Need a little help here.
the backlights flicker when watching tv. Everything else works as it should. Also it's not the picture that's flickering just the leds.
I tested the leds and all light up and measure 77.5v volts. I took the tv apart to double check leds and they all work and light up perfectly.
I believe it's the power board causing the issue however I cannot find a replacement board so I'm stuck to finding the bad component. The power board has a sizzling sound coming from the backlight transformer. I replaced that and problem persist. Also replaced the film capacitor next to it and that seemed to help with the sizzling noise but not completely and still flickers a little bit.
All voltages on the led driver board are steady and do not fluctuate.
Looking for some advice on what to troubleshoot next.
Thanks in advance
