Hi this oldie had no backlight .after replacing caps on 24v rail ,
still no b/l this uses inverter type:1315 B1-16A,
im sure ive come across the same inverter in a samsung possibly le32r88bd ?
all t/x in board test ok ,so i fitted 15k and led to pin 4 of oz964gn ic
this allows protect to be temporary overridden.
b/l now comes on
but the left hand side of pic is gradually darker than the right side
i have the cct for the tv
but it does not have inverter cct.
i opened it up to inspect the ccfl tubes
and they dont have any black marks at the end
and the light produced is the same gradual light to dark,
in the past ive had individual ccfl s fail
but never had this shading effect
i suspect something on the earthy end of the ccfl s ,
possibly a component on the inverter board
can anyone help with a cct
