Title: power supply + driver LED PLDJ-P978A= PCB P/N 3PAGC10029A-R
Post by: ANDRASONI on May 11, 2018,05:46:13

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...

Thank you, but It can be updated if the TV does not start at all? At some brands , it goes
(Vestel for example), but I do not know if it is also true for Philips.
