docile tapeworm | 4,449 Posted June 17, 2020 Share Posted June 17, 2020 (edited) i paid to have my nes rgb mod. it randomly losses power completly. sometimes it will run for 5 min or it could run for hours but it always does it. complete loss of power no power light, nothing. after it loses power it wont power up. i have to wait (usually the next day) before it will power on again.

themisfit138 | 523 Posted June 17, 2020 Share Posted June 17, 2020 Is it a normal or top loader? I have the same problem with my top loader. Never have figured it out.

For $200+ you bet your ass I would.

docile tapeworm | 4,449 Posted June 17, 2020 Author Share Posted June 17, 2020 @a3quit4s thanks for the link. he said he replaced the voltage regulator. but mine is the frontloader so i wonder if it has the supplement regulator to go with it?

a3quit4s | 4,789 Posted June 17, 2020 Share Posted June 17, 2020 (edited) It could be missing since you said you played it for awhile and it’s just now acting up, the extra voltage pulling from the power supply may be finally burning out the power supply. I have exactly zero experience with that mod but it sounds logical. pics of regulator seem to be here Edited June 17, 2020 by a3quit4s 1 Link to comment https://www.videogamesage.com/forums/topic/4038-rgb-mod-nes-random-power-loss/#findComment-88367 Share on other sites More sharing options...

SNESNESCUBE64 | 677 Posted June 17, 2020 Share Posted June 17, 2020 (edited) I have two guesses: either the power supply isn't adequate or the 7805 is heating up and is going into thermal shutdown. Other than that maybe capacitors are an issue. Be careful with aftermarket power supplies, some of them are pretty bad and will not run it well. Overall, in terms of power there isn't much to the NES, so it should be easy to narrow down.

The supply should be adequate assuming it didn't crap the bed. I dont think that you need to put a fan, but maybe consider replacing the 7805 with a 78s05 as it is a more efficient regulator. First I would figure out whether or not that is the problem though. Pull the top lid of and wait for it to shut off and if it is hot to the touch, then it should be replaced. Just as a note, some people actually remove the heat sink off the regulator. If that was done, that could be the cause. But anyway, I think it's a heat issue, perhaps try another power brick, the original included power supply should be adequate from what I read, although I have never messed with any rgb mods. 2 1 Link to comment https://www.videogamesage.com/forums/topic/4038-rgb-mod-nes-random-power-loss/#findComment-88497 Share on other sites More sharing options...

That's cool, I wasn't trying to out the modder or give them flack either. I just thought if I knew who did it then I would have a better idea of what method they used and that might make it easier to figure out what is going wrong. It sounds like a cold or cracked solder joint somewhere to me. From the way you describe it. it seems like something is heating up, expanding, and a connection is separating somewhere. Then, after it cools back down, the connection is restored and everything works. If you think it's the switch you could just put a jumper across the points that the power passes through on the switch's connector and plug the machine in and let it run to see if this fixes it. The best way would probably be to pull the board from the system and run it till it shuts off, then test with meter to see where power is no longer flowing and follow that line back to the source. 1 Link to comment https://www.videogamesage.com/forums/topic/4038-rgb-mod-nes-random-power-loss/#findComment-90094 Share on other sites More sharing options...
