PCE setup, my preferred choice lately, and the disc just spins at the opening screen. So I decided to open up the cd-rom2 to see if the gears are ok as the gears are all original. No gears wear broken & they were moving freely. I then tested the cd-rom2 undocked with an audio CD and it loads and play fine. I then tested the ifu/pce with my tgcd and the same issues, cd just spins. At this point I thought the arcade card pro is failing but then I tested both cd-rom2 units and the arcade card pro on the tg16 & dock combo and both works fine. When I tried docking the PCE-LT in the IFU, the cd loads find. In conclusion, the cd-rom2 won't load with my pce but loads fine with my PCE-LT. Any body ever came across this before ? My PCE is region modded and plays both USA & Japanese Hucards just fine.

So I found out what is wrong with my pce, a couple of bad traces to the hucard slot. Now the hucard doesn't seem to want to align correctly with the contacts when inserted.

Sounds uncool

Was there some acid leak from one of the caps?

Anyhow, fix the traces and it might return to full life again

The bad traces was due to some scatches. I had to remove the wire ribbon to see it. The wire ribbon was brittle and were starting to come loose at the solder joints on the pcb. I replaced the ribbon with individual wires. I think the wires I'm using are to thin.

Why do you think they are too thin? How thin are they? Awg?

turbokon · 04/19/2013, 08:52 AM

32. Sometime the thickness matter.

Tatsujin · 04/19/2013, 09:31 AM

yeah it matters for a proper current flow and long(er) distances (voltage drop). but which both is very low in your application.

awg32 is 0.2mm, which should be more than enough.

So my issue might be something else. I tested it with four games and fantasy zone loads fine. Final soldier and image fight loads with scrambled graphics and street fight didn't load at all. All games load fine with my other systems. I tested continuity and everything checks out. I jumped from output of voltage regulator to pin 38 of hucard slot. System card load fine at the opening screen but I didn't test it any further beyond that in the ifu.

Image fight

Fantasy zone

And I killed my everdrive while testing it in the pce.

Yikes.

Sorry to hear that.

turbokon · 04/24/2013, 10:08 AM

No biggie, starting to think its a ram issue.

Tatsujin · 04/24/2013, 10:18 AM

might also be the fault of your magnavox TV set

turbokon · 04/24/2013, 03:13 PM

Lol, not bad for a TV I paid $26 for off Craigslist:)

The rams p/n are HSRM20256 LM12 & HSRM2264 LM10. Anybody know where I can find a suitable replacement?

turbokon · 04/24/2013, 08:51 PM

Just found a suitable replacement for HSRM20256, http://www.arcadecomponents.com/catalog/item/2251646/4758714.htm.

I'm still looking for the other one.

turbokon · 04/26/2013, 07:33 AM

I was able to find the hsrm2264 replacement. I'm hoping replacing the rams will solve my problem otherwise I'm taking my pce outside and stomp the shit out of it like I did my TG-16 back in 7th grade.

Keith Courage · 04/26/2013, 04:55 PM

yeah it kind of deserves it since it destroyed your everdrive.

Tatsujin · 04/26/2013, 10:35 PM

That farky piece of stinky rotten cow manure. Yeah give 'em what it deserves.

turbokon · 04/26/2013, 11:05 PM

Lmao:), it's all good. Kirkzz will repair my everdrive for free. I just need to send it in.
