I get sound but no picture

Hi,
You said the sound works but you get a blue screen on the TV, check your TV if it is set properly.
Make sure the Input is correct on the TV to shoe the Video coming from the console and check if the cable connections are properly connected to the TV and the console video output and input.
Also try it on a different TV to see if the issues is with the TV or the Console itself if on a different TV and the issue is still the same the issue is the Video output from the console but to check further more try a different cable, borrow one or maybe buy a new one just to see and eliminate possible causes of the Blue screen issue.
I hope this helps.

First take the red white and yellow cable from your ps3 a/v cable
and plug that in to any tv that has these inputs and select the correct
a/v input on your tv. You should get a picture if not swap the the
cables for another set. This will establish your problem is with
the ps3 setting and not a failure of the console.

Then goto video settings menu on the ps3 and select hdmi out
not standered tv . The picture will disappear and your hdmi out
put should be active if you want to return to standered video using
the Red white yellow plugs again just turn off the console and
then hold the power button down for 5 secs this will reset the
console to standered video out.

if you need more assistance feel free to ask.

take the cords out of the back of the wii for 30 sec.

Have you changed Video settings or swapped from a HD TV?
Hold down power button when switcthed on from the back until you here it beep (approx 5 secs) this will reset video settings

lols check ur wires bro. the basic yellow, white and red wires. make sure the yellow i belive is connect properly. if that doesnt work then go to system settings and check for a solution there

This is because of a resolution problem. Just hold the power button for 5 secs, it will reset the PS3 and you will be able to see the picture.

my dreamcast console has sound but no video, it will go to the time setting scream but no responding after that point

since you bought this console used, it maybe set to HDMI 1080p/ 1080i/720p output(by the original owner) and if your TV does not support this there will be no picture, the only way to lower the output resoloution is to get into the options menu but to do that you will need a freind with a tv that supports whatever resoloution its been set too.
