The input function is not working and the t.v. is on but no picture. Blank screen. Was working last night just fine we tried to hook up Xbox and when the input button was pressed screen went blank. any ideas?

Hi. It could be one of a few parts
I.e main board you say the TV stays on I.e standby light stays on OK.
if so try shining a torch into the screen while the TVs on see if you see any pictureor menu when pressed on remote .if so possibly backlight issue.
try darken thye room your in when shining a torch at the screen
. What's your make and model number
as it could be tcon or main board issue even

Your problem is in the TV. I'm not familiar with your TV, but you should look for an option to turn it to normal or to try and scan for channels with xbox plugged in and running. I'm pretty sure that if you get HDMI cable, your problem should be solved.

Hook your Xbox to tv via HDMI, then hook TV to reciever through digital optical or composite cables. If you try to get your picture through receiver first, you may get picture and sound but, sound may be delayed and picture might not be the best. Bettter to run through tv first then provide sound to receiver.

Did you switch the Xbox HD switch to the off position?

Look like ur Xbox 360 AV RCA cables is not making contact to the input board very well.Take some rubing achahol cleans the all those input holes,take the RCA AV connections make couples twises to the red,yellow and white,will help.Make contact with ur input board it should work.

Needs to be reset with console.

Try this link,should help you.

check the invertor boards resistors they power the back lights
also check for any capactors that have blown (raised tops) they look little bateries

PS3 is one of the most amazing gaming device but like other competitor gaming devices (Xbox and Wii) It also has some problems like No Display Problme. You may check out the informative blog post at PS3 Repairs blog

Hope it helps to fix the problem................

already solved it. thanks. i couldn't see the xbox settings blade because of the blank screen so switched my component cable to the tv setting instead of the hdtv setting, then i could see the dashboard in non-hd and switched the resolution to 720p while simultaneously switching the component cable back to the hdtv setting. that worked.
