Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I'm Looking for a remote for the Norcent LCD TV model number lt2723? My Norcent will run for 10 minute and turn off so I would have to unplug it to get it back on for another 10 minute is there a sleep timer on this unit? I think that the remote will have that mode.

Hi,
First thing, turn off the TV and unplug it for about 2-3 minutes. Remove also the batteries on your remote. Re-install the batteries on the remote and plug in your TV. Power on your TV using the remote. No luck?
Norcent may not be supported by a universal remote. If you just bought your unit new (maybe Best Buy who carries this brand) you are still covered by its warranty. Below are ways you can reach Norcent.

Had the same problem on my norcent 2722 too. Change your PC resolution to 1280 x 720 pixels and try the inputs again.

We have ten LT-2722 with similar power problems, at beginin the monitor turn on and off after few minutes or hours, then no turns on at all. But the problem is not at the Power Board, is a bad contact or damage in a integrated circuit U403 (GM1501-BD) at the Main Board, unfortunatelly this IC´s pins are unaccessibles so you must replace the all Main Board (Part Number CBPFF84KMGNCT)
Good Luck.
