@bartl68: any pics or documentation of that mod? Did you use a resistor to fix sound on this 3rd slot?
(sorry for the off-topic question, but I have some slot-connectors laying around from a broken 8250, these might be useful for a 3rd slot in my 8280)

i also have the same problem before, but i fix it like using 2 transistors (value 2,3 Ohm) from the pin 49 leg of the cart to the pcb, with good results!!

see link : http://www.mijnalbum.nl/Foto-NPHJDBPA.jpg : notice the red circle !!!._,

i remove this picture with a better one

Sorry but I can't understand this picture. I should solder one side of both resistors together and the other side on pcb of cartridge connectors number 49? What's red cable used for?

Well guys, it seems that my Sanyo 70FD suffers from the same problem of the Philips regarding the MegaFlash SCC+. Would be any problem to make the modification (22K resistor on the line 49 of the slot) directly on the MegaFlash card? Because I'm not happy to cut pin 49 on the Sanyo's PCB..

Thanks,
Daniel

If you're able to put a resistor there, sure, that will fix it. I've opened mine but there didn't seem that much space left on the PC to solder an extra resistor by hand. Then again, I don't solder much

Did you open the cart easily ? I don't saw any screws to open it. Hot to open without damaging the case ?

That would help me too? Any pictures of the open MFR? Again I also need soldering for dummies.

You just pull both halves apart. Yes, there is a change you'll damage the pin's that hold them together. It happened with mine. I just use some superglue on the pings to glue both parts back together. I'n not willing to try to open it again since I already glued the pins, so I cannot take pictures of the inside, sorry.

Creepy, I will try open mine. Thanks!!
