The key wire will disable the contact buttons , but it may be the sensor that is doing this and it would need to be replaced or even the crystal on the eprom or the eprom when connections are attached
have you made sure that the plastic buttons are not pushing on the contact button
did you or can you check the sensor with the diode check on the digital volt ohm meter?

Toshiba model 36a43 The tv stopped responding to remote, bought univ remote does not work, but works with other tv. The menu buttons are inconsistant the volume goes up OR down when pushed, the channel...


What you're describing sounds to me like "Windex syndrome". People sometimes clean the front of their TV by spraying it with glass cleaner like it's a window (which it basically is) and wiping it off. Unfortunately the cleaner can run down onto the circuit board where it damages the switches and wiring. This might be what's happening in your TV, although the same trouble can be caused by other things as well.

The way the front panel controls are wired, a bad switch can cause all of them to act up. The remote sensor is part of the chain too, and if it goes bad odd things can happen. If the set is in an area of high humidity the same trouble can develop because of moisture. One of the switches might not be operating correctly, or another part in the button chain may have gone bad. The microcomputer in the TV may be bad. If you've had a recent severe thunderstorm with nearby lightning, this may have affected the chip.

Try unplugging the TV from the AC outlet, not just turning it off. Let it sit for 5 minutes to make sure that capacitors have had a chance to discharge. Press a couple of the front panel buttons before plugging the set back in. Then plug the TV back in and see if you still have the same trouble. This process makes sure the microcomputer inside is fully reset and often gets the set going again.

If the trouble continues, someone will need to check the front panel switches and the circuit board. That's the area where the cause will be found.

Trying to connect a Sega Genesis. I know it's connected properly to the place where the cable wire goes and then that is connected to the connector. What channel do I go to to play the games?


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.

When i turn the tv. on, the volume line appears all the way to zero. if i turn the volume up, it goes up but when i release the up button the volume goes down all by itself.


It sounds like one of the volume down buttons is stuck in the activate position. The same as if you were holding the down volume button continuously. It could be either the volume down button on the TV or the remote. I would try remove the batteries of the remote then adjust the volume by the TV buttons.


If the volume doesn't go back down then the remote is the problem. In order to fix the remote you may need to take it apart. This is normally easy to do just locate any screws that may be holding the remote together. If you don't see any screws then you will need to pry the two sections apart. Separate the circuit board and rubber buttons and clean them both with some rubbing alcohol and reassemble it. If it still has the volume issue you may need to replace it.

If the problem persists with the remote deactivated then it's the volume button located on the TV. That is a little more difficult. You can try wiggling the button or some canned air (used to clean computer keyboards) to blow it clean. However it may need to be disassembled to gain access to the switches for proper cleaning.
Hope this helps.

My volume button goes all the way up to the max and stays there and sometimes my mute won't work how do i fix the problem


It looks as if your volume up button is stuck, either on the TVs manual buttons or the volume up button from the remote. To check if it's the remote, put the remote away from the TV, either in a drawer or take the batteries out. If the same check the Volume up button on the TV, it may be pressed down & stuck in this position. If this is ok most likely the volume button will be at fault & need replaced.

Sound goes down


The down button on your remote might be stuck down. Try taking the remote out of the room or cover it up with something. Then turn the sound up at the set and see if it stays up. If this doesn't work, the down button on the front of the set may be stuck or have leakage in the button. This would require taking the set to a service shop. Another possibility would be a loose ground on the CRT dag which can cause this. this also would be something a service shop would need to take care of, as you could get a shock if you attempt this repair yourself.

Why does my RCA TV cycle through channels on its own?


this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

If volume shows erratically behaviour do the following:

  • Take batteries out from remote and check if it is a remote problem.
  • Try pressing and playing volume buttond on TV, see if it can be a button.
  • If it is a button remove front panel and clean button contacts with circuit cleaning solution.
  • If all the above did not work, it is either a faultycontrol panel or a faulty audio pcb on your tv. Them both must betested (control panel it is an easy test if you know how to use amultimeter)

If you need replacement parts enter model here

If you need to call a technician you can ring the number listed on your owner manual
