"Noise" with scart
Hi
i have a new lcd tv only for zxuno and cousins...
with vga i have a nice image... but with scart I have some "noise" running around the screen.
my tests: different boards, scart cables and also using an addon (multivideo addon) does this "noise". Also tried with different power source.
i tried now runing zxuno pcb tester v.10 and in pal i have that "noise" but with ntsc i don't.
but with bios .70, also if i choose ntsc, i get this noise... (lower bios and lower spectrum core I also have this problem)
Anyone had this problem?
Thanks

Chineses PSU they usually show that effect in RGB mode, but not all TVs reproduce this effect. Try not chinese PSU or unpulsed current.
