    thx for the reply!!! *goes to the page on the link* and...what do you mean by "and your system could do with a service"? o.o
    well, i don't use OFFICIAL sega adaptors, but those supply both (tested with analog and digital multimeters) 9v/1.2A, and the sega genesis performs quite well, so that's not the problem i think...i tested the sega cd parts (transistors, ALMOST all capacitors (there are like 30 @__@), etc) and all that i've tested are in good shape and perform as they have to...i even replaced the fuse (because it was not useful, didn't work)
    i think that the BIOS chip could be f*ck'ed up...could this be possible? o.o

    i mean have you tryed to clean the system contacts on the sega genesis
    part where it conects to the sega cd that could be at fault
    i mean by service is i would fix the system and than replace the back up ram battery and check everything out i have done a few in my time.
    take care.
    I have all the bios fix in tool at hand.

    oh, yes! i have cleaned the piano-like contacts in the genesis and the input in the sega cd...i tested it with a multimeter and yes, there is conductivity between the sega genesis and sega cd pins...each one of 'em
    and the battery was replaced, no results =S
    very appreciated, well...i wouldn't have a problem with put the sega cd in your hands for being repaired...i live in chile (south america), i can send it to you...the thing is how do i pay you then? o.oU
    thx for the reply in advance!!!

    well, several months have passed since this problem i haven't been able to solve, i gave up in that time, and i wanna keep up with fixing it...because i haven't that money to buy a new on internet (because buy one that ships to chile is expensive, the shipping is more expensive than the console itself D: ) or even to bring it to service...so i am thinking now on replacing all capacitors (i tested them all in september and all "seemed" to be alright)...could that fix the problem? =S
    since the fuse that i replaced RECIEVES voltage and the regulator (it isn't the typical 7805, is a NEC 2605) receives 8 and gives 5 volts and the filter receives and give voltage...i can assume that they AREN'T the problem =S
