,,Well I'm struggling here. I've got 42PD5200 with a blown out smd transistor on IC201 - daughterboard of the MPF7409 Power board. I've removed the IC board & tried scanning it at 19200 dpi in order to read the tag on the transistor - no joy other than its a CQ with some other digits that are so small you'd need a microscope to read it..
It's really annoying when everyone says 'check ic201 if changing fused resistors & mosfets' & nobody knows what to do if a fault is present.. so yes,, ic201 is at fault,, yes the smd transistor is blown,, so the question is.. 'WHAT VALUE is the SMD TRANSISTOR ?????'
'CQ' smd is listed as 2sc2411k n npn darlington by Rohn OR MSD710Q Motorola pnp OR 2sc4097 - another npn transistor 32/40v @ 0.5a.. amongst others.. it seems the more you search on 'CQ smd' the more you get..
I've also had suggested that its 2sk3018 which is a 30v 0.1a n channel mosfet based switch.. so now i'm confused..
any experts out there that have a definitive answer,, please let me know.. or if you've got an IC201 or indeed a MPF7409 psu spare,, let me know 'cos im stuck !!
