Picked this set up cheap today, looks Like maybe a Tcon fault ( what do you think ?)

Tcon looks to be a pain in the ass to source tho

Its still worth taking the voltages of the tcon now with the old chip fitted in my opinion, just incase the new chip is also faulty some ebay chips can be faulty when new.

Try Emos TV. They offer a cost effective repair service of AUO Tcon boards. I had a KDL37V5500 in today with exactly the same Tcon fault. They also guarantee their service not worth trying it yourself. Best of luck to you.
