AndersE Posted March 11, 2016 Share Posted March 11, 2016 I got a display that both have the ghosting lines AND flickering pixels (like stars flickering). Do i have bad luck or what? I will try another powersupply soon. Link to comment Share on other sites More sharing options...

Rappelbox Posted March 12, 2016 Share Posted March 12, 2016 What kind of powersupply did you use? Seems that some are not providing enough power or some other issues. Normally I check all displays before they are shipped and I sort bad panels out. But always keep in mind that bleeding is a known issue with these panels.

Content Provider lucky1 Posted March 12, 2016 Content Provider Share Posted March 12, 2016 I also heard of the flickering pixels being solved by grounding the display and controller. Link to comment Share on other sites More sharing options...
AndersE Posted March 13, 2016 Author Share Posted March 13, 2016 Yeah, i suspected it was something with power or grounding, i have not yet installed it properly, just powered it from the play pc's powersupply (500w supply). So i don't think there is some major fault I have some time until the cab is ready to install it into. Is there any better instructions on fixing the bleed than the link to that german guys fix? I am pretty good at surfacemount soldering (10 years as playststation modder , or atleast i was before the near-sightedness came (i'm getting old;).

AndersE Posted March 15, 2016 Author Share Posted March 15, 2016 I have had the board under a big magnifyingglass now, and i can clearly see that the led is loose (when poking it with a needle) plus that someone has soldered tiny tiny copperstrands to the led from the led besides it. So i guess the coppertraces on the board is toast, that's why the soldered strands. Heh, even my phone (G3) could focus on the thing, so if anyone want to see themselves i can upload a pic. So there is nothing i can do or dare to do. I don't really care, but it is sad, there could have been a better preshipping check of panels I am orderering new panels myself from china, and hope that one atleast is ok. Now i just need to figure out how to get color dmd's in pinballx (they play b/w now). Link to comment Share on other sites More sharing options...
