Trying to connect streamsmart to older symphonic tv. Picture on screen rapidly jumping up and down. Can't program it. How do I make it stop?

If you are seeing snow on your Symphonic TV screen, it could indicate that the TV is not receiving a signal from your cable or antenna. Here are some steps you can take to troubleshoot the issue:

1. Check the cable or antenna connection: Ensure that the coaxial cable or antenna is securely connected to the TV and the wall or source.
2. Run a channel scan: Perform a channel scan or auto-programming to ensure that the TV is tuned to the correct channels and that it is receiving a signal.
3. Check the TV's settings: Make sure that the TV's input is set to the correct source, such as cable or antenna. Also, ensure that the TV's settings are not set to "mute" or "no sound."
4. Try a different device: If you have another device, such as a DVD player or gaming console, try connecting it to the TV to see if it is able to display video and sound.

If none of these steps work, you may need to contact a professional technician or the manufacturer for further assistance.

Vertical jumping may have a vertical hold issue, horizontal may have a horizontal hold issue. Most older tv sets will have some knobs or adjustable screws for vertical and horizontal hold. Turn your set on and check for these knobs on the back of your set and adjust until your picture is in as well as you can get it

Check the set by any other cable connection or use any AV input if you receive proper picture than your TV set is o.k,problem is with cable box,contact cable service provider to solve the problem.Also check by simply removing cable box the message will disappear.

Hi,

The input from the Sega wont be on any channel number - you need to select the correct input for the Sega using the "INPUT SELECT" button on the Symphonic remote control supplied with the TV. Switch on the TV the Sega, then press this button repeatedly until you can see the picture from the Sega.

- If you are using the sockets on the BACK of the TV, the correct input is "VIDEO 1"
- If you are using the sockets on the FRONT of the TV, the correct input is "VIDEO 2". You can also switch to the "VIDEO 2" input by pressing the "GAME" button on the Symphonic remote - if you still have it.

If you don't have the Symphonic remote, look for a button marked "INPUT" or "SOURCE" if you are using a universal remote.

If you don't have any remote for the TV, you will only be able to use the sockets on the front of the TV. You will then need to switch to "GAME MODE" by using the buttons on the front of the TV:

1. Switch ON the TV and the Sega;
2. Press the MENU button;
3. Press the VOLUME UP button to open the PICTURE MENU;
4. Highlight GAME MODE using the CHANNEL UP/DOWN buttons;
5. Set GAME MODE to "ON" using the VOLUME UP/DOWN buttons;
6. Press MENU again to close the menu

You should now be able to see the picture from the Sega. If not, check you have correctly connected the Sega to the TV. When you have finished using the Sega you will need to use the method above to switch game mode off again.

Hopefully, I've covered every possible angle. If you have a different Symphonic TV model from the one listed above (ST420FF), the method should be similar, but if you have any difficulty, please post back for further assistance.

BElectric.

u can go 2 buy a universal remote with a handbook 2 tell u how 2 program it lol.b alot easier.that way if u have dvd & vcr...it can b programmed 2 operate it as well as the tv!universal remotes r the best sollution lol.lazier the better lol.

i dont know how to program the remote for tv..i got the codes

is there an auto scan option? if so turn it off and do it manually using the up down buttons

if line is across screen thats virtical circuit prob. need tech or up and down horiz circuit. need tech

Sounds like the IR pickup has gone bad or the supply voltages feeding it are opened. Sometimes cleaning the screen with windex it tends to drip inside as it follows the picture tube down into the set . Most of the time replacing the IR cures your problem. Good luck
