problem with model 2 genesis

[zetastrike]

I've had my model 2 since August and it's starting to have some problems. For one thing, the picture tends to flicker and get jumpy if I move the system when it's on. There's also a very pronounced buzzing noise in the background of some games, mostly when the screen is showing bright colors, but my model 2 is a VA 3/4, so it shouldn't have any sound problems. My one guess is that it might be the RF cord because when I got it, the pins were all bent out of alignment and I had to straighten them with pliers. Also, when I touch the part of the cord that plugs into the system, the buzzing gets quieter or stops completely. Should I just get some composite cables?

Take the unit apart and reset the solder points where the RF connector meets the main board. That should do it.

It definitely sounds like a bad connection somewhere. From the symptoms described, it could be in the mini-DIN plug of the RF modulator (in which case the best plan would be to replace it with AV cables) or in the mini-DIN jack's connection to the Genesis mobo (which would most likely be a cracked solder joint; reflowing all of the connections between the jack and the mobo would fix that).

Well, I found my sega megadrive 2 and ain't played it for 9 years, but I connect the official rf unit for the sega megadrive 2 into the tv, I put the 9 pin cable in the sega megadrive, when I switch on my sega megadrive 2 the screen flashes, this is how I know I have connected it properly, when I am tuning in on different channels, I auto fine tune and my tv never comes to a blank screen, it just dont want to pick it up. Is there some way I can make this come to the blank screen? I need help....
