Title: Aging mode continues until power is off
Post by: P.R.Gore on August 11, 2021,03:25:09

Hi
55" tv with 4K combo board TP.HV553.PC821 with hiSilicon micom & Samsung display panel LSC550FN011
is continually displaying aging mode patterns. There is no OSD so service mode not possible. Print log shows "AgingMode AS system"  Panel ok on other testing board.
Can someone guide to recover from this problem?
Thanks.

This is getting all too common on these elcheapo TVs. The patterns are sometimes generated on the T-Con, sometimes on the combo board. A first possible step could be to remove all inputs to the T-Con and supply it with 12V at the T-con fuse. If the patterns persist, then it's the T-Con likely at fault. If they vanish, then the main board is likely and replacement is invariably the only way to go.                          Bruce
