My sansui sv2136 is having a problem..keeps auto tuning to find new stations by itself, volume keeps fluctuating, and the tv menu keeps opening by itself

First make sure that the TV is set to the TV source (DTV or TV), depending on if you are looking for digital signals or analog. The top-most button on the right-hand side of the TV (as you face the TV) will let you navigate through the source list. The equivalent button on the original remote is to the upper right of the arrow keys. Press OK on the remote to switch inputs. Note: the Volume + does the same thing. The Channel +/- buttons on the TV let you navigate to a menu item. Make sure that the aerial antenna connection is secure. (Note: TV antennas with amplifiers can have the amplifier fail. Try a direct connection to the antenna without the amplifier, if no channels are found.)

Now, press the TV Menu button (on the remote, it's on the left side above the arrow keys). Alternatively, press the Menu button (the second button from the top on the TV). Use the left/right buttons (Channel buttons on the TV) to go to the Channel menu item. Press the Down button (volume down) to enter the setup section. Select Auto-Tuning and press the down arrow. Press OK or right arrow to start searching for channels. (If you only want to look for digital or analog stations, use those setting options instead of Auto-Tuning.) Wait for the search for available stations to populate. Press Exit or press the Menu button repeatedly to exit the menu system.

ManualsLib has the user manual for the L26DVDB20 here: https://www.manualslib.com/products/Logik-L26dvdb20-3947852.html . The page for auto-tuning is here: https://www.manualslib.com/manual/990700/Logik-L26dvdb20.html?page=19#manual .

I hope this helps.

Hello wilson_deniz,

Welcome, and thank you for using FixYa!

The maunals you seek can be found at the link I have included below. But you will have to locate your Model Number on the back of the TV. The manuals also cose $4.99 each.

Small price to pay if it helps you fix the TV.

Have a great day!

If your set does not have a menu button built into the set your out of luck unless you can find a replacement or universal remote.

Toshiba TV 2151TB Tuning
Press remote button adjacent to the picture brightness button.
The symbol of a clock appears.
Press the button again and the >>> symbol appears, this is for course tuning.
Touch the Increase Volume button and auto tuning starts.
When a station is found two green underlines appear.
Type the station number i.e.for 2 type 02, this stores the station.
Touch the Increase volume button again to find the nexr station.
Upto 39 stations can be stored.
Fine tuning of any station is achieved by pressing the tuning button until three blocks sysbol is displayed.
Use the Increase/Decrease Volume buttos to fine tune the station.

On later model Sansui tv's, you can bring up the menu by pushing both volume buttons on the front of the set at the same time. After the menu is on the screen, you can navigate using the channel and volume buttons.

please check web site for any thing in remote. www.remotes.com and give model name in search. hopr this will help. good luck.
