    Qomo QIT 1055Pro - no image.

    This is 55" interactive touch screen display. The monitor is switched on from the st-by state, the green LED is on, unfortunately there is no picture and no backlight. All the output voltages of the power supplies are correct. Motherboard is described as T.MT5320.A3A 11422. Voltage on the stabilizers U1 3.3V, U2 3.3V, the stabilizer next to U2 1.27V, U4 1.3V, U10 1.54V. I suspect the problem is in flash memory load GD25Q64BSIG. Maybe someone has a working dump and can share? I'm attaching dumps from memory 25Q64 and 24c32.
