It is a Scepter X32BV-Naga #718D3NP1AA0318
For a few months now after turning on the television it was taking longer and longer for it to "boot up". (sorry, don't know how else to put it) It got to the point where it would take upwards of thirty minutes. As of yesterday it simply does not happen at all. I plan on buying a new televion anyway, but I wouldn't mind being able to fix this one as well if the cost is reasonable.
Have you tried a "factory reset"
