Re: Samsung T200 constant on-and-off



Unfortunately monitor has returned to previous behavior after being unplugged for 24 hours.

It's the same 5 second picture and quick reset but now it shows sporadic analog/digital connection search after several resets....

Re: Samsung T200 constant on-and-off



Thank You for an explanation @1supertech, after removing the solder I've found that about a half of the tab remained so I reapplied the solder again covering more surface.

Made DC output voltage readings (stable through the whole on off cycle):...
