No idea i only just noticed it said for A190406 only on the sheet which mine is not. it installed ok though worried i might have bricked the tv
the only difference i noticed is the sound is now not distorted at very low volumes.
when installed it says it j1017
The freeview tuner is krap though in these tellies i spent 2 days mucking about with the aerial and channels either did not show up or kept disappearing. for some reason it only finds all the channels when doing a FREE CHANNELS search not a all channel search. very weird.
