Need Diode part numbers for Philips Y-Main board. I have a Phillips 42PF320A/37 Plasma TV (Chassis

Question

I have a Phillips 42PF320A/37 Plasma TV (Chassis # BP2.3U) with red flicker, (see http://www.fixya.com/support/t246142-red_noise_or_flicker_bottom_half_plasma) and thanks to Premtech I've located two defected SMD diodes on the Y-Main Board. The reference designations are D5001 & D0018 and I'm unable to determine either Philips or commercial part numbers for these. They both have the marking F4 over 5J. The board is a Samsung PCB Code LJ41-02759A and Service Manual states that for Service it is a "Black Box" suggesting it's not repairable at component level and calls for board swap. I'd like to try and repair it. Also, if someone the board schematic it would help me fault isolate associated circuity.
