Samsung PS50B450B1W Y-Sus schematic

[monti]

i just got this Samsung plasma tv and the Y board is butchered by the previous person that worked on it so im looking for a schematic for LJ92-01601A rev. AA2. I tried to find service manual for the tv but all the ones that i found have no schematics in them. If any of you have that schematic or can point me to service manual that have it i will be very thankful

I guess there is none available. So big help will be if someone with a good board can tell me what parts are on Q5001, Q5002, Q5004, Q5005, Q5008, Q5009, Q5010, Q5011, C5066, C5000, C5053, C5065, D5001 since someone played random parts swap

check R5085 / R5086, if there is a short across them you have 1 or more blown buffer ic chips.
Also, what is in the white revision box? AA6 or ?

The buffer ics are fine, rev AA2. there was short on VS to Ground found one of the big transistors shorted and now the short is gone, but since the person before he changed a lot of parts in which process f-up the board i wanted to make sure everything is put back to original
