Report "Does not turn on, no green power light. Previously, had the brightness menu popup on screen a couple of times, couldn't figure out why ! I've now got the power supply panel out but can't see any visual problem signs (burnt out components etc). I took out power transistor K3530 and tested with multimeter but not sure of results. From center leg to left hand side leg have reading in one direction only (which i think is ok) but have open circuit on the other leg. What do you think ?"
