Philips Roku TV not powering on
Philips Roku TV went to green distorted pic then powered off now will not power on
If it's still under warranty, contact Philips. If not, well you're probably on your own. If it won't turn on there's no way to reset it and it probably has a fairly significant hardware failure.
