    Panel Heater Power Board repair

    I like desoldered and soldered back 10 times already, when there is 1k resistor attached on the end, it outputs 12V...

    So, I replaced 2k resistor with 1k resistor, and now its outputting 12.3V...

    The green one is 22uF i tried replacing them with 22nK100, but that didn't solved anything

    The two caps before the PN8024R are each 8.63uF(I guess this is together since they are connected in circuit), in circuit, for reading off the circuit, there is a table above I already sent

    This outputs 15V... instead of 4.7uF/25V i put 10uF/50V because I dont have 4.7/25V, and instead capacitor 333, i put 2A223J green capacitor

    When I have control board connected, it burns AMS117 3.3V... and contorl board beeps repeadetly fast, but when i check after AMS117 its shorted... i replaced it a couple of times.. Control board works fine on 9V battery when connected(and AMS117 is new)...

    Yes, I have desoldered all components, and checked them, here is the list. @bertus Yes,I have checked it, I am not building their rtypical usage scenario with these components to see how it will behave.
