I encountered an odd problem with my Sega Genesis. Normally, when I
turn the system on, even if there is no cartridge inside the system,
the screen turns from blue to black. It doesn't do that anymore; it
stays blue, and there is no change at all. I tried using different
adapters, but that didn't work. I tried switching TV's, but that didn't
work. So, I bought another one off Ebay, and I have the same problem on
both TV's. The Genesis came with new adapters, except a Genesis power
adapter, so I used another one. The new genesis came with a broken RF
adapter [It won't fit the slot], and a Composite adapter that fits. The
only thing that I had to re-use was the power adapter. What could be
the problem? The red LED on the genesis turns on when I press the power
button, so I don't think power is a problem.
I encountered a similar problem a few years ago. The television that I was using did not have a coaxial (cable) line, so I had to us an adapter I have purchased at walmart to change the R/F adapter to RCA style A/V. Turned out that the problem was that this was bad.
So, My guess (given that you have used two televisions, and two different SEGA Genesis consoles) that thr problem would have to be something between the two that they would have in common.
My only other possible solution, would be that maybe the A/C adapter is functioning, but not properly. You could test it with a digital multimeter to make sure, or replace it with a universal A/C adapter, and adjust the voltage to 12 volts.

Well take all your game cartridges clean inside on the chip board thing you see that connects to system to make game play..take rubbing alcohol with q tip clean them all both sides .let dry bout few minutes..make sure console ain't dusty kinda blow it out a little...mine do same thing when stored..after games clean keep trying them ..it will get them to start working ..good luck
Sounds like the cartridge connector inside your Sega Genesis is dirty. You'll need to clean the connector AND clean all of your cartridges with rubbing alcohol. Cleaning this connector should be no big problem. Make sure your Sega Genesis is unplugged before you try any kind of cleaning or repair.
To clean your cartridges, simply use rubbing alcohol and Q-tips to scrub the connector pins clean. You will notice lots of dirt coming off onto the Q-tips. This will take many Q-tips.
This is important! Once you clean your cartridges, you still need to clean the connector inside your Genesis. Here's how:
First, get a can of compressed air. Blast air into that cartridge connector to remove any loose dust, dirt, or debris. Chances are, you'll still need to clean more.
Second, Use Q-tips to apply rubbing alcohol to one of your clean cartridges. Insert and remove this cartridge repeatedly.
Third, dry off your cartridge with clean q-tips.
Repeat steps two and three over-and-over until your cartridge slot is clean. Remember to give your Genesis time to dry before you plug it back in.
Bonus tip: If the above method doesn't get your connector totally clean, try wrapping a thin piece of cloth around an old credit card. Apply rubbing alcohol to the cloth, and scrub away at the cartridge connector.
Forgive me if this sounds condescending, but it bears repeating. Please make certain to unplug your Genesis before you attempt to clean or repair it. Safety first.
You may have a dirty cartridge in your hands, try cleaning the contacts with rubbing alcohol, use a cute tip and let dry, then try again. If still problem persist try to clean the console itself following the same procedure, best of luck.

This is pretty common. The games just need a good Q-Tip cleaning, and then the weird clean pencil-eraser rubbing.
Get out a Q-Tip, and rub it inside the game, on the copper part (The part you stick down into the system.). Keep doing this with new Q-Tips if the old ones get soiled with black stuff. After the new Q-Tip comes out white, it should work.
Sometimes, that isn't enough. Use some Windex or any other rubbing alcohol, dip it onto a Q-Tip, and rub it onto the copper part. Then, use a dry Q-Tip to dry it off, and let it sit out of it's case and out of the system for about 20 minutes so that the alcohol dries.
If that doesn't work, use a pencil with a clean pink eraser at the tip. Rub it inside the game, and use a Q-Tip to get all of the eraser shavings out. This breaks the electro-static cling/friction made when the game is being read by the system.
And if none of that works, go on Amazon or Ebay or to the store Slackers and get new video and AC wires for the Genesis. Sometimes that's all it needs!
I really hope this helps!
If the screen changes (From snow to black or something) when the console is turned on it sound like the console is partially working. Try cleaning the Cardridge pins que tip and some sort of cleaning fluid.
Once this is done insert and eject the cartridge several times then repeat the cleaning process on the cartridge. Hope this helps.
As I had just a similar problem with my MegaDrive/Genesis maybe this helps: Try an older TV set. I am not joking. It might very well be the case that newer TV sets/high-end TV systems can't handle the signals of the older video game systems. I have a 100 hz TV set and whereas there are no problems with a SNES, with the MegaDrive I just had a black and white screen with bars running through it. On a 60 Hz TV set this problem does not occur. Keep in mind that there were no 100 hz/HDTV sets around when these video game systems were in general use.
Actually somethign like that happened to mine. you might want to try to place a piece of paper in the front of the cartridge that will make the cartridge stay all the way back this is due to the fact that some of the connectors were messed up and had to be extremely close to work.
