I inadvertently threw away the base / stand for my Emerson LF391EM4-A television. Any idea how I can get replacements? Apparently it's a two-piece base stand.

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.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Here's where you can download the owner's manual, if you'd like to science your way through such a replacement. Walmart Emerson LF391EM4 39 1080p 60Hz Class LED HDTV

Unfortunately, cheaper TVs are meant to be sort of disposable, as most would just want to buy a new V than to fix it themselves. It may be glued together and you may have to break some seals and some warranties doing this yourself.

Good luck!

You will need to replace the battery on the input board,similar to the bios battery in a computer

Depends on where you get your service. Where I liveon East Coast of US, ya got to have a Comcast box (DTA Digital Transit Adapter) or better) PERIOD. Currently, there are no TV sold in my area that can beat the Comcast system. It may be different where you live.
