why won't my TV stay on?

I have a Sanyo TV that when I switch it on, it starts to turn on then immediately turns itself off. How can I fix this? What can be wrong?

Could be an open Circuit! Low costs if a technician re sauders it.

Try unpluggin it for like 15 min - 30 min, then plug it back in and see if it will turn on. This I was told will reset the coputer inside.

Televisions usually have over-voltage and over-current protection circuits, which will shut the set down in the event of a fault. You need to call out an engineer.
