The problem is with this model of TV, namely a black screen with a backlight. There is apparently an altered motherboard, as the sticker on the board shows a different matrix model to the TV. Symptoms are that when switched on, the white LED and backlight come on, but no picture.
The matrix is JE400D3HD1UX/1 and the sticker on the board is LSC400HN02
Please help, regards.
