LED TV at home seems to be not turning ON(sometimes after a long time after power on). Opened it up troubleshooted the issue to power board section on the TV. No output voltage from the board to the Panel or the processing section. Input AC section seems to OK. No visible blown parts on board either. Trying to debug the root cause of the issue on the power board. Maybe a shorted cap or a faulty MOSFET? Still no idea. Debugging unknown circuits is fun. 😀
Even if you are not able to fix it, you will learn a lot.
