SOURCE: norcent not working

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.

Hi


Thanks for using FixYa. From what you have described it seems the issue is with the power board or the main board we’ll need to check few things. When you open the unit up; take a look at the power board-the board where, the power cords/plugs goes into. You might see some filter capacitors a little bulged up in the top-If this is the case-this is your defective part(you can try to replace them-but some soldering equipment is needed). If not, then probably the main board has gone bad. This is the other board-where all the inputs are going into. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.
Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

Norcent tv model lt2722


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.

LCD TV Remote quit working


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.
