First try checking the "auto off" function. I am not familiar with Akai TVs so this advice is very basic. Use the 'Menu' button and find Settings, (It might also be listed as Set Up). Go into this section of the settings. There should be a feature listed as 'Time' or 'Timer'. Set this to Off. Your other option, if it is a brand new TV is to contact the store you bought it from and ask their advice.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here.
