very odd problem with a 21" 21sz3E TV
This tv has only 1 composite and tuner inputs.
Suddenly something got wrong with its internal program and new inputs appearing when I press the input button! now there are 3 inputs and now I also have bass, treble, balance settings in the menu (that ofcourse not working, mono tv), but the real problem is that the tuner shows me actually the composite input and tuning doesn't do anything.
there were more problems, like the picture moved down out of the screen but I have managed to fix that through the SERVICE MODE and I hope maybe you know the settings that may fix this tuner problem in the service/designer mode

Thanks!
