|
| hi guys been working on 3 ps50c97hd samsung tvs.
all tvs had no picture due to blown top buffer and y-sus. i repaired all 3 ysus on all 3 tvs and tv now powers up by just trying lower buffers which were ok as only top had shorted. however on all 3 tvs im getting a strange green dot type pattern? this happens on all 3 tvs. on first thoughts im not convinced its still the ysus as all 3 are acting the same and all 3 tvs are using a different y-sus & bottom buffer. and were repaired by replacing the blown mosfets. anyone have any ideas as its strange this is happening to all 3 tvs which the ysus was repaired. i have checked vs.va. scan all all voltages correct. http://www.youtube.com/watch?v=AKus6DnrorA heres a video below showing problem. has anyone come cross this problem. thanks |
