Quote from: FAMICOM_87 on February 09, 2019, 01:24:04 amyou will get a solid black screen even if video signal from main board and RF power board is disconnected, so get multi-meter and check it, also check if you getting good 5V out of 7805, you you getting lower then about 4.5V that might be an issue too .There is another possibility, bad RAM chips or CPU/PPU.Touch them to feel if any getting unusually hot during operation

As in check the internal cabling? I don't think it's a power issue (wouldn't it not output anything at all if the console wasn't powered? The screen is static when the system is off).

So at least audio is working. Seeing as audio works but theres no sound from the game, does this mean it's the cartridge? Or could something else still be bad?
