  I&apos;m no EE but I&apos;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&apos;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&apos;t affect it.<br>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&apos;s just a matter of time before they fail, so yeah it&apos;s really best to replace all of them.

  Small hack: use flux with your solder wick, it will work even better

  When my daughter was born in 1994, I sold my NES, Super NES, and Genesis CD, because I did not use them enough, and we needed the money.<br>I kick myself all the time for not keeping them, and finding money elsewhere. :(

  In my case, replacing the capacitors did not help with the rolling waves. The real problem turned out to be the power regulator. Once I replaced it, the video interference disappeared completely. So even though the capacitors were old and worth replacing, they were not the cause of the waves in my NES.
