Apologies for the double post - I ordered a service remote, which arrived today, and it enabled me to turn the TV on and it (so far) seems to work fine.

Would this imply my issue is indeed a power supply issue, and not (as I feared) a broken panel? I also bought myself a multimeter and plan to check the voltages across all boards. Or am I being too optimistic?

Edit: the TV turned itself off again after about 45 minutes of perfect picture. When I turned it on again I had that half panel issue. See additional photos. [ATTACH=JSON]{"data-align":"none","data-size":"full","title":"IMG_2788.jpg","data-attachmentid":3175694}[/ATTACH]...

Ah that’s a shame - thanks - so you both reckon not worth trying to fix?

Was this issue ever resolved? I have what I think might be the exact same issue...
