Default Re: Philips 234e problem

From another service manual it has this description but no schematic:
SM4043, SILICON MITUS, MNT, VDD
BOOST + VGH BOOST + VGL C/P +
VCC BUCK + L/S + OPAMP +
DISCHARGING + GPM + PVCOM, QFN,
R/TP, 48
The manufacturer seems to be Silicon Mitus. I found a datasheet for a SM4028 but it does not have a pinout, so It might be difficult to find one for the SM4043, it might be custom?
