Looking for SMD resistor values

[Safrilhg]

Hey everyone, this time the question is very complicated, hope there is an experienced technician.

The BenQ g922hdal monitor experienced a short in one of the SMD resistors in the power section.



From the picture I attached, the path leads to the SMD capacitor and to the leg of the LD7560GS IC.



Can anyone help determine the value of the SMD resistor?

Thanks for help, But according to your guess, what value is suitable for the resistor. If I 220 ohm.

The service manual and ic data, the cs pin does have a cap and a 220 ohm resistor i would try it if this was a repair i was doing .

Yeah, iam gonna tested, if the components burn, that's so amazing hahaha.

can you use a dim bulb tester too see if you still have a short when powering on saves blowing new parts etc

I will do a physical check on the PCB, but I can confirm that the short circuit occurred due to corrosion.

And will check the path with a multitester.
