    Hi to all members. I repair different types of ups, lcds and computers. Recently my friend gave me inverter board of Apc surt 8000xli for repair. The problem is that 3 high watt resistors are missing from inverter board (image attached) due to overheat and pcb burnout. In a youtbe video, 2 red resistors are marked as R1453 and R1454 (couldnt find the num for the white one). Anyone who knows the value of these 3 resistors plz help me.

    Hi.

    I have the same issue. But in my case its not so heavy. The R1444 is the same as R1505 (Ceramic 5W ¿ 100K ? - legend say 5W100KKW.

    The R1453 and R1454 I think are high power wire wound resistors, but I dont know the value.

    Do you repaired de board ? Any one know the value/type of R1453/R1454 for the inverter board 640-0762G REV 07.

    Thanks
