I'm no EE but I've watched enough ElectroBOOM and Dave Jones to know why the DC adapter masks this. The AC adapter outputs the same 60 Hz (NTSC) or 50 Hz (PAL) sine wave form the mains power has. The FULL BRIDGE RECTIFIER in the NES converts this to a series of half-sine bumps, which the filter capacitor(s) smooth into a roughly flat DC to power everything in the system. If the filter caps have gone bad, the DC produced will have significant ripple, which is probably what's triggering the wavy lines. By using a DC adapter, you supply your own FULL BRIDGE RECTIFIER and good filter caps, so what goes into the NES is already smooth DC and so the inadequate smoothing doesn't affect it. So, replacing only the caps in the power section should be enough, and using a DC power brick instead of recapping is actually sort of a proper fix rather than just hiding the problem. However, the other caps in the system are likely on their way out too and it's just a matter of time before they fail, so yeah it's really best to replace all of them.

The trick with desoldering the RF-Modulator without ripping pads is to desolder the pins inside the RF-Modulator rather than on the main board. The pins on the main board have a lot of solder on both sides of them, and it's almost impossible to desolder them without having a lot of solder remain on the unreachable bottom side. Also the dark stuff on the RF-Modulator board probably isn't flux but leakage from one or more of the caps. Would also explain the smell. Usually, these rarely leak, but it CAN happen.

@BorderlineOCD

3 жыл бұрын

I plan to experiment a different approach on the next NES build to see what works best. I'm sure there's an easier way.

Thanks yesterday I check my NES and see that issue, now I know what to do

You always want to desolder the pins from the single-sided RF/power board since the motherboard is double-sided and the RF module is a huge thermal load for the desolder iron. If you do desolder from the motherboard you need to give it much more time to make sure the heat has soaked through and flowed solder on both sides. Yeah, leaked electrolyte always smells like fish when you heat it. I have yet to find an NES RF/power module without at least one leaked capacitor, even if you can't always see it. The three on the mainboard, on the other hand, are always fine. It seems that Nintendo used better caps/engineering than Alps or Mitsumi (the two suppliers for the RF/Power module). Most variants of the RF/Power module can be fully recapped without removing the whole thing but I always seem to run into the one that has a single electrolytic in the opposite corner from the main filter cap. :( Still, if you can avoid desoldering it, that's always best/safest. Huge waste of braid and effort if you ultimately didn't have to.

@BorderlineOCD

3 жыл бұрын

Great feedback, thanks for sharing your own experience. I had that capacitor on the other end of the board, but it looks like it's part of the RF audio circuitry. I might ignore it in future recaps and try the method you propose but not my favorite option to leave an old cap in there.

you could use little bit of clear nail sealer to cover your wire to help prevent shorts with a bridge that small.

It's easier to replace the capacitors if you leave the RF unit attached to the board, remove the one fully exposed cover and bend the other one open. The long legs of the new capacitors will reach the through holes with some creative tweezer work.

looks like the T-1000 sneezed on the mother board.

8:08 it’s because of what you just said. The caps are capable of storing the same amount of energy. But not able to deliver it in time. With a dc signal the voltage is not changing and the caps are not being asked do deliver a changing amount of charge. In fact they don’t do anything once at a steady state (for ones acting as filters) so the problem goes away

It depends what solder you use as they have different melting points. The ground plane on the device also plays a role as it can suck up a lot of heat its if a big ground plane. I find 350C or 375C to be a good sweet spot with my setup for most jobs. I lower it for sensitive work, and every now and then crank it up if the job demands it. I would suggest doing some practice on a junk board if you haven't used your iron much yet to give you a good feel for your iron and the products you are using. Just remove some random components, clean up and re-attach them.
