Ok, cool, thanks guys!  ;D I have a volt meter for my arcade cab so I'll use it when I get home...


Just be careful you test the right pins. I didnt!  :'(

I recently got my AV Famicom and plugged it into my Samsung HDTV yellow/white AV ports but the picture just doesnt seem right.
Colors look a little off, words/fonts are not clear/sharp, I changed my video settings on my TV to no avail.

Are these just not meant to play on HDTVs?
I figured I had the AV ports so its should be no issues.
Any thoughts would be appreciated. Thanks.

Nope none of the older consoles work very well with HDTV's. Best thing to do is buy a large CRT to play them on. I have a Samsung HDTV and it plays with a broken yellow line towards the left of the screen.

Maybe the scaler on your HDTV is doing some iffy things to the video signal (the Famicom outputs a progressive video signal, your HDTV may think it's interlaced and it's trying to do some weird field composition to it). Try your AV Famicom on a standard CRT TV to discard a problem with the system itself.

Its a general problem with HDTV's as far as I'm aware, never seen one that can run them perfectly.

Another problem with my Twin Famicom :( When I insert a disc it clunks twice and then I get a Battery Err 02 message. Which means the batteries are dead. Except its a TC so there isnt any batteries  :o Any ideas? It must be getting power to the drive as it wouldn't clunk to try and access it. Does the same no matter what game I use.

My AV Famicom was working fine when I got it, but it seems quite fussy about booting games.  I've found that I often need to push the cartridge at an angle a bit.  After a game boots if I stop pushing it often has graphical glitches or more often than not will just freeze up.  Is this a problem with the cart connector?

I had to put the console upside down to hold the cartridge in place so it doesn't crash to be able to play splatterhouse :(

Try cleaning the contacts on the cart connector and look for bent contacts and fix any you find. And if that doesn't work, check for cold/broken solder joints on the cart connector to the board. If you find any, re-flow the solder or re-solder them.

Well I really have no idea when it comes to soldering, but what's the best way to clean the cart connector?

Ethanol or Isoprypyl. Dab some on a cotton bud and away you go.

An old toothbrush is better than a cotton bud for cleaning the cart connector. Dip the toothbrush in alcohol and scrub the connector vigorously. Wait for the toothbrush to dry and scrub again, this will make the contacts shiny & clean. Repeat as necessary.

Also if you've got an air compressor, blow some high pressure air inside the cart connector, there may be stuff trapped inside. Otherwise try to bang it against a hard surface a few times to dislodge whatever might be trapped inside.

Anyone?  :( I might be able to get my hands on another Twin Famicom but I dont really want to throw this one away if I can.

Take it apart and check that the disk system is getting the correct voltage. Could be something as simple as a bad voltage regulator, cap, or cold solder joint.

Are those easy to get and replace?

They are pretty easy to get, especially in the US, but I'm not sure where you're from. Anyways, they shouldn't be a problem to find anywhere.

You'll have to check out the Twin to see what's wrong first, though.  :P
You might not need to replace anything.
