When I select a game and the game screen appears a few seconds later the screen gets jumbled and I hear a loud screech. What could be the problem?

Do you have the cart mod installed?

[bradhig]

No I just got it today. It was working fine and then it started acting up. Some games work like secret quest ,but others just give me the garbled screen when I select them.

That's weird, how do you got it hooked up? And what kind of TV are you using?

[bradhig]

I have it hooked up to an HDTV tv through a video game switch box. The screen goes bad like an Atari 2600 with a broken cartridge in it. Could something be shorting out.

Good troubleshooting would dictate that you try it on a different display and plugged directly into the TV. Try a CRT TV if you've got one.

Make a list of the games that are garbled and pay attention to if they are the same ones every time.

Push all the buttons on the device and see if anything changes - switch the B/W switch too.

I have done all that but we don't have a CRT tv.

I have an older flashback 2 that works just fine with this TV. I got a flashback 2+ for the bugfixes and the new games.

I guess I will have to order another one.

I have a jumbled screen problem after my cart mod. Does your jumbled screen look like this:

[bradhig]

Yes it does.

[wongojack]

So it looks like that, then you select a game that works with the joystick and it fixes? I guess the menus work for you?

[bradhig]

The menu works. The games keep giving me that messy screen when I select them and go to the game screen.

[bradhig]

I ordered a new one. Selecting a working game doesn't fix the problem for the other games.

[bradhig]

It's the left controller port that is causing the problem. When I wiggle the joystick connector around the picture sometimes comes back for a short amount of time Why would a joystick port mess up the video signal?

Are you using the same cables for the other flashback 2?

[wongojack]

/\/\ I don't understand that question, but there is a lot going on right above the DB9 port. Its possible something on the board is loose.

The jumper that determines if the device will be ROM or cart is right above that port - for examp;e
