Question about Sceptre X37sv-Naga 37 in. LCD Television

1 Answer

Green light on when plugged in

I have my x37sv-Naga for about 6 weeks got it on eBay "LIKE NEW". A few weeks ago when I got the correct remote I noticed that after turning it off (goes to red light) I could not turn it on again. Had to unplug and re-plug 20-30 times before I got the red light. The last few days no matter how many times I unplug and re-plug or how long I wait (some times hours) before plugging in again it always has a green light when I plug it in and does not respond to any of the buttons. Any ideas?

Sceptre X37sv-Naga powers on no picture

Do you get sound? If you do, then the problem will be in the backlight inverter board. You should have 24vdc presents on the main power supply which supplys the power to the inverter board. Please verify that is the case.

I have a 37" inch lcd sceptre. I got in March, It was working absolutely fine just two days ago. Then I moved it to another room (very carefully) and when i plugged it in, the green light came on but no...

Look for bad solder joints of the NTC Thermister in the main power supply board, it will be closed to where the power cord connection is on the circuit board, you will have to look at the bottom side of th PCB. oNLY

Power problem

Check out ebay for the part.

My 3 year Sceptre 27" died. Local TV tech said it was the power module. Charged $25 for the diagnosis and wanted $190 to fix it. Took it home, popped the screws and the module almost fell out. It's a simple plug'n'play!!! Found a new module on eBay for $65 shipping included.

Reply to scb8g from Frank Reed. The only real solution that I would suggest is for Sceptre to recall the power supply and repair/replace them with correctly sized thermistors. I don't there's much of a chance of the TV catching fire because the pcb-thermistor connection opens when overheating occurs so at best, the problem will continue to occur periodically and at worst, there would be a remote chance of a fire. Neither choices are good. I'll write Consumer's Reports this week and refer them to this site. Perhaps they can lean on Sceptre hard enough to get some action from them. Good luck, Frank Reed

Scepter X37sv-Naga LCD

The Sceptre TV do use the Sony codes. However, the cheap universal remotes do not have the buttons needed. The Volume Up/down and channel up/down are controlled with the circle of buttons (arrows) in the middle of the remote.
You can get an OEM remote from Sceptre. They still have them available. Sceptre is in California.

Replacing Sceptre Power supply

The attached pictures are the back of our TV which is a Sceptre X30SV NAGA III. In ours the power supply is inside the vertical panel on the back right of the TV. The plug goes in the bottom of the panel and you remove the panel with the horizontal louvers with 4 screws to get at the power supply. A replacement power supply is from Delta Electronics part number ADP 180CB B , 24 Volts 7.5 amps 180 Watts that we reordered from here:
