Is there a microprocessor/software reset procedure?

074,058,017,037,028,082 are the setup codes to check with this brand TV. If you wish to get more details, check this link.

Use the remote dishnet to automatically detect your code for the tv. Most of the time the procedure is on the remote.

it could be sensor on tv

try holding remote in front of a video recorder and if you push button on remote and view through video recorder you should be able to see the light blinking coming out of remote - if you see the light coming out of remote and it is still not working then the tvs sensor went bad

besides trying to unplug tv for a few minutes there is no reset for this issue

Hello

Just buy one Philips Universal Remote control Model number [CL 034]. You can synchronise it with your Symphonic Combo by entering one amoung the following codes. Proceedings are also given.
Note: Switch OFF and Switch On your combo, before entering each code.

Three digit codes for Symphonic are:-
033/ 053/ 189

Four digit code for Symphonic TV/VCR combo is:-
0227

Four digit remote codes for Symphonic tv are:-
0053 0189 0227 0456 0024
Four digit codes for Funai are:-
0051 0189 0053 0227 0456 0042

Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

You can also check according to the catelogue of that remote control also. The above given numbers are most common for all universal remote controls. OK.

These are the steps on how to program your RCA Universal Remote Control to your Symphonic TV.

1. Press and "HOLD" CODE SEARCH.
2. Press and release the TV button. When the TV button flashes proceed to the next step.
3. Enter the three digit code. In your case, the code for the Symphonic TV are 064 or 076.
   
4. Release CODE SEARCH.
5. With the TV on, press another button, for example CHANNEL UP. If the TV responds, no further programming is required. If the TV does not respond, repeat steps 1-5 using the other code number.

Good luck!

Hold the set up button until the red light stays on on the remote. Press power until the TV responds. My sleep timer displayed after 23 presses (hotel room Magnavox TV). Stop pressing remote. The red light will then flash a few times once you stop. Problem fixed.

Given that both remotes work with TV2, more likely the IR sensor on TV1 is defective.
The problem could also be in the microprocessor itself as well.
