Television and Home Theater

Help! poor blonde female having trouble sorting out a portable t.v. I've been given.  It has no remote control or instructions (although I have a 'One for all remote control' - however no instructions for that either!)  cAn anyone help me with inputting the channels.  The model is A C1415T Hitachi.  Any help gratefully received and if anyone has instructions for the All in One - all the better!  xx

   I have a sony grand wega kdf55wf655 manufactured in 2005. it has recently started going from power on to power up with perfect video and audio for about 1 min. then it goes to standby mode with loss of picture and sound for about 2 mins. and then back to perfect video and audio. it does this repetitively and sony hotline has no answer. anyone with a similar problem? any ideas?

Wanting to have multiple tv's or pcs showing just one picture.  Let's say, left tv has 1/2 of picture, right tv has the right side of the picture, thereby giving me a bigger picture.  Ideas?  Thanks.
