ILO - Do Not Buy
These TV's are horrible. It isn't worth the little bit of money you save.
The first thing was that most universal remotes or cable remotes won't work with it, unless you have some expensive remote like a Logitech Harmony.
The second thing that happens is the power supplies go, so then the TV's power light will flicker and there is no picture. So then it's just a big paperweight.
Third, try to get someone from ILO on the phone. Let me know how that works out for you.
If you want some examples, just do a search with the words ILO and broken and see what you get.
WalMart probably keeps them around because they last more than 90 days and after that it's the manufacturer that hears about it. So they probably aren't getting the feedback. Who knows maybe by now they've stopped carrying them.
