How to connect xbox 360 to Vaio pcg 252l

I couldn't find out if the Vaio pcg 252l was either a monitor or laptop, but if it is a laptop, I have to dissapoint you because there is not possible to do, because the laptop isn't made to be used as a monitor, but if the Vaio is a monitor(basicly a screen), then all you have to do is to either connect a HDMI cable from the xbox to the monitor, or you can use a SCART cable, all depending on which are available on the monitor/xbox.

HDMI have better quality, in case you could use both cables.

When i start the machine up it starts up... then the image gets staticky,,, then all u can see is white lines and no image, im not sure if it is the video card thats causing the problem. Need to fix t


If you are able to connect an external monitor, do so. (If you can make it a newer lcd type) Sounds like your monitor's display is set to the wrong setting (refresh and pixel) With an newer lcd, you should be able to see your screen and reset the display to the lowest setting. Reconnect your Sony monitor. (if the external work and you are able to reset the settings, you do not need to power off your pc, just switch the monitor cable from the external to the regular monitor.

Good Luck

I checked the ram modules and the thing is when i press to start the computer the led on the screen doesn't turn green , i get either one long beep or 3 beeps, and the screen remains black and it doesn't...

One long beep + 3 short beeps denotes a video problem for Sony Vaio. Unfortunately it doesn't get more specific. If you have a video card, try re-seating the card. Try using a different monitor. Try upgrading the drivers (probably here: ) of course you will have to go to a different PC to download them onto a CD/dvd and try to run them. You might consider trying to boot into safe mode and doing a system restore. It could be many things. Without more information I can't really be of much more help. Hope one of these works for you.
Good luck
