I think your TV is in the A-V mode. The X Box is going into the TV through the A-V jacks. (AUDIO/VIDEO). You should be able to switch the set to tuner mode with the remote. Look for a button labeled input or go into the menu and look for "input". Stargazer

Those are called retrace lines. The electron beam has to go back
to the beginning of the screen as part of its raster scan.
Normally it is turned down so that it can't be seen. There is a
little adjustment knob on the high-voltage flyback transformer called
"screen" that will hopefully adjust this for you. If that doesn't
work it is an indication that the high voltage circuit is dying.
Hop Ya Fix It.

Philips 27TS54 c101 27B800-7562 White horizontal line in the center of the screen. Color is present in the first half inch of the leftist corner of the horizontal line.
Audio is present and controllable. The green power led from a cold non plugged in state remains solid until CRT goes to ignite. A click is heard then the green power LED blinks.
I found service manual diagram of repair part or parts and install instructions
I request any info or tips you might have pertaining to this problem

On the CRT circuit board(picture tube), you will find R3340, which is a 10 ohm 1/3w resistor. The location of the resistor is printed on the bottom of the ckt board. It is burned open, replace with a 10 ohm 1/2w resistor. This will solve your problem. The original resistor was sized too small, should have been a 1/2 watt. This resistor is mounted standing up on ends. Mount the replacement resistor the same way. Be careful and don't get the circuit trace too hot and damage the circuit trace. (it's very small) The resistor is located on the crt(cathode ray tube), pcb(printed circuit board) socket. The resistor supplies apx +200v to the collectors of the r, g, b, video driver transistors. If this voltage is low, it causes excess brightness(excess beam current), causing the set to "shut-down". If the shut-down is too quick, you will NOT see the excess brightness, because the picture tube has not warmed-up enough to display anything on the picture tube. To see if the set displays "excess brightness", you will need to turn the set "on" about 5 to 10 times. This will heat the picture tube enough to display "excess brightness", IF that is the PROBLEM. Of course, there are OTHER defects that will cause a tv to shut down. There are built in safety circuits, that will "activate" if excess voltage/current or heat is detected anywhere in the set.
My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008
