HP1740 not working correctly, problem with colours and flickering

Most likely the problem is with RTD2523.

The board is BENQ 48.L1G01.A02.

The power supply is providing 4.97V and 3.28V in standby mode and 4.93 and 3.26V in "on" mode.

I checked and the chip should work with voltage greater than 3V, so 3.26V should be fine.

Now I have RTD2523, will write later what happened.
