There is a processor that takes care of all the TV controls. A tech will need to replace it.

Tv does not respond to any input only shows nosignal to any device


Did the TV's source get changed? If you use the Television remote and find the source or input button which switches between the video sources for your TV such as HDMI, A/V, Television Tuner,, VGA connector or Component video. If your using a cable box that remote only controls the cable box and possibly the TV power and volume but the cable box remote does not change the source input of the TV. Most Cable boxes rebroadcast their video on a specific TV channel and your TV must be set to that channel to receive the signal from the cable box. Let me know if this helps you out.

ILO LCD Color HDTV does not change channels / volumn...just turns on/off


The symptoms your TV is experiencing is due to a power supply that is not longer providing the 5 volts properly to the circuitry.
It seems to be a common failure on these TV sets.

Sharp LC-37DB5U stuck on one channel. Won't respond to anything. Put in a new motherboard and same problem persists. Sound and picture are fine


I could be wrong, but it sounds like the TV hasn't gone through channel setup. You have to do this in order for the TV to "learn" the channels, assuming you are using cable. If you are using cable run channel search in the setup menu and see if that changes anything. Can you change channels by manually entering in the channel # and hitting enter?

Orion TVD2710. Lost remote, can't change signal input


I would suggest you try to find a universal remote that has an "input" or "source" button and program that one to your tv. By pressing the "source" or "input" button, it will change the input to the tv. I hope this helps! -Der Strom

No response to any button on remote or tv except power button

It sounds like you are on one of the video inputs of the tv. Look for a button that says input, aux, video, etc. on the set or remote.

Powers on will not change channels or video inputs


Is your remote programmed properly? If it is a universal remote, try setting it to one of the different codes for your brand. Sometimes the power and mute buttons and things like that are the same for all different types of a brand, yet all of the channel and volume things are different. If it's the remote that came with the TV, then I would try to get a replacement, as it could be faulty. Hopefully this problem is with the remote, and not the TV. Find if this is the case by using the volume/channel buttons on the TV itself. If they work, then you can be reasurred you don't have to call the TV repairman, and you will probably be able to fix this problem yourself.
