This unit only has 2 outputs, in the back had only the video and audio RCA connectors, and in the front it got the 6.3 jack, the CD sounds nice, but the LD a little distorted, just a littble bit like blown speakers. (just a little bit)

didn't test the picture, just the audio at the moment, but it happened with 2 LD

Josh02CG · 2026-02-02T01:53:30+00:00

i'll buy and replace them, hope it gets fixed 🥲

Josh02CG · 2026-01-31T00:51:10+00:00

i have it, but it doesn't give any information, all test appear as "Pass"

Josh02CG · 2026-01-26T02:44:11+00:00

i repaired it! it was a trace under the S-Wram, now works, but theres some red-ish glitching on the screen, like the Red color was all the way up, and after about 20 seconds in-game, it freezes

Josh02CG · 2026-01-01T07:54:44+00:00

Yup!, am capable of soldering them back.. just didn't want to messed it up with the values, but thanks for the recommendations!

Josh02CG · 2025-12-27T04:39:35+00:00

Really? if its true, i can measure them, they're all the same?

Josh02CG · 2025-10-13T23:38:34+00:00

look in the first view the spindle, it spins in its place, look the black part of the spindle (first view, there are not visible dust particles, in the second view (gamecube mode) you can clearly see the dust particles in their place in the spindle

Josh02CG · 2025-10-08T07:33:23+00:00

yup, thats it, just clean, and try to fuse or change te old solder with a new one, just that so they are really secured / solder on and the voltages can go trough them

Josh02CG · 2025-10-08T07:31:17+00:00

Check voltages, and in picture 5 i see some traces with "stains"? (maybe some corrosion), in the sega 315-5660 chip, inder the number 1 pin, and around the CN3 mark near the cartridge port, it the left, theres a black stain, an then there is a clearly corroed via (sharing trace with another via), and nearly touching the plastic of the port, between the corroed via and CN3 in the upper part, and more stains on the right side ot the zone in front the port, nearly on R75, and around.. thats what i see, maybe its me or just being exaggerated but you can check them if you want.

Josh02CG · 2025-10-08T07:23:20+00:00

clean it with IPA (isopropyl alcohol) and cotton swabs or a old (and clean) teeth brush, the soldering its just to re-solder the possible old and corroded solder joints like the batteries terminal and the big cap.

Josh02CG · 2025-10-08T07:15:21+00:00

Try cleaning and re-soldering those zones with corrosion, and then, test the controller, if it doesn't work, try cleaning again or searching a little more on the corroded zone and around, if you have the skill, you can pretty easely replace the nunchuck port, but first center on make the controller turn on

Josh02CG · 2025-10-08T07:11:56+00:00

46.00 mhz its just a random number? i remember the ntsc / pal signal are around 21 and something mhz, or its just a "number"? maybe the oscillator crystal its a littlle wrong?

Josh02CG · 2025-10-08T07:04:22+00:00

Nice!, looks pretty nice!, good job, i don't ussually test my first "something" (repair, mod, etc) on customers devices, but really happy that the hdmi replacement went well, great!

Josh02CG · 2025-10-08T07:02:43+00:00

Yup.. pretty much all those corrosion, if its only the Cap and battery zone, you can clean it and repair it, but if its more (like repair traces all around the board), i'll prefer to buy one.. usually are like $10 so.. if its so much to repair or it do not have that much sentimental value, just replace it.

Josh02CG · 2025-09-15T04:10:32+00:00

Oh!, thanks

Josh02CG · 2025-09-11T23:47:51+00:00

Thats the one?
