Its from Walmart. I don't expect a nice long lasting TV..pass.
It has nothing to do with WM. Rather, for cheaper, more affordable HDTVs, manufacturers will intentionally make inferior tabs (those electrical tapes that connect the LCD panel to the electric connectors coming from the PCB boards) which will fail right on the dot after the default MFR warranty period expires.
So what's my point? Make sure you buy/get one of those Squaretrade extended policy for these cheap LCDs.
