It is equipped with the FSQ510, L6599, FAN7621B and R2A20117 ( PFC integrated circuit ) and are in a PHILIPS 52PFL8605 K/02 led TV chassis Q551.1E LA. The front light flickers 3 times, the voltages of 12 and 24V are missing (PFC does not work), thank you in advance!
I changed R2A20117 without success...
