Repair done this morning. Didn't fix the ghosting. Disappointed that Hisense USA did not provide any instructions for this scenario. Since it is a motion issue the tech could not take a full screen picture which is the normal requirement for panel destruction. He was advised by his contact for Hisense repairs (outsourced) to call Hisense support. Tier 1 did not have any instructions beyond take a picture and update the case notes. We could not speak to Tier 2, which required a call back and tech could not wait around for that to happen. So after Tier 1 took ownership for the follow-up the tech closed up the TV and left.
BTW, tech was very professional and knowledgable small business owner. Don't know how he will be making money in all this. Normal repair is a quick 30m swap parts, fix or no fix, done. He might have to come out again to do "more repairs" or destroy the panel.
I've wasted time unmounting the TV, bring it down to the garage, preparing material to check the problem, time spent on the repair and now have to do the reverse and potentially more pain again. That's on top of the time I spent following up with Tier 2 to make sure I had the right parts. Well at least I have pictures of the whole thing. They ended up swapping the mainboard, TCON board and LVDS cables. TCON has a serial number, so they could check if it is the right part or not. Might update later, just exhausting and I have to get back to work.
