Question about Sony KP-46WT520 46" Rear Projection HDTV-Ready Television
9 blinks is a ZCD error code (zero crossing detection)
which means it is a bad g board. I had the same problem with this tv and have yet to fix it cause you cant find the board you need anywhere and most suppliers have boards that they fix themselves which only work for a month or 2 and then die. but you need to replace Replace D6301 on "G" board and d6116, d6117 i use 1n4148 for the little smt diodes, d6301 nte116 should suffice
it will be those few diodes and 15-20 caps on the am board if you choose to fix it yourself. here is a manual that lays everything out for you if you choose to fix it yourself. click here for repair manual
if you need further assistance please let me know and i will be glad to assist you from there. thanks and good luck
