Very it is simple.
There is a PIN for video output in the video controller TMS9918ANL which is used in the m5 series, with the m5 it indicates that signal in the TV via the RF modulator. Because is, don't you think? the original signal should have been connected to the video output terminal of the TV that way just is.
Simply, the m5jr. Because sound is outputted the by way of the RF, with just this remodelling sound becomes unable to be audible. (Will try to remove by way of the sound tip/chip)
As for upper figure, m5jr. It is the same direction as the case where you saw from the front. Because the 36th PIN (the 5th) COMVID composite video output (the video terminal of the TV for home) is from the upper part left, it utilizes this signal as the line of central side of the video cable. Rather than taking from the foot of the IC, chasing wiring, whether the one which you take from the through hole is better, the しれません.
Because the line outside the video cable is the GND, the m5jr. Starting pulling the GND suitably from the baseplate, it can connect. It does not short-circuit, sea urchin note.
As for YC separation however it is the Imai ち, (with, necessity is), black has appeared to the game which utilizes blotting clearly.
Being something which was analyzed individually, being to do, it is non guarantee. After turning this data to the origin, it does not have responsibility altogether in regard to the trouble which occurs.
