ricky Posted January 6, 2021 Share Posted January 6, 2021 (edited) Hi friends, I have a major problem with my SGM third Edition, I no longer have sound with SGM games which use the three additional channels. when I use the Super Game Module Test utility, I have no sound on C4, E4, G4, just a little crackle. I tested with SGM compatible games like "Booming Boy", "Goonies" or "Knightmare". The malfunction occurs on three Colecovision PAL and SECAM consoles. So what remains to be done ? it was working fine three weeks ago and then suddenly nothing. Thank you for your help, I am confused with this dysfunction.

+5-11under Posted January 6, 2021 Share Posted January 6, 2021 I had the same problem. I ordered one myself, only because it was faster than contacting and getting a replacement or repair from Opcode. Quote Link to comment Share on other sites More sharing options...
ricky Posted January 6, 2021 Author Share Posted January 6, 2021 This is not normal, is it the chip AY-3-8910 that has burnt out ? I just pre-ordered a sixth edition SGM, but I'm not going to drop my third edition SGM, which I like because it has the "Colecovision" label. Never mind if it costs me money with the shipping costs to have it repaired, I care about it like the apple of my eye. Quote Link to comment Share on other sites More sharing options...

I just ripped that label off, opened it up, replaced the chip, closed it again, and put the label back on (with 95% of it sticking properly ).

ricky Posted January 6, 2021 Author Share Posted January 6, 2021 So the screws are behind the label, I'll see that... thank you for your answer, Quote Link to comment Share on other sites More sharing options...
+5-11under Posted January 6, 2021 Share Posted January 6, 2021 I think so. It was a few years ago. Best contact Opcode either way, to provide best support, such as a full repair, or replacement label if that's the way the two of you decide to go.

ricky Posted January 6, 2021 Author Share Posted January 6, 2021 Already if Opcode takes the trouble to answer on this topic, we would then consider the best procedure to follow ? Quote Link to comment Share on other sites More sharing options...
ricky Posted January 7, 2021 Author Share Posted January 7, 2021 (edited) So it reassures me if it is possible to change the AY chip myself. Which one do I need, the AY-3-8910, or the AY-3-8910A ? A brand of preference ? Edited January 7, 2021 by ricky Quote Link to comment Share on other sites More sharing options...
opcode Posted January 7, 2021 Share Posted January 7, 2021 Please contact support at opcodegames dot com. We will replace the board. Quote Link to comment Share on other sites More sharing options...
SiLic0ne t0aD Posted January 8, 2021 Share Posted January 8, 2021 I'd have Opcode fix it for you, or else you'll void your warranty. You also have to be careful about buying vintage IC's in general anymore, especially on eBay. Buy from a reputable vendor if possible, like arcadeshop.com for example. There's so many Chinese knock-offs/clones nowadays and they're getting more & more clever when it comes to counterfeiting. Stick with GI or Yamaha branded AY chips. Check out this video and you'll see what I mean. https://youtu.be/k72SFBOZ_lw Quote Link to comment Share on other sites More sharing options...
ricky Posted January 8, 2021 Author Share Posted January 8, 2021 It's amazing how well counterfeit Chinese products are, I hope that one day there will never be any counterfeit SGMs on sale, like Dreamcast GDMUs can be found. I have the impression that it is more difficult to find an official AY chip, it is sold out on arcadeshop.com. Regarding the failure of my SGM, what else could it be, if it was the faulty CPLD, the RAM would not work, except it is not the case. Is the AY chip on a support? if so, it would be really easy for me to replace it. Makes me think, having to spend shipping costs for something that I can do myself. For the moment I am still waiting for a response from the email sent to opcodegames@dot.com Quote Link to comment Share on other sites More sharing options...

ricky Posted May 11, 2021 Author Share Posted May 11, 2021 (edited) I have sent my SGM to OPCODE for repair since the beginning of January 2021. I have just paid the final price for my second SGM 6th batch. Now I'm wondering if my repaired SGM will be sent with the new SGM ? I sent an email to OPCODE but I have no response.

I assume by now you got an answer from Grazi. I will send you an invoice for the SGM service, and ship with your new SGM. Thanks! Quote Link to comment Share on other sites More sharing options...
ricky Posted May 14, 2021 Author Share Posted May 14, 2021 I did not receive an answer by email from Grazi, that's why I am continuing on this topic. In addition I received a message from PayPal that tells me that the shipment has been canceled There I really wonder what's going on.

ricky Posted June 3, 2021 Author Share Posted June 3, 2021 Okay, well that's cool, I received a message from PayPal which this time indicates that the parcel has been sent. Quote Link to comment Share on other sites More sharing options...
