Hello I am new to the site, I have an Hisense LED 32K20DW TV that was given to me and I have tried to power on the unit and the stby LED will blink 6 times, return to a steady state then turn off, I have not opened the case yet as I was not too sure where to start, I can check the supply voltages printed on the PCB as they state, but if possible could someone help guide me where to start? Thanks
