Hello friends, I am lost with this rca ultra slim tv rc21t6 I will appreciate your advice and fight for a while and nothing styb voltage well voltage of + b110vdc starts and in a few seconds it turns off it failed to see light on screen if someone can guide me in this repair or provide diagram I will thank you very much

Notice that the closest thing to the chassis number I find is cy-ph2529top ver5.0

Start by measuring the vertical voltages to see if they are well and that is not why you protect yourself
