You're going to need to open up the tv and do some resoldering of some components. If you don't want to do the soldering find someone who can. Or if all else fails I'll take it off your hands just let me know.

I have a Gateway Plasma TV, model GTW-P46M103. I am not getting a picture or sound.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

GTW-P42M203 shut off and will not stay on

Chances are there are cracked solder on one of the boards. This is a common problem with Gateways. If you're handy with soldering then this is an easy fix.

Lightning damage to motherboard in GTW-P46M103

If the insurance already paid you for it and this could be a 2nd TV for you if you repair it then my opinion would be that it is worth having someone come look at it and give you an estimate for the repair. Call and find out if they give free estimates or what it would cost to come to the home. Most likely the whole repair is going to be around the $500 anyway but its cheaper than buying another one. If you can't afford it then if you bought the same model keep it for parts on the new one. Hope this helps and ask more if you need to.

I actually bought the 5 year warranty when we purchased this new and it was still under warranty. Gateway is sending us a brand new TV. No need for me to try to fix this, but thanks to all involved.

Mine does the same thing. Was told by the TV repair guy it is a bad control panel.

Plasma tv GTW-P42M102

Sorry to tell you a common problem with these sets. It is a bad capacitor in the main power supply.. There are really about three of them that go bad from time to time to cause this problem... If your not a tech you should find an authorized repair facility as a non authorized is not going to know what to do to fix it and it will most likly cost you double to repair. Good luck and let us know how you got it fixed.
