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. http://electronicshelponline.blogspot.com/

The thread size is standard, just a metric standard. To attach the Sylvania LCD427SSX to the wall mount bracket you'll need (4) metric 8mm machine screws with a 1.25mm pitch. You'll find them at your favorite neighborhood hardware store with the designation M8 1.25x40mm. (40mm long...the 30mm would be to short)

In my area, Comcast has blocked all free watchable basic channels. You now need a very small but special box to receive those. If it's a conventional cable box, you might have to call them to send a signal to reset it.
