You need to take your TV set to Service Center, because the inner parts, especially the flyback transformer, been damaged or worse, the connector broken, that's why you can hear the noise.

Try pressing the input, game, or aux button on your remote. If that doesn't work try a channel like 2, 3 or 4.

Buy a universal remote, the codes for each individual TV are in the manual, and program that remote to work with your current television.

If you mean you lost your RF converter, which enables you to connect your game to the antenna input, you can connect your game to the connectors on the front of your TV to video 2 input with a Video and Audio cables. After that select video input 2 from your remote controller or TV buttons. You can also connect it to video input 1 at the back of the TV.

As silly as it sounds some Symphonic TV's use the code 0000 as a work around.

Try 520, 904 or 906.

are you the one with the RCA remote?? I found the program procedures if not please ignore me

Find an Input button, If you do not have one, get a R/F Modulator and swap out your TV connection and set the channel to 3, or 4 depending on the settings on the R/F Modulator. Then swap the cables back again to switch to TV

It is both. It is your channel source that really matters. If you are in the US all channels went digital just a short time ago.

What kind of code do you need? If remote control and tv , tell us the brand and model of TV as well as Remote control

Normally this is a internal regulator problem and can't be fixed without taking the shop
