Question about Sceptre X37sv-Naga 37 in. LCD Television
The TV is plugged in and on, then it just shuts off. The power light stays green, but no picture or sound. (power light is red when power is off) I sometimes notice the power light is green even when I have not turned the TV on. If it is, the TV will not turn on. I've discovered that unplugging the TV for several minutes, then plugging it back in remedies the problem. What is wrong??
The power supply board is defective.The board where the power a/c cord plug into it.That ur power supply board.Replaced the power supply board,ur tv power will return to normal and work as bofore.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Look for poor solder joint in the power supply board, its the inrush current limiter Thermistor (SCK-85, round disc ) clean both legs real well before resoldering, very common in this TV. Clean the legs and the PCB real well you may to scrape off some of the Green PCB coting to expose copper underneath, then bend both legs flat with the PCB to get more contact and soldering areas, this parts gets hot and cold (thermo cycling) when you turn TV on and OFF, so the soldering works must be really well done.
