We have made another VGA-SCART cable for the ArcadeVGA, which works perfectly with an old 14" Sony TVset, but not with a Daewoo. Actually, the picture is good, with perfect colors etc but there's a flickering every now and then, like loosing sync or something. It happens all the time. We thought it could be a problem with a bad soldering, but since it works flawlessly with the other tvset, it has to be a problem with the TVset. Anyway I could fix this, that means not buying another tvset?
