Atari 520 STM with video issue (bars and waves)
Posted: Wed Aug 22, 2018 7:45 pm
Hi all,
I wonder if someone could help me.
I have an Atari 520 STM with 1MB RAM upgrade and TOS 1.04, it is connected via SCART cable to a SAMSUNG LED TV / Monitor.
The green background colour of the desktop has a wavy pattern, all games show "jail bars". The black and white image looks
good, the same for monochrome via VGA cable. Could someone kindly tell me what the issue may be?
I have tested the 520 STM via TV Modulator the outcome was the same.
I have also tested on different monitors, the image looks (almost the same).
Thank you in advance!
