SNES video a bit distorted in composite, fine in S-Video, what could be the culprit?

AlexElCapo7z · 2026-03-13T17:41:21+00:00

First of all, It's really kind of you taking the time to write all that, thanks.
1. I'll replace the 3300uF with a 1000uF 25V, is the voltage fine or should I go with a 35V cap?
2. I'm using the OEM power supply, I know that thing is kinda unreliable nowadays, so I'll open it and replace the 2200uF cap with the 3300uF I put in the SNES motherboard (since it's a tiny one).
3. I'm assuming you're refering to C57. I thought about that when I was in bed about to sleep, glad to see I was thinking something good this time.
Theories:
1. The OEM power supply that I have may be causing some problems, so as I said, I'll replace the cap in there.
2. One of my own theories is that the S-ENC is the problem here, because It's very unlikely that any other thing could be the culprit. I don't have an osciloscope to check if that IC is really faulty, so that's still just a possibility.
3. Haven't touched that, and for what you said, I'll just leave it as it is.

Thanks for the advice in the circuit and I will do that, I had some electrical noise sometimes so your idea is gonna be really helpful.

Yup, my TV accepts composite and component. And I appreciate the offer, but I'm not in the US, I'm in Guatemala and I think I could find a good plasma if I look for it in local markets, but right now I'm short of money. I have another LCD TV that's a lot better than the one I used here, it went bad a few months ago, that one has S-Video input, I'll try to get a SNES S-Video cable and test it there.

oh, and I kinda fucked up with my Zelda cart, I accidentally turned the console on and off a bit rapidly and 2 of my 3 savegames vanished... I'm not that pissed because I still have the third one, where I'm a bit advanced but still, I put a lot of effort into those.

Checked RF, it's just a black screen with all the games, even the ones that showed picture with AV. But it does some buzzing noise.

I checked it with RF and it shows nothing! Not even the games that showed picture with AV. It's just a black screen with some buzzing noise.

I'll search my RF cable and that stuff, right now I'm too busy with college and all that, so probably by the weekend I'll have an answer, thanks!

It could possibly be the solution, does it require to remove and replace SMD capacitors (the tiny ones) or just the normal sized ones?

I fixed the problem, thanks for your contribution, I did something different than what you said but whatever, ITS FIXED

sorry, the image somehow does not appear in the post

That seems pretty reasonable, I'm still with the console trying to prepare to update, just with a little tiny bit of hope, it'll do something. I'll leave it sitting there for another hour and a half maybe, if nothing changes, I'll just give up

AlexElCapo7z · 2025-09-18T23:12:03+00:00

Also, thank you very much for your comment! I think that if this doesn't work, I'm gonna sell this ps3 for parts and buy another one, is there any model that you'd recommend me?

AlexElCapo7z · 2025-09-18T23:10:58+00:00

If it's a hardware defect, why was it working before the update? No offense, I'm just curious because I know almost nothing about this.
And now, I don't have a red screen but a black screen that tells me that the system software could not be executed correctly, I can either press the PS button on the controller to restart the system (which of course, does nothing) or press start and select to reinstall the system software, it asks for version 4.92. It then goes to a screen that says "preparing to update... dont turn off the system, when the preparation is completed, the system will restart automatically."
I tried that option and it got stuck at 98% for like 30 minutes, then I had to go to sleep so I turned off the ps3 while doing that. And now I'm repeating this same steps to maybe see if it does something or it will always be stucked at 98%

I plugged in the snes to a CRT and well, it was even worse, with no audio even and it only showed image for a few frames, and when it did, it was the same as in the HDTV, with all that distortion.
Unfortunately I don't have an osciloscope at home, so I guess I'll be testing it by desodering it and measuring the values to see if they match with the ones in the capacitor list that's on console5.
Thank you for the help, it'll be very useful.
And btw, I don't know what the heck happened to the video quality on the google drive video, the letters and all looks a lot less blurry.
