mitsubishi wt46805 projection tv keeps blowing pico fuse

pico fuse 5a location f9a23 keeps blowing

 

i have installed 4 different sets of stks (due to convergence not working at all stk chips cold) and pico fuse keeps blowing.....so i know its not bad stks since i have tried 4 difirent sets

 

if i pull stk out and turn tv on the pico does not blow

 

from what i understand this pico powers the stks 

 

i have been troubleshooting this for weeks can anyone help me
