Fuse is located on the power supply board inside the TV.

Be sure that your signal is strong enough coming through the HDMI or coax. If your signal is strong enough, it may actually be your TV's power supply needing to warm up.

Your input cable is in wrong slot...switch around and it should work.

sounds like you have a bad capacitor(s). my TV did the same thing, so I removed the back of the TV and looked at them and noticed (9) of them were bulged at the top ( should look flat). I am no electrician by any means but was able to replace them with a slightly higher voltage myself for around $45 instead of someone servicing it for $400

this happened to me about a week ago. It was my cable box. If you have a cable box,unplug it from the electrical socket Wait about 30 seconds and plug it back in. give the box time to gather all info and then retry the tv.

Check all the input cables. The set has no signal.

Is this a question or what you call your suppy?

Unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This must make it a hard reset. If you wish to do a system reset, you have to enter its service mode to do this.

The main power supply board houses the main fuse. Beware, some sets have multiple fuses on the main board. Besides a fuse, some sets have input filters for incoming power. These filters are before the main fuses, so if you have one, verify that you are getting power out of the filter

Yes it's. Just bring it 2the nearst electronic shop for repair. T power my be spoile or some insect get inside n make it burn. It's ever happen 2 my tv also.

There are numerous conditions such as a bad power supply, sustain boards, or panel itself that can cause your problem. You will need to get a diagnosis to determine the problem.

This is a command fault. The Inverter is the most command reason. flattvparts.co.uk01329 825 403 - Monday to Friday 09:30 - 17:00

Could be the power supply overheating and going into protection mode. If it is under warranty use it. If not then you could take it apart (this will void warranty) and check for swolen or leaking capacitors on the power supply.
