TV does not show as sign that it has power will not turn on

Your TV needs servicing, Most likely you have a power supply related issue. Do you have any experience with electronics repair?

When the tv is set to av1, it means the tuner is not being used, press the input/source button on the remote or tv itself. it should work fine.

There's something wrong in the power source of the tv , very bad sign on a tv just 2 weeks old. Just take it back, not worth the hassle.

More than likely it's activating the protection circuitry. Most of the time televisions won't give you a sign of trouble until something actually breaks. One day they work and the next they might not. There could be a problem in the power supply or the scan section which are both internal that would inhibit operation to prevent your set from overheating and causing a problem external to the TV like a fire. If your set is over 10 years old, replace it. If it's quite new but out of warranty then get an estimate at a reliable electronics repair store.

Sounds like a bad ignition switch or a wiring problem by the switch.

Most likely the power supply. The part number is 270530 and cost around $130. You would need a volt meter to test.

Press the menu button for 10 sec on the set

The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.
