How can I get a universal remote to work with it?

Select a universal remote control at random and use its code search (or equivalent) feature to find something that will handle some or all functions of your Emerson TV. If a search through all codes stored in the remote fails, you may have to try a different universal remote. All universal remotes do not store all possible codes.

Do you have the correct cable connected to it? If you don't have HDMI or DVI, the TV will sense that and not switch over to full HD. There may also be a setting in the video settings menu that needs to be adjusted. Otherwise, it should be automatic.

Wheres the regulator board

The main power board is called the regulator board. It can be located by following the main AC input wire, by which it will go directly to this board after the main on/off switch.
If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.
