|
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.

Indicates the Y related parts blew because of bad panels. |
