Sceptre 24 tv turns on then shuts off after 30 seconds to 1 minute. When it turns on all channels look great but it won't stay on.

Hi,

Please unplug the tv for 30 seconds before powering on the tv again. Also, please check that the "auto power off" features isn't on (Settings >> General >> Eco Solution >> Auto Power Off >> Select Off)

Thank you.

Tuner fault. Check and repalce it. Contact any service technician. Gopakumar Gopalan Google

Try changing the input device to something you are sure, works such as a DVD player. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

It's likely that the TV will require service since your troubleshooting steps didn't resolve the problem. If your TV is smaller than 30", you may carry it in to the retailer of purchase for repairs. Otherwise, service for your TV can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

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

ok this is what you do folks.... un-plug the tv from the power supply. once that is done hold the power button down on the side of the television for 30 seconds. this will release all electricity out of the tv.... then before you plug it back in hold the channel down vol up button along with the power button at the side on the tv this should reset the tv and it will start up automatically on video one. Select your source and scan for your cable channels again. If the problem is not solved then contact someone to come and clean the filter for the tv because it may be clogged along with this it can be the color wheel and may shut itself off like 3 times until it feels it is right.

check your sleep timer settings. they stay on no matter how much you turn your unit on and off.
