N64 RGB mod has horizontal scanlines + bad PSU
N64 RGB mod has horizontal scanlines + bad PSU
I RGB modded my N64 a while ago, and I noticed there are faint horizontal lines that move up and down and are very noticeable on white screens. I noticed them a while ago, but saw a post on it recently and decided to fix it. When I first installed the mod, I swapped a green led for the red one and extended a white led off of it to backlight the N64 logo. They both were rated at 3-3.2v drawing 20ma and I didn't attach any resistors, because I didn't know anything about leds, so could this have hurt anything? The lines persisted after removing the leds, but move up and down now instead of just up. The other culprit could be the PSU. It has always made a buzzing sound and smelled bad, like it's almost burning, but it really smells bad now so I think I need to replace it. Could the problem just be the power supply, and how should I properly wire the leds?
Re: N64 RGB mod has horizontal scanlines + bad PSU
Would it also be better to run the lights off of the 12v line and use the proper resistors so it doesn't introduce noise on the 3.3v line, and therefore the picture from the rgb board?
Edit: I opened the PSU, and theres a black burn looking spot in between two capacitors near where the N64 plugs in. They also get fairly warm when plugged into the wall but not connected to the N64, but that seems somewhat normal. It outputs 12.69v and 3.39v, so I'm not sure as to whether or not I should replace it.

About the PSU, probably should get rid of this thing and get a new one instead, a N64 PSU replacement shouldn't be hard to find.

What kind of RGB mod is it?

It's a Tim Worthington board.

Maybe the scanlines settings are "on"?Jordino wrote:It's a Tim Worthington board.

Re: N64 RGB mod has horizontal scanlines + bad PSU
my N64 also has faint moving horizontal lines, I didn't notice them until I set up a profile for linex5 on the OSSC
they are visible on a black screen more so than a white screen, they move at a speed that seems consistent with it being power supply noise
I'm assuming the PSU needs a recap or something but I haven't gotten around to it

Re: N64 RGB mod has horizontal scanlines + bad PSU
How do I turn it off? I can't find a mention of a scanline option being available. These scanlines are also more broad, and change speed for some reason.Lawfer wrote:Maybe the scanlines settings are "on"?Jordino wrote:It's a Tim Worthington board.
Do you recommend that I buy an oem supply off of ebay or get a 3rd party one?Lawfer wrote:About the PSU, probably should get rid of this thing and get a new one instead, a N64 PSU replacement shouldn't be hard to find.

Isn't this the noise that the additional power regulator board was designed for?:-

Re: N64 RGB mod has horizontal scanlines + bad PSU
Not sure, I know borti's board does it (the N64 Advanced one), but I dunno if Tim's board does it, at least not on older firmware.Jordino wrote:How do I turn it off? I can't find a mention of a scanline option being available.
OEM. I don't know if there are any reliable third party PSU for the N64.Jordino wrote:Do you recommend that I buy an oem supply off of ebay or get a 3rd party one?
Re: N64 RGB mod has horizontal scanlines + bad PSU
I didn't realize there was such a thing until now. I'm going to order it prebuilt off ebay since it's cheaper and easier than sourcing each individual piece. When I reconnect the 3.3v wire, should I solder it to the original 3.3v pad or the large one at the bottom near the cut off edge, or does it matter?Link83 wrote:Isn't this the noise that the additional power regulator board was designed for?:-

Re: N64 RGB mod has horizontal scanlines + bad PSU
The 3.3v regulator PCB is exactly what you need. The N64 has a notoriously noisy 3.3v rail that reveals it's self in the dac section of Tim Worthington's N64RGB design. It doesn't really matter which 3.3v pad you solder it to as long as you make sure to disconnect the old 3.3v wire. If you need one I have some made already. PM me if you are interested.

Re: N64 RGB mod has horizontal scanlines + bad PSU
Also, will attaching 2 3.2v 20ma leds in parallel with the proper resistors pull to much power from the 12v line? I don't want to ruin the PSU I'm getting.
Re: N64 RGB mod has horizontal scanlines + bad PSU
I find it funny Tim never revised that board to include the fix.
Really that entire half of the board should be 5v not 3.3
The THS amp drives better at 5v

Borti's boards made Tim's obsolete anyway.

They're more expensive and harder to buy though.fernan1234 wrote:Borti's boards made Tim's obsolete anyway.

I don't think he manufactures any of his old designs; instead releasing the design files for others to build themselves.Lawfer wrote: Does borti not make them anymore?
Tim's boards are more widely available at his own store and from the approved distributors.
Re: N64 RGB mod has horizontal scanlines + bad PSU
We'll be stocking them in Q4, fully Borti approved kits with flex cables and mounting kits.makar1 wrote:Lawfer wrote:

Which of Borti's kits will you be stocking? The power regulator and UltraHDMI+RGB flex, or just the regular RGB boards?BuckoA51 wrote: We'll be stocking them in Q4, fully Borti approved kits with flex cables and mounting kits.
Re: N64 RGB mod has horizontal scanlines + bad PSU
Wouldn't the closest borti's board to tim's board be the N64 Advanced board?makar1 wrote:Which of Borti's kits will you be stocking?

Re: N64 RGB mod has horizontal scanlines + bad PSU
Yeah it will be N64 RGB advanced.

Re: N64 RGB mod has horizontal scanlines + bad PSU
The equivalent to Tim's board is the N64RGBv1. The N64Adv is the version with most features incl. an on-screen menu.Lawfer wrote:

Are you still developing the flex cables for installing UltraHDMI and your/Tim's RGB mod in the same system?borti4938 wrote: The equivalent to Tim's board is the N64RGBv1. The N64Adv is the version with most features incl. an on-screen menu.
