SOURCE: I have a sylvania lcd tv that only stays on 1-2

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Does this set have a digital tuner?


This model does not, it requires a digital receiver. Unless it is being offered very inexpensively, it is not a recommended purchase. Thanks for using Fixya.com:)
