My Sceptre T.V. starts to flicker then it turns completly off!!! :(

If it is fitted with a rewireable plug check the tension of the contact screws.
If the plug is non rewireable I would suggest there maybe a break in the wire somewhere

That could be a T-Con board failure. If you can change channels, turn up the volume etc, then it could be the T-Con.

it may be from inventor board that make light for screen.

The Sceptre is a fine TV but is very sensitive to power surges.
If the unit turns off, soon after powering on, it is most likely the power supply.
Try disconnecting the power to the unit for 20 minutes and allow to completely cool down.

Re-connect the power and try the unit.

Hope it works for you

Look for bad caps like the 17" version here:

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Please post back what you find.

1. check power supply
2. check flyback

Ether or you have a ppower fauilure in the unit. and its probably blowing fuses.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

Probably the inverter board of your monitor has been exhausted. The inverter is the part that enables the monitor to glow, making a little fluorescent gas lamp insithe the LCD bright strong enough to illuminate all the panel. When this circuit has some disfunction the lamp could oscilate, ficker and finally die making the panel dark and you couldn read what's on the screen.

The inverter has a lifetime, and the lamp too, check the lamp lifetime of your monitor and the inverter too.

But this could only be performed to a qualified person, due the high probability of electric shock if you try to make yoursel the repair.

Good luck

I had the exact same issue. I bought a new tv for my family room and moved the Sceptre to a seldom used location. When I did turn the Sceptre on after a couple of months, it was good as new. The dark areas disappeared completely

Check some of the other posts as it is probably just a bad capacitor or two and very easy to fix if you can do that sort of thing. I did and mine is back up and running.
