I took my nes apart, reset the pins, then was going to disable the lockout chip. Except that every tutorial my board looks nothing like the NTSC boards, I decided to search farther and came across european guys disabling their lockout and their board is IDENTICAL to mine! Can someone tell me whats going on? I will post a pic of the board. Even though the sticker says NTSC its not like any other NTSC board ive seen. The board also says nintendo 1989 on it. Thanks (P.S.) The reason all this is happening is because i bought the system, bought a tetris game to test it, cleaned the game, popped it in, blinking red light blinking white screen. Took it apart, cleaned the pins, reset the pins, everything was clean, pins werent bad at all, retried it, same thing. Decided to take the next step of disabling the 4th pin and stopped dead in my tracks. Im lost. I connected the system with rf, and then av and same thing. Im not sure if this is the right place to post, but considering i am kinda newbie but not expert, im in between, i need help. Thank you.
Your NES is NTSC.
There were 11 different revisions of NES motherboard. It's not surprising that the guides you were following did not exactly match your NES. You should still be able to locate and defeat the lockout chip.
Really? That mainboard claims to be a NES-CPU-08, which is a fairly typical one. It looks almost identical to my NES-CPU-07 mainboard.
As far as PAL/NTSC: You have a 2A03G, a 2C02G, and a 21.47727MHz crystal. That's NTSC.
awesome thank you for the replies. But i am stuck and havent the slightest clue what is causing the blinking. The power adapter the guy gave me, (i bought 2 nes, 2 power adapters came with, one covered in electrical tape and the other i dont know from where), my question is what happens to an nes when a power adapter is either over powered or underpowered. The 2 power adapters he gave that werent authentic say: input 100-120V-60hz,0.4a output +12V - 1.25a
The 2nd:model no, DV-1280-4
input 117vac 60hz 16w
output 13vdc 850mA
This guys is where i get lost. I am not good when it comes to electrical components
The red light blinking is always caused by the lockout IC (labelled 3193) not handshaking. Which is usually due to a dirty or otherwise problematic connector.
