Just on these logics (T-con), samsung has been using FutureElectronics products for some time (a sub-brand of known Mouser)
Link_ channel P The low output * 19pF-25pF is important for this P-ch transistor
Field PCs for 3A / 20-30V current described on the housing as (58 ? 3).
As a field with N-chanel uses ZXMN6A07FTA, in DC-DC converter circuits.
(7N6 inscription on the housing).
This applies to T-con (eg T-con S100FAPC2LVO.3) for matrices from the series (LTF400HM0x) x = 3 / or 5 using SM4109 (
on which there is no datasheet "u. )
Apparently working at f = 650-700kHz ?!
Apparently a "light copy" of MAX17122, which was used in LTF400HM01 (T-con F60MB4C2LV0.6), see appendix.
ps
Usually the problem lies in the matrix, broken connections in the glass of these matrices (drivers integrated in the glass) (look carefully), three tapes on the left and right ... or the slow "agony of the matrix" begins. That's what it looks like.
