Samsung UN50J6200AFXZA - One side of LED's not working?
Complaint was no display, confirmed and I saw
this series USA model is very prone to backlight failure, so
ordered (8) new strips. Opened up the TV, and am testing the old ones. So
far all the ones on the right side are lighting up ok,
the set of strips connected to them via the connector side with the plugs
are not lighting up at all, even when I supply power directly
to the pins on that side.

I took out a set of the new strips, connected them together and tested, and
they are doing the same thing...whats going on? Thought these were all in
parallel.

If I separate the strips, the one with the connector plug seems to not
light. I have not gone through all the
new ones yet to test. I suppose they could be defective but strange how all
the ones in the TV on that side are not lighting and the others are.

Anyone have an idea whats going on here? indecision

Samsung UE40F6340SS tévé ki/be kapcsolgat (megoldva)
Sziasztok! Nevezett készülék bekacsolást követően (kép nincs) indul pár másodpercre, majd visszakapcsol készenlétre és újrakezdi. Háttér egy pillanatra felvillan. Sajnos olyan rövid időre, hogy mérni nem tudtam a feszültséget. Többi feszültség rendben levőnek tűnik. Háttér rendben. Felvillanáskor olyan, mintha túl nagy lenne a ledekre jutó feszültség, bár ez csak "megérzés". Ismeri valaki ezt a táp/meghajtó panelt? Vagy nem is ez okozhatja a problémát? Köszönettel: Kiss Z.
