Sega Cd Model 1 Stuck on Splash Screen

Hello I have a sega cd model 1 and its not working properly so maybe you guys can help me

When it boots up it goes to this screen and you can hear music .. but there is no way to eject the cd also no lights on the sega cd when you hit the reset button on the sega genesis it will just reboot to the same screen , I have cleaned all the contacts from the sega to the sega cd but that did not help so maybe one of you guys know something i dont :dejection:


Also I have one more problem sorry for keep asking so much

but I have a Chrono Tigger for SNES and could never get it to work so i opened it up while i was cleaning my other games and 2 of the contacts are corroded in half so there not making contact my dumb ass tried to solder it but not thinking there is nothing to solder to so its not sticking .. well anyway what i wanna know is .. will a Silver Conductivity pen will fix this problem because i really dont wanna throw my chrono tigger away i loved that game as a kid :love-struck:

Thanks alot

P.S sorry if the pictures are to big

I've got a CDX someone sent me to work on with the same issue. It would appear to be a capacitor issue but I haven't swapped the caps to confirm.

 

thanks ape i'll check in to finding those and give it a try , also do you know if that Silver Conductivity pen will fix those contacts on that snes game or is there a better way to do it ?

 

Yes, you need a silver conductive pen. They're not cheap, though!

 

How well do they perform? Might be the perfect starting point for a noob.

Thanks for all the help I ordered a conductivity pen they are high lol 17 bucks but oh well if it saves my chrono tigger its worth it I'll let you know if it fix's it or not thanks again

 

People used to use those pens to unlock old Athlon processors (you'd short jumpers on the CPU itself) and they'd work extremely well. Granted the distance was less than a centimeter but it should work for longer distances so long as the current isn't too high.

 

Call me crazy, but couldn't you just run a wire from the trace to the pins? I've noticed that SNES games only seem to have wear up to halfway the pins, so I'm assuming that the slot only makes contact halfway up the pins, meaning the wire shouldn't get squashed.

 

You can but that solder does add mass to the gold finger which can affect the slot it goes into over time in a negative way. A conductive pen is a great way to get around that - assuming it stays connected.

 

The BIOS do that when it cannot talk to the CD drive hardware. I suspect it can also happen if the traces related to the Word RAM (two long ZIP RAM chips near the leds) get cut.

Have a serious traces check on the main digital board. Probably a leaky capacitor or tow broke some traces down.

And while you are at it replace them all.

 

Possible for a dirty board? Saturn freezes on the BIOS screen when the board is dirty...

 

Saturn and MEGA/SEGA-CD are different animals ...

 

I'd look at the ribbon cable from the motherboard to the cd-rom drive board, I forgot to plug it in one time and this happened. It is also easy to plug in wrong. Usually the bios music doesn't play if that happens though but my experience is with the rarer JVC drive units, I have never had a Sony drive unit so that may be different.

 

That behavior depends heavily on the bios version. The only thing you can take for granted is that the rotating logo(s) does not show up until the system can finish the int for the drive registers. And if it hangs at that point, no logos are shown.

 

Hello. Sorry to revive such an old thread but was a solution found for this? Im having the exact same issue, bios screen, no music, and no "press start" its just frozen there. I had not used my sega CD in about 2 years and now I try to use it and I get this. Is this a capacitor issue? It has not been recapped, I guess I can always start there...
Thank you

 

That happens then the unit CPU cannot reach the CD drive electronics to init and check for a disc. It just freezes and stop the boot, failing to show the rotating logos.

Try dismantling it and disconnecting/reconnecting the flat cable between the main circuit board and the CD drive. Also make sure to inspect for leaky capacitors. They generate a faint chemical smell which resembles dead/rotten fish slightly.

 

I opened the system just as you did and inspected the ribbon cable and it seemed to be in good shape. The PCB however, leaves much to be desired...



What is that thing that seemed to have leaked? is this a capacitor? It seemed to have leaked quite a bit...

 

Lots of damaged traces can be seen on your picture. If you remove the capacitors, replace them with new, working ones and mend the broken traces it will work again.
