Good afternoon, mates. I have a DVD Home Theather brand RCA Model HT917DA which is dead. does not turn on, at the first check no damaged component is noted, check input voltages and they exist, but there is no output voltage. there is no voltage at the input of the choper transformer, before this is an IC PWM with registration DM0565R but it is not clear to me how to check if it is in good condition or not and try to get it but there is not. I hope you can guide me. Thank you for your opinions.

I sent you integrated information. Check if voltage arrives at pins 1 and 3 If you check the other elements and they are fine, it would be best to try another new IC and also change the optocoupler On page 14 there is a typical circuit with this integrated FSDM0565R

Effectively the problem was the IC, it was replaced and it was already lit, although it presents other problems that later arise. Thank you.

Good evening. I have taken again the values of the voltages and what I got was: Input capacitor: 158 V. Pin 1 of the IC DM0565R: when placing the tips 1, when removing the value varies (will be giving me infinite? Pin 3 of the IC DM0565R: 11.15 V. Optocoupler input: 0 V. At the entrance of the Choper Transformer I have: Pins from left to right: o o o o 0 V. 0 V. 1 158 V. (those of the input capacitor) Am I doing it right? Will the IC be damaged? Thank you for your assistance.
