Hi when i connect my asus pc to my tv to show a powerpoint it works for about 10 mins then tv says no signal and counts down from 5 mins why is this what can i do?

Hi , just access the monitor on-screen display (OSD) menu and ensure Monitor input mode is configured for HDMI ( Asus speak the " desired input source" ) - Input select is accessed under tv with arrow icon : change from vga to hdmi

Have you checked these?
1. Input settings in the TV,
2. Cycle the laptop output (laptop screen, external screen, both)

Microsoft Powerpoint is not a free programme. It can form part of Office.

go to the powermanagement in the control panel. In it check the settings to turn off system when i press, or shutdown the pc after 30 min change it to never, and turn harddisk off to never. and remove the system from hibernation

yyou could remove the hd and hook it up to another pc then transfer your files

Please check whether the monitor is set to the correct settings. If you feel its incorrect, most LCD/TFT monitors come with an auto set up button which will restore the display to one that usually works. In case it still doesnt work, you might need to connect your pc to a different monitor and check the display settings. You could also try to download the drivers for this monitor and then re-connect the monitor and see if it works.

First try another signal input like a DVD player or other source, is the signal displayed ok? Then you have lost the signal on one input from whatever the device is.

I've settle my problem. Set the correct VPI and VCI provided by ISP.

Your son more than likely changed the input source. You may be able to change it back by pressing the channel up/down button or you may have to enter the menu on the tv and change inputs that way. PS's will usually connect using a video input using a red/white/yellow cords. You may also want to ensure the connections are in their proper place as I do not know how savvy your son is at changing the setup over to play his PS. If you use a modulator to connect to the TV-either the PS or aerial- ensure that it is powered up also. I hope this has been of assistance to you and thanks for using Fix Ya. If I can be of further assistance let me know.
