20 Most Recent Sylvania 6420FB 20" TV Questions & Answers

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.

Try your format button... or your wide/size button... they're all a bit different but they all have different screen size capabilities.

hope this helps

Check its secondary power supply voltage from SMPS power supply. Check the smoothing capacitor connected to secondary power supply voltage, replace it.

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.
