Refer to the manual (free download
here). Generally, a blue screen indicates a very low or non-existent signal. This can happen when the antenna is unable to gather enough of a signal from a particular broadcaster, or if an A/V input is selected, but the A/V device is not on or providing a signal. Since you are not seeing channel information when tuning, I suspect that the television is set to display an A/V input instead of the internal tuner.
With a working remote, locate the
TV/AV button on the lower left (manual page 3 - item 8). When this button is pressed, you can choose to display signals on the ANT, VIDEO1, VIDEO2 or COMPONENT jacks. The ANT selection chooses the input on the RF jack such as an antenna or cable TV (with or without converter box). If using a cable box, the TV tuner should be set to Ch3 or Ch4 as determined by your cable box. Otherwise, select the VIDEO1, VIDEO2 or COMPONENT input that has the source signals you wish to watch from a cable box, DVD player, etc. that is connected to the rear input jacks. Page 7 of the manual details the connection and remote operation.
I hope this helps!
