How can I switch inputs on a Sylvania 6420FB 20" TV with no remote

This problem may be more complex than just the selection of a channel to receive video. The first problem is what channel to receive the video. Usually its received on channel 3 or 4. You select that on the video output and match it on the TV. That assumes your recorder is attached via the RF (antenna) connection. If its hooked up via the component connect then you must have a remote to select IN1 or IN2 on the TV to receive video. Remote controls are available on line. Do a search on your TV model and remote control.

WITHOUT a remote

Try website like Remotes.com to buy the tv original remote.

Hi, well ALL TV's can be controlled from the Buttons ON the actual TV itself, look carefully on the TV, you will find a set of buttons, usually about 7. They should be marked, ON/OFF, CH UP, DOWN, MENU, ENTER/OK/SELECT, VOL UP/DOWN. Now Multiple presses will access differing features on the set, usually after pressing the ON/OFF button, you press the menu button and select your Input, Tuner, external, etc, once set, you Change the channel with the UP/DOWN key, and the Volume with the -,+ Key.


It's all in the user manual in the download link below.

Remote codes are part of the universal remote, not the TV. Try the Sylvania codes in the manual with the remote. If the code is not there, the REMOTE does not have the instructions to run the TV.

try changing the channels until you reach 2 and go past it.

During a recent move the remote was lost. I have the 6420FF in my son's room and trying to set up dvd and wi console set up, but cannot adjust tv via menu button on tv. Is there any way to set-up game system and/or dvd without remote?

Unless the TV has a front-panel menu button and allows you to switch modes from there, you are out of luck. There are two possibilities. One is to try another replacement remote. If you get a universal remote made by the TV manufacturer (Magnavox), it may have buttons that will work. The other option is to purchase an RF converter, which will cost around $15. This will take the video/audio signals from the game and convert it to a channel 3 or 4 signal you can then tune in on the TV. The picture won't be quite as bright and clear as with direct AV input, but it will do the trick.

Trata con esto.
Presiona el boton Code search y mantanlo asi hasta que el led se quede encendido suelta y presiona el boton TV despues vas a presionar y soltar el boton Power hasta que el televisor se apague despues presionas el boton enter y el codigo queda almacenado.
El Tv tiene que encenderse primero manualmente.
