Check and replace its main digital board. There should be any shorted component/s on it. This board is not repairable. Only card base replacement can be done. Contact a service technician.

The problem is most likely the fuse connected to the power wires. You have to take apart the TV and follow the power wire to the fuse. Fuse number is T4AL/ 250v. It will be labeled above the fuse. We had the same problem. Also, check to see if the metal around the tops and bottoms of fuse are loose.
The way we fixed it was to wrap aluminum foil around the fuse and put it back in. It is only a temporary fix until we can get a fuse. Hope this helps.

Sounds like the component cables are misplaced. Check that, and report back.

There should be some short circuit to any of its circuit board. Check the main digital board, in this case, as the set switches ON. The power board should be OK.

You can buy an assortment of universal support bracket or universal stands at stores like walmart, Best Buy etc.... Check the back of your insignia and you will see the threaded holes made for this kind of bracket. I bought a 42 inch flat screen and bought a combination table/mounting bracket. It's great. Make sure you get a bracket that matches or exceeds the weight of the TV though. Good luck and feed back if u can.

replace the mainboard.

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.

If under warranty contact the manufacturer ringing the number on the user manual.

I would start with checking the power supply for leaky capacitors

Sounds like the TV is shot.I always find it tough to pick a new TV with all the different technologies out there. Vizio seems to be a pretty good brand in my opinion. There not real costly but you get a lot of tv for your buck. I actually just got 3 of them to replace the TVs around my house. Remember to always check reviews on tvs at places like www.tvrevs.com and see what others have experienced with the TV your looking to get. Just my opinion.

Rule out the tv tuner first by seeing what it looks like when using a rear audio and video input and if using a box check it and the connections for loose connections.

Check this link for details.

Poer supply issue. You can get the replacement power supply from www.tvcircuitboards.com

The standby part of this set's power supply provides voltage 7-24 for the remote to work via the microprocessor and also will provide voltage for the mechanical relay if there to fire the main power supply.
