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?

Üdv.
A fenti tv típusa ST70 675 TOP.
A sorméret kicsi, nem szabályozható.
Szakadt volt az R569 (4R7), cserélve lett a TDA4950.
Cseréltem a sortáp szűrőkondit (100U250V). Átforrasztottam ami gyanús volt. Ha a sorméret potit tekerem a sorméret nem változik, de füstölni kezd az R569.
Ha volt valakinek ilyen hibája kérem ossza meg a megoldást.

Sziasztok!
A fenti gépnek zöld a képe, antenna nélkül lepróbálva. Katódok testre, kék semmi... JVC feliratos samsung cső, A68QFZ893X002
Próbáltam regenerálni, adtam neki 12V-ot, négyszer vagy ötször is végigmentem rajta, de a kék, mérésnél éppenhogy van (100mA), icipicivel mindig jobb, de csak 12V-on, 6V-nál semmi...
Sikerült már valamelyikőtöknek ilyen Slim szemetet rendberakni?
A héten jó lenne túlesnem a gépen, van elég más dolog a házzal kapcsolatban :)
Köszi!
Üdv:
Pityesz
