Famicom HVC-001 controller 1 problem

[brutalex1935]

Hello, I have a weird problem with my famicom. ( just in case - It has Nintendo 1988 copyright sign on its board, but on the case it says that it is made in 1983). I have PAL TV at  home and was unable to play with RF cable, so I AV modded the famicom. None of the complicated ways worked out for me, so at the end I just soldered RCA wires right to the board where it says A V. Now I have very clear video and fairly good audio signal, but the problem is that the controller 1 all the time keeps pressing the d-pad buttons by it self and very, very fast like some kind of turbo button would be activated. I cleaned the board from dust, disconnected the controller 1 and when I switch it on without controller, there is no problems. Then I connected it back again and it still keeps pressing the d-pad. I don't know how to fix this. By the way, I opened up controller, cleaned it from the dust, still nothing.

It looks like the problem is only in the controller or it's cable. Try to measure the cable if it's not damaged/broken.

The 4021B shift-register may be toast. It's possibly also an internal issue on the FC logic board...

I had a similar experience with a gameboy color someone gave me that they picked up in a junk section.

Every button on the device was acting like it was on turbo, including start and select...   Strangely, I tried it recently, though with a different game, and it didn't seem to be doing any of that.  I was pretty sure it was a system fault, but could it have been the game in that case?   I haven't investigated further yet.


Anyway, I'm sorry, I have no idea what your problem might be.

I had a problem with a controller once. There was dirt (oxidation or something) on the circuit board of the controller that needed to be removed.

I've seen that before, but he said he already cleaned it. If he was in the US, I could sell him a replacement controller at little cost, but it looks as if he's in Latvia, and the freight costs would be more than the part.

@brutalex1935: What does Controller II do? Is it the same? 

[brutalex1935]

I tried almost everything. I also noticed a few things. When my original controller 1 is connected to the board, AC adapter gets very hot quickly. When controller is removed - everything seems just fine, adapter doesnt get hot. I cut off the Famicom controller's wire and according to schematic I found in the internet, I connected that wire to another clone system controller. Now this controller seems to be working fine with my famicom, except for controller's left d-pad button. It does the same function as "start" button - pauses the game

Seems like your controller has a busted 4021 or a frayed cable causing an internal short circuit.
As for your second problem, that's usually linked to mis-wiring of the clock and latch lines.

OK, very big thanks for the advice, now I just want to run one final test, but first I need to know is this correct:

Famicom controller wires

RED = STROBE (is this same as latch?)
ORANGE = DATA
YELLOW = CLOCK
WHITE = +5V
BROWN = GND

?

p.s.

can I use front 15pin connector for the controller 1 instead of using one on the board? because some clone systems can do that
