lokidchser Posted May 7, 2018 Share Posted May 7, 2018 OK Inty experts, need your help with my "new" ECS that arrived this weekend. Hooked things up to test, and while the Inty II fired up and worked flawlessly, when I hooked up the ECS, the transformer brick emits a low buzzing sound, and the TV displays only a black screen. Is this a bad power supply problem ,or couls it be something more advanced? Quote Link to comment Share on other sites More sharing options...
Porte048 Posted May 7, 2018 Share Posted May 7, 2018 I believe an original NES power supply works fine, but I like to have dedicated power supplies. Here’s an ECS replacement: https://www.amazon.com/PHC-AC-091B-Transformer-2-5mm-Barrel/dp/B009B1EGZ4/ref=redir_mobile_desktop?_encoding=UTF8&psc=1&ref_=ya_aw_od_pi 1 Quote Link to comment Share on other sites More sharing options...

I'll try the NES power supply, just to see if that fixes the problem. Beyond that, I'll keep my eye out on EBay for an original. Quote Link to comment Share on other sites More sharing options...
mr_me Posted May 10, 2018 Share Posted May 10, 2018 Do you have a cartridge plugged in? Quote Link to comment Share on other sites More sharing options...
jaybird3rd Posted May 10, 2018 Share Posted May 10, 2018 I was about to say ... the ECS Computer Adaptor requires a cartridge, even if you only intend to use ECS BASIC. Quote Link to comment Share on other sites More sharing options...
lokidchser Posted May 10, 2018 Author Share Posted May 10, 2018 (edited) ok, sorry for the delay in responding...checked the ECS with a known working cart, and a nintendo PS, still black screen. Stupid question, is the supposed to be a 1/4 inch gap between the ECS base unit and the Inty II? They wont join any closer, and I dont want to force them if the gap is normal. When i press the reset, i get what looks like digital gibberish, but when i let go, black screen Edited May 10, 2018 by lokidchser Quote Link to comment Share on other sites More sharing options...
mthompson Posted May 10, 2018 Share Posted May 10, 2018 Make sure the cartridge port contacts are clean, just like you have to do with the master component. My ECS had a black screen until I worked a cartridge in and out several times to get the oxidation off. I really should clean it properly some day.

lokidchser Posted May 10, 2018 Author Share Posted May 10, 2018 (edited) already cleaned the ports, isopropyl and deyoxit. gave it one more shot, no dice Edited May 10, 2018 by lokidchser Quote Link to comment Share on other sites More sharing options...
m-crew Posted May 10, 2018 Share Posted May 10, 2018 Try connecting a Intellivoice into the ECS and game into that. Quote Link to comment Share on other sites More sharing options...
Intymike Posted May 10, 2018 Share Posted May 10, 2018 The Super Nintendo power supply works with the ECS (tested by me). Don't know if it has the same parameters than the NES one. And a photo how much the Inty II and the ECS are apart. 1 Quote Link to comment Share on other sites More sharing options...

And they both have the same characteristics: 9V 1.3A. 1 Quote Link to comment Share on other sites More sharing options...

lokidchser Posted May 10, 2018 Author Share Posted May 10, 2018 Try connecting a Intellivoice into the ECS and game into that. That did the trick. Any idea why that would be the solution? 1 Quote Link to comment Share on other sites More sharing options...
m-crew Posted May 10, 2018 Share Posted May 10, 2018 That did the trick. Any idea why that would be the solution? That means one of the connections on the ECS need more cleaning.. Quote Link to comment Share on other sites More sharing options...
m-crew Posted May 10, 2018 Share Posted May 10, 2018 I do that a lot when I take my ECS out because you got to love the train... lol Im glad it worked and you know your ECS is good... Cheers Quote Link to comment Share on other sites More sharing options...
lokidchser Posted May 11, 2018 Author Share Posted May 11, 2018 OK, got it cleaned enough to work without the Intellivoice module, so all is good there. However, I HAVE determined that the power supply is faulty. (works with the NES power supply, not with the ECS one). Now, here is the latest dilemma...I tend to be a bit anal about completion-ism for these sort of things, so is there anyone here with the knowledge to rebuild/repair the ECS power supply, or has a replacement factory power supply for sale?

I haven't tried to repair an ECS power supply specifically, but have repaired other types. But most times (including this one), you have to pry/crack open the plastic shell to get at the components, and you'll have a fairly messy looking power supply after that.
