Try to unplug it and a cable or sat box if used from power for a while to see if a reboot will help---also the fact you cannot change channel etc means the set experienced some kind of glitch.

Be sure your channel settings are correct and that you have proper orientation of the hook up cables. See if your remote has a video-mute if so turn it off...a video-mute will produce a blue or black screen. To be sure its not the tuner that's enter the menu screen if you can see the menu then the tuner is ok this means the down-stream video is functioning. Be sure to have all your input devices set to the correct output ports. If all check good and still blue screen then the logic section is not processing video codecs and needs servicing.

Help I only have a blue screen


Try adjusting the settings to factory settings. Change the input to some other device. If problem persists, there is something wrong inside. It is better to show it to a qualified service technician.

Blue screen on my haier 37 inch tv


my tv just went to a blue screen one day. I can turn it on and then it will just remain on the blue screen. Any button (except the volume) I push on the remote comes up on the screen "no signal". What would you suggest? I have been reading about replacing a fuse or board? Most of those are on the 42 inch version---I have teh 37 inch version.

Channel keeps changing


It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?

Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions.

Sharp Aquos LC-42D62U VOlume Control


OK guys I'll save you. The tv is in hotel mode. To get it out from there you have to go in service menu but DO NOT CHANGE ANY OTHER THING IN THERE, only what i tell you. With the tv on and the K letter on the screen press in the same time vol- and ch- on the tv set. Now you'll be in service mode. On the remote press down arrow (not -channel) and you'll see up industry init. go there with ch- and press vol+ and enter. let the tv like that for few seconds and the tv will go green and hopefully industry init succsesfull will be on the screen. After that unplug the tv and replug it. Done!
