I turned the TV on and the remote would not operate anything. Managed to change from TV to video1, 2, 3, 4 but now TV is on channel 123 instead of channel 3. All of the buttons on front panel change the video/TV...even Menu and volume controls. I have tried unplugging for several hours but no change.

I went to add/delete channels in my menu on my symphonic and it let me scroll through the channels, make sure you have them all set to add (by pushing the volume buttons to make them light blue instead of purple)....after adding all of your channels (or just the one if you use dish) just power the tv off while on a channel and then power back on and you should have tv.
In the worse case:
It is very possible that the remote recieve on the set has gone defective. It is also possible that there is a fault with the processor in the set, and the remote signals are not being responded to.
As for your universal remote, I don't trust them.
Did you try changing the batteries in the remote? Make sure the new ones are actualy in good condition.
Universal remote control are normally programmed for basic functions, ie. chennel up down, volume up down, numbers, etc.
This is even written in the manual that they do not guarantee that all functionality can be used.
Here are your options:
1. Try all the codes that match your TV, there is a slim chance that the other code have the functionality that you need.
2. Buy the original model remote control.
3. If you know of someone that have the same TV, buy a universal remote control with 'learning' function and copy the signal from the original remote control.
I have the same problems before. Now I use my Casio wrist remote control to copy the special functions such as A/V so that even if the original remote control is lost, I can still use these functionality
