Re: diagnosing sony XBR-75X900H. NO PICTURE
I swapped the t-con and main board today to see if that would resolve. Now I’m getting no backlight so I will probably swap back and diagnose since I don’t believe that was the issue. I checked the fuse on the t-con board and it’s good. I will take off power board and inspect on the morning but I don’t see any visible damage. I’m really hoping it’s not a bad panel but I don’t even know how to diagnose that besides ruling out everything else. I get 4 red blinks now and nothing turns on.

Re: diagnosing sony XBR-75X900H. NO PICTURE
I tried lookin in the sticky threads. I have no idea what I’m doing but I have a muiltimeter and I am a fast learner. Can someone point me to a write up of what to test?
