if all 4 inputs work with another input source(i.e. your Motorola box) it indicates the issue is with the TWC input source. Also check your HDMI cable to be sure it is in good condition & properly plugged in on both ends.

Sounds like a power board issue. Unfortunately this is a common problem in flat screen TVs. Typicality this happens after the tv is three years old or older. Some will last several years. The repair is almost cost prohibitive. The replacement board if you sent it out to a repair shop would cost approximately $190.00 and altleast two hours labor $180.00 for the repair. Most repair shops also charge for a diagnostic fee. That fee most likely would be around $50.00.

Those 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.

Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset.

Try opening your menu options and search for "updates" Usually when you set your TV for the first time it usually guides you to do this firmware update. Try acting like your are setting up your TV for the first time and maybe it will have a option for this.
