Question about Sceptre X37sv-Naga 37 in. LCD Television

1 Answer

Power problem Our 2.5 year old Sceptre X37SV-Naga have the similar but different power problem. It will suddenly stop working, but it will come back after we unplugged the power then plugged it back. It can worked fine for another 40 to 80 minutes then it happened again. This started around two months ago, and it went totally dead yesterday. Do you think this is the same problem? Thanks!

    Yes! My TV would last a bit longer, but then click off, with the amber power light still on. I'd unplug it, wait a few seconds for a click, plug it back in and it would turn on. Then one day it didn't. Now I cannot find anyone who will touch it (no fault codes or factory parts lists available, no authorized warranty repair people anywhere). Sceptre says to ship it from PA to CA ($100), pay $250 plus parts, then $100 to ship it back. I'm trying to find out my warranty info from Costco, its been just short of 2 years. I'm now watching my old 27" Trinitron that is 15 years old without a problem...

    I also had the same problem. I was using my Sceptre X37SV-Naga without any problem for 1.5 years, then one day, while I was at work, it went dead. I suggested that my wife unplug it for 30 seconds, then plug it back in, which worked. For a few weeks, this would take care of the issue, but every time, it seemed to take longer, or more tries. Now, it won't power on at all. I had a friend that works designing power supplies test out the circuits, and he found that the two thermistors were bad, as well as a boosting FET. We replaced the thermistors, and now the green light comes on, but the power button does nothing. I'm assuming the power supply isn't getting enough boost to turn on, so the FET seems to be the issue now. I'll replace it and see what happens. Also, my friend suggested replacing the two thermistors with a single 5 ohm unit to increase stability.

    Came home to find the tv had no power. I have had it for about 1.5 years. Sounds like Sceptre drop the ball on this one. Funny how it seems to go bad soon after warranty. Class action lawsuit needed.

    After my posting in July 2008, I did contact Costco. They got hold of a guy from Boscov's who came out, verified the powersupply was bad (but insisted there wasn't a thermistor problem). Anyway, Costco provided him a way of ordering the powersupply from Sceptre and he replace it and the set runs fine again. I still have a lingering dark shadow (sort of looks like Mt Rushmore faces in the background) and when the guy put the TV back together, he put some long screws in the short screw spots which made some bulges in my plastic, but I don't really notice it. He insisted there's only a couple of brand name Widescreen LCD manufacturers that produce anything that will last more than 3 years, all these no-name TVs are just expensive throw-aways.

    Shoot! Sounds like I have a similar problem. TV's about the same age. A month and a half ago, it suddenly went off. We juggled the set around a little to see if any power cords had come loose or possibly the outlet blew. Nothing found. Then, turned it on and it mysteriously worked.

    Now it's off and we can't turn it on. Slamming the set with a flat hand on its right side seemed to make it power on but it wouldn't stay on. Now, banging on the set seems to start the "green" light glowing weakly, then it goes away. Can't get the red "off" light to glow at all.

    Anybody have some ideas? Where can I get this fixed? (I live in San Jose area.)

    Shoot! I have a similar problem and TV's about the same age. A couple months ago, the set wouldn't power on. We juggled the set around, looking for loose power cords or a possible blown outlet. Nothing. Then we pushed the "on" button again and it mysteriously came on and worked.

    Now, we can't power it on at all. The red "off" light is never on. Banging the set with a flat hand starts the green light glowing weakly then it peters out. Banging was effective maybe a few times -- now, even that won't work.

    Any help? Where can I get this fixed? (I live in the San Jose, CA area.)

    We also have been having a sim ilar problem with out TV. The power supply seems to just stop working. After we unplug the tv for a while it will continue to work for a little while. Today we encountered a different problem... now the picture completely goes out while we are watching, and nothing has helped... even unplugging it.

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.

Where can I get a Audio/Video cable and Power Cord for my Sceptre 30' LCD TV-X30SV-NAGA III?

They should be fairly generic and most major electronics stores should have them.

On the internet in North America look at MCM or Suburban Electronics as both carry a lot of these items.

My SCEPTRE X37 is making a distortion noise when turned on the volume works but not with out a humming sound ?

Wondering how old the set is?
Is it still under warranty - if it is - take it in right away and get it fixed.
If not - my thoughts is that you are going to have a problem with the power supply soon. This usually is an indication that something 'not good' is happening to either your main power supply or the Florescent back lamps ballast power supply. My thoughts are bad Capacitors that are drying out. This happens on many of these types of LDC flat panels.

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.

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.
