Hello Kuro experts, would much appreciate a little help here..
Heartbreakingly my KRP-500A has developed a couple of issues:
1. one intermittently sticking pixel, it goes 100% green, most often when it's trying to display shades of grey: I'm hoping this can be fixed by adjusting voltages.
2. after an hour or so, alternating red/blue squares on the main panel (service menu says that's: "communication between the MR and the display cannot be established for any reason") or panel goes black and flashing blue power LED - I guess it's overheating, as the longer I leave it off to cool down the longer it lasts until the issue comes back.
I can see the info I need is probably in this thread, but would help a lot if someone in the know could give me some pointers so I don't make things worse, particularly for the stuck pixel.
I have a feeling a reset isn't necessarily what I need - black levels are probably elevated since stock but still ok for me, way better than any LCD, and no red tint at all.
I have a USB to serial cable, but haven't tried talking to the TV with it, in any case a LAN connection may be easier, also unsure if the service menu / KuroControl vs trimming POTs is the way forward on this one.
Also haven't checked if the internal fans are working and/or blocked with dust, thought best to check here before doing things I might regret.
Thanks a lot.
