its still a work in progress
i have reduced the backlight current ,by increasing the fet source pin resistance
.it had 5 resistors in parallel .47 ohm
i simply removed two of these as an experiment .now the tv b/l come on as normal
i was given the tv so its fine to experiment...

toshiba 65ul2163 dbl no backlights NOT BACKLIGHTS?
Hi this vestel 65in tv had classic no backlights ,so nothing new there!
tested with b/l tester and the b/l seemed to be fine
so investigated psu 17ips72 (on this 65inch there are 3 fets and control iv type DB83630P)
did a thorough check on b/l circuit all ok .
When i tried again with b/l tester all ok .but then when i reinstalled psu all worked fine ,
could there be a component on psu that is causing the protection mode to stop b/l
.maybee causing it to be too sensitive?
it seems to me if the b/l have been on with my tester ,within a couple of minutes... -

just a quick question do all qled leds appear blue when fault finding ?
i have replaced many leds strips that have changed blue when they are worn
and the new replacements are perfect white
but when fault finding do quantum leds always look blue? -
Hi there i have same problem with no hdmi signals on lg 47ld450za
(via aerial all ok )
i have read your post with interest and would like to ask :
did you use the customer supplied remote to enter the option codes?
or did you have to buy a LGservice remote?
i have tried to enter service mode with press and hold ok on both tv and remote at the same time ,but no luck
once you were in service mode can you please explain how to enter the option codes
i have the service manual but its not clear how to enter service mode
thanks -
