TV itself is working fine otherwise. Disconnecting AV board shows the same behavior. Typically LEDs will be turned off in about 10 seconds.
IP board is a BN44-00265A. I found a bad Capacitor and replaced it.
Near that Capacitor is a Transformer: IP-N46-PFC which looks burned but it could have been from the Capacitor nearby.
I measured 13.x V on the primary Side and nearly nothing on the secondary. I suspect I would have to replace it but I am not sure about that. Both coils have next to no resistance (0.001 Ohm).
Trying to find a replacement however gave no results on search engines. Maybe someone has an idea on which transformer could replace it? Sadly I could not find a schematic on BN44-00265A.
I have read about older CCFL pulling more current. That could explain the shutdown of LEDS too... replacing the transformer to me looks more promising at the moment.
