Piucture fails without a reason

[TrueCrashB]

After playing for two hours the picture fails and the issue is now all the time.
I tested it with different Tvs.
I have no glue why.
Might it be a hardware defect?
Or could there be a problems with the soldering?
But it worked fine till it fails.

Have you tried to reset the settings? You can do that by holding the Start button down while entering the menu (LTrigger+RTrigger+X+Y+Start).

Yes, didn't work. Now there is no signal anymore. i'll check the soldering.
