I need a remote and Manual for 31GT660

Ur girl friend clean around did she unplug the tv.Replug it back later?Bet u she did,that why the tv universal codes is gone.Reprogram ur tv unverisal codes again should solved this problems.Tries push the manual control button channel up like one or two times tv will be in input video again like video 1 or 2.

My only suggestion would be to purchase a multi-functional remote that you could program to your TV. Now some remotes have to be programed buy your old remote. That is not what you need. You need the kind that comes with a little book that will list your tv model number and give you a code (usually 4 numbers) to teach it to talk to your tv.

Your switch at tv are bad, need to replace switches first.

It depends on which universal you are trying to program. There is not a set code for all remotes. Every universal manufacturer has there own set of codes. Thanks for using fixya.

It looks as if your volume up button is stuck, either on the TVs manual buttons or the volume up button from the remote. To check if it's the remote, put the remote away from the TV, either in a drawer or take the batteries out. If the same check the Volume up button on the TV, it may be pressed down & stuck in this position. If this is ok most likely the volume button will be at fault & need replaced.

Hello,
I had the same issue, turns out all I had to do was change the channel to 00, then my games or whatever I hooked up to the component inputs in the back worked like a champ.

Hope that helps.

use tv/video or input button to switch to av input

I had the same problem. I found the solution in this link.

The only thing that wasn't clear was how to get into the service menu. With the TV on, press and hold the MENU button on the front panel of the TV and press POWER then press VOL+.

If there is no input button on the tv itself to change the input then you will most likly need a remote. so you can get a universal remote and follow the instructions to adapt it to your set then you can use it to change the input. (you can get a universasl remote for like 10$) hope it helped

have tech repair your tv the video circuit or related circuit is defected.good luck.
