tv magic queen 21MQUSF9 chassis 40-00NX56-MAR1XG. turns off
when it turns on it has an image on the screen ... it has sound ... it follows the sound when the screen is turned off ...
Good afternoon, nicomena. Thanks for answering. If it has image and audio, but when it is turned off, not anymore, and logically because it is even turning off the source, the b + drops to 24 vdc and the other secondary voltages also fall
A while ago I was watching an earlier post, and following the steps that indicate there, I already got the Q802 in short, I will change it and I will tell you, ah! and R816A is overheated. I'm going to change it too
good morning friend nicomena. I commented that I have already solved the fault. It was caused by Q802 = 2n5551. It was short, it is located near the flyback. and is fed from the b + line through R814 and D814. The voltage dropped to 24vdc because the source was protected and when it was turned off it was in stamby, and this chassis in stamby sends 24 vdc.
Thank you for showing interest in my case.
