In addition to pq32, you need to measure voltage on components which are connected to pq32. which IC does get hot?

no any hot component connected to pq32

Do you mean PR21 - RL3720WT-R030 which is a current sense resistor.

Check the LCD connector CN1, you should have 3V on pin1,2,3. And check voltage on pin 21 .
