Please someone help about this :(
Is the MT 999 a discrete clone, with separate CPU/PPU chips? It's probably noise from a bad design, but if it has separate chips you might be able to try some of the suggestions in the AV mod thread:

820uF cap between PPU pins 20 and 40 was suggested as a possible fix there.
Mt999 is a NOAC.
First step - replace power board caps (before and after 7805 voltage regulator).
Second step - add a 220uF cap between board and video cinch (desolder cinch center pole from board, solder cap + side to board and - side to cinch center pole)
