Question about Orion Televison & Video
If there is no power at all, then it is either the power cord or power board inside the TV.
If after the fault the TV went in standby and does not wake up, then the TV is in protect mode.
In protect mode higher voltages from PSU gets shut down and TV remains in standby.(see also Why my TV does not start up and remains in...).
The tip was written for projection TV, but basic troubleshooting is the same on your Orion LCD (disconnect to allow PSU capacitors discharge, and test different devices and cables)
As you can read in the article, the basic troubleshooting consists in leaving the TV power cord unplugged for some times, let say one hour or so. Then connect power back with no device connected.
If that does not work, and you keep having the TV in protect mode, that means that there is a fault.
In that case call the support number listed on the TV user manual to arrange repair.
If you are a technician repair is done testing voltages from PSU, diagnostic points and voltages on main controller board, and DC in and high voltage out on inverter. Here a summary description: How to test an LCD TV .
Faults that may affect an LCD TV after power surges etc (problems that can raise if TV stays connected for long time while on holidays) are inverter, PSU board, main controller board. PSU is most common.
