Question about Sylvania LC420SS8 LCD TV
This symptom appears when power supply board got problem in tv. It seems power supply board is defective in tv that is why it is not turning On or it wont show power in indicator.
If you are handy with electronics stuff and have prior experience then unplug tv from wall socket, take off back of tv by removing screws at top-bottom and sides and check main fuse located on power supply board, replace it if found blown, replug tv and check.
If fuse blow again then replace power supply board as power part number written on it.
Hope these info will help you.
Let me know if you have additional question.
