I heard from a saleman at HHGregg that Seiki uses Samsung parts. And for anyone who can't get their Comcast or Direct TV remote to learn the Seiki code... try using a Samsung code. It worked for me, I used code 10178!
use magnavox code 1053
Waths the remote code for pixel
Try 11381
try code 1071. It worked for a sharp aquos 60" tv.
Try 2338...worked for me
1343 is the Visio code.
Try the codes for Emmerson. 1468 worked for me.
I just used a Zenith code 1255 for my Toshiba HDTV and it worked! Good Luck!
I would definitely say that you should check out Rick's coupons picks. You will find a very generous att uverse coupon code there: http://www.rickscouponpicks.com/att-uverse-coupon-code/
For AT&T U-verse on my Hisense H32V77C, I found code 1004 to work. I actually just started trying numbers at code 1000, and got lucky. Good luck!
For the SE241TS I used the LG TV in the "Most Popular" list and the on, off, volume, mute worked. For the "Source" button I used the "Learned" function on the remote using the Input-Pair button, the Page Up and Page Down, and the Select buttons. Using the Seiki choice in the alpha list did not work for me.
