SMS VA3 bottom oversacan dots
Post Posted: Sun Jan 02, 2022 10:00 pm
Hi at all,

i have restored a VA3 SMS with many cold solder joints.
At the first power up, i note on the bottom of my tv set,
a colored dots, this are really tiny.





This is a faulty of the RAM assy, or is normal
overscan of the SMS?

I'm using a SMPS universal supply.
Not linear one.

Thanks,

Toshio

These are totally normal.

They appear when the colour palette is updated apparently.
