Update. The orange Famiclone is actually PAL-B not PAL-D. I haven't done anything with it yet. I noticed the 9 pin controller port is not working and will look into that later. However, I have D30 xiaobawang 小霸王 (SUBOR) clone console from 2006. I'm going to try the conversion to NTSC on that. If it goes well I want to put the D30 board into the Orange Famiclone. There will be some miss-matching especially with the AV and power ports but I'll work around it. I could leave the D30 in its original plastic case but that case so cheap quality. In fact the ribbon cables between the cart-board and the power/AV board broke off because that cable is cheap quality as well.

Hmm, no... I just tried my own NES-E controllers on my Famicom AV and I can press diagonals just fine.
I do recall seeing a review on some replacement membranes stating that it became impossible to press diagonals with them in place, but... if they work on the PAL NES, then logically it has to be the console, somehow.
You say that they still work fine on your PAL NES? That would rule out that there is any problem with the controllers, it might be the Famicom. Unless there really is a compatibility problem with the E-model controllers that we don't know about.
If you have an adapter or flashcart that allows you to try the same games (1942 etc) on your PAL system, you could test that too.

Sorry but that doesn't make a whole lot of sense as it's both controllers with the exact same issue (not one dodgy one) and are the controllers I've had since I was a child that work just fine on the PAL NES. Also individual directions are all working and it's only pressing two directions at the same time e.g. up and right there is no actual diagonal input for it to press and these directions all work fine by themselves. I also refreshed the rubber membranes etc not long ago so I will try swapping them back see if that makes any difference but can't see why it would.
It sounds like the famous chip problem if it's a CPU01 or CPU02 first generation board....However, I like to go through a basic to more in-depth check list. Something that might seem complicated might just be a simple problem to repair. NOTE: This is what I would do if I were in the situation. Do at your own risk etc.
Basics 1) Check the AV cable (try another one if you have it) 2) Check with another game (could be a game issue) 3) Clean the test game cart pins with IPA and cotton bud/Q-tip (I use 99% IPA) 4）Clean the SNES cart slot with IPA (I do this with a new soft toothbrush) 5) Check the video port is clean and clear of dirt, dust, 6) Try the RF (if possible and if you don't have another AV cable) 7) Check it on another TV (if possible) Give it a smell. Does it have a burning smell? Is the unit feeling really hot?
After opening it up 1) look around the board at all components (are they all there, do they look ok and solidly attached to the board, how are the solder connections? how are the AV connection solder points?) 2) Really look at the capacitors for leakage/swelling (both surface and thru-hole) 3) Check for board corrosion especially around chip pins.Is the board ok? look at traces. 4) look at all the chip pins and see if they are sold (i like to take a clean DRY toothpick and VERY gently push on the pins to see of they are all solid and don't move)
After all that if no dice then I would move onto cap replacing...Chip replacing the more complicated stuff
