Does the screen go blank after the computer has been sitting unused for a while or is it immediately blank and does not show a picture. If it goes blank after a while, look in your power settings under control panel on your computer and set the monitor cut off to NEVER, also check your screen saver settings. If it does not show a picture at all check the user manual of your TV to see the supported computer resolutions and then check under display settings on your computer to see if the resolution that you are using is compatible. Hope this helps.

I have a new sanyo 32in flat screen for a monitor my pc loads up and it seems fine then when the log in screen should appear it goes black if i hook up a diff monitor it shows up


This most likely happens because the pc is using a resolution or frequency that is not supported by the tv/monitor. The resolution when starting pc is different than the resolution when logging in.
On Win XP right click on the desktop background, and choose properties from the pop up menu. Open the far right tab and change the screen resolution to 800 x 600. This is highly likely to work on the tv/monitor. [Vista or Win7 right click and choose personalize to get to resolution settings]
Connect to the monitor, restart pc, and you should be able to then see logon screen. Go back to the resolution setup screen and experiment with different resolutions till you find which works best for your display. You can pick a resolution and try it, then it will ask if you want to keep the setting. If you do not answer in 15 seconds, it will revert automatically to where it was a moment ago. So if the screen goes all funny or blank, just wait and it will come back.
Note that your display video card may not be able to support the optimum resolution you need, in which case you will be under utilising the screen. Everything may appear too big or stretched in one direction. In that case you will need to upgrade your video card to make full use of the screen capabilities. You should consult any documentation which came with the monitor to see what is optimum pc resolution to use, and bu video card appropriate to pc and monitor.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Samsung 50 inch plasma tv screen goes blank temporarily


This could be caused by a loss of video signal either from the connection or from the source. The TV may have detected an error which caused the screen to go blank. If this occurs again, check the cable connections and see if having the TV unplugged overnight resets the TV and eliminates the problem.
