Hello,
Sorry for asking on Christmas weekend.
I am looking at the main board of a Hisense TV. There is no Led Light with power plugged in and it does not turn on.
Theres 16V and 12V output. The 12V does get 12v when power is plugged in. But the 16V des not get power.
There is a pin labeled "sw" which I assume is switch. It seems as if it may be shorted to ground. As
1. There is continuity between ground and SW
2. There is 12V between SW and 12V pin.
So I have two questions:
1. Should the 16V pin get power with power plugged in or does it need to be turned on?
2. If it needs to be turned on What can I do to turn it on? short sw to 12V, gnd or something else maybe?
3. in your opinion does it seem that sw is shorted to ground?
4. If so what are the things I could check.
Thanks for the help
