This is a fuse. Check it, maybe it's blown.

Do you mean the black bar?  Odd, never saw a fuse like that before.  Let me check it; normal ohms testing right?

Well I placed my multimeter on OHMS setting and one lead on each end and it came up with it was an open circuit.  I also placed the multimeter on DIODE testing and again open circuit.  Fuse might be bad.  I never tested it because I didn't know it was a fuse.  Where could I get a fuse to replace it; without spending more on the shipping then on the part?

Replace it with a fine piece of wire.

Replace it with a fine piece of wire.

Why a fine piece of wire; make shift fuse?  Does anyone know what the rating is on that fuse?  I wouldn't mind replacing it with a another fuse just in case something happens.

I can clearly read it from your picture.
You can solder a standard glass fuse holder and install a regular fuse if you like. But I wouldn't bother.

[wolf9545]

Well stupid me.  I am so used to not much being written on the items that I didn't even think of looking.  I will try soldering a piece of wire across the fuse so I don't have to remove it.  This way the unit can still be fairly orignal.

Hello!
I'm Looking for some advice and help...Anything would be greatly appreciated..
I've recently bought a Sharp Famicom twin system and replaced the belt. This system came with one disk game (not sure the name of it), after doing some adjustments to the motor, side "A" gives me error 23, while side "B" gives me the "A"."B". wrong side of the game error...Is it possible for the data in side A to be corrupted?...The game is not in the best shape either...Like I said, its the only disk that I've in hand at the moment...
Also, the disk drive head moves up and down 2 times before stoping while trying to read the disk, is this a normal behavior of a disk drive system?....Thanks in advance!..

That thing's a fuse?

Weird, just yesterday I was using a glass tube fuse as a DS stylus.

Replace it with a fine piece of wire.

Well I jumped the fuse with a piece of wire and YIPPEEEEEEEEE!  I now have a working, and in very good condition, famicom.  Thank you.  Also, just for everyone's knowledge my famicom works on my new tv (CRT) channel 95.

You've inspired me to take apart my non-working famicon and see if it has the same problem. It's the only thing I haven't yet tried.

Okay, I searched the threads but I found no answer to my specific question. I just got a bundle of games I ordered online and all of them worked great except for one disk. When I try to load it into my Twin I get the Error 27 message. I have 4 other disks that all work great including one that came in the bundle as this one. Does 27 mean my disk is screwed or could it still be my Twin even though all the other disks work?   (Err. 27 = Block end mark seen but ends prematurely) What does this actually mean?

Oh, I forgot to say I left the new 7805 (power regulator) in the unit instead of replacing it with the orignal.  I don't think that the orignal 7805 was bad but no sense putting it back in if everything works fine now.

I can't fucking believe it, but it fixed my Famicom. Mine works on channel 96 (CRT). Perhaps this is a very common problem with Famicoms?

[133MHz]

I'm glad that you fixed your Famicoms

[ericj]

I usually try to be pretty good about checking the simple things first. Doesn't get much more simple than a fuse. I never thought to check it because it looked okay.
Thanks for leading us down the right path, 133MHz!
