Hi Turnip,I might be talking out of my hat,but check that the electrolytics in the output for the LEDS,If the set has been laid on its back (panels to bench)the caps break away from PCB very easily,I've done it a couple of times,I think then set goes to st-by.Just a thought.

Hi TV Tony,I know you repair a lot of LG products,just curious,do you change the strips,or replace the LEDS?
tv tony:
Hello,
I change the leds, using a leister hot air gun, you just have to be careful to align the lenses afterwards, 80% success rate 1st time, the amount of leds on each stick are staggered but I use a redundant laptop psu (19v) After splitting the strips. Obviously the sticks with 5 lamps on each stick will be dimmer. They can go s\c or o\c, the hardest part isn't replacing the lights, it's re-aligning the lenses. If you want the address for obtaining the leds I'll dig it out. They come in rolls of 1000 but cost peanuts.
tv tony:
Just seen how much you pay for lamps Bonesy, a thousand for around £18.00, I'll find you the address.

Yes please Tony.To start with I replaced all the strips,not cheap,but 100% no come backs.But I've started replacing LEDs then testing LED strip for brightness & overall even brightness,but the first two I fixed around two months ago by looks of it are coming back,LEDS failed again!Do you replace just the failed LEDS or all the LEDS on the strip?Also what do you use to refix the lens.I've been using a gel type super glue,which seems to work o.k.,some use clear silicon rubber.
