No special tools. Take off the back, and you will see the matching board you have. Make sure unit is unpluged.

There are two possibilities for this fault. The first one is with it deflection yoke connection. If this connection have any loose contact at main board side, horizontal sweep pulses will be absent to deflection yoke. Check this plug in connection first. If it is OK, check and replace the CRT connection socket.

LCD TV Remote quit working

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.
