Does anyone know where I can find the service manual (if it exists)
for the Sharp LC-15SH7U?

When you hit power, the red light comes on for a few seconds and the
unit shuts off. I probed a few labeled power supplies, and it appears
they come on when the button is pressed but are low. The unit failed
during a power outage. The replacement main board is about 200 bucks,
which isn't worth it for a tv like this.

I don't mind paying for the manual, I just can't find it.

Thanks,
Steve
