you must have blown a fuse. you will have to have a tv technician check it out.

In most cases, this requires soldering a new RF connector into place. Otherwise, the tuner will need replacing. Good luck.

When you have your converter box hooked directly with coax to your tv, is your antenna then plugged into your converter box in the "antenna in" port? What do you mean by it doesn't work? Does it say no signal? If so, you just need a stronger antenna. If not, you may have a defective box, bring it back to the place you got it and see if they can help.

the only way to turn i to the input is by pushing the button "input" or "game" on your remote. "input 1" is the back connectors and "input 2" is the front connectors. "GAME" is also the front connectors but it turns that "game mode" on that is in the picture settings. suggest you read the manual that came with the tv too. it explains this all in there with pics and stuff.
if you lost the manual here is a link to it on there website.

hope this helps.

first question. you need a remote to get to the inputs on the tv. some reason they made it like that. get universal remote and try it if don't work return and try another brand ect.

second question.

try another code maybe or jsut return it and try another remote. the rca 15-2115 5 device remote i have workes with the "A/B tv?vcr". on the origional remote that comes with the tv there are actually 2 buttons. one is called "input" and the other is "game". the only difference between them is turns the game mode on and off in the picture menu. i really don't like haveing "game mode" on because it makes the picture looks bad to me. you can turn it off in the picture menu easy.

sorry but i think your picture tube went. maybe use warranty or get another one.

You may want to change the batteries in the remote and reprogram it. Let me know if that works. kim
