Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.
When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.
It doesn't matter which button is stuck, any of the symptoms you describe can happen.

I have an easier solution, First I want to thank those who posted the solution that the problem is on the small switch board mounted right behind the switches under the picture tube. I figured that might be where the problem was but it's better to to see it confirmed. I thought the problem was more complex like maybe an IC chip got zapped or something but there are none on that board. Only 6 switches, the infared sensor, 1 capacitor and some resistors. I am convinced that in my case at least the problem is caused by humidity. It happened last year constantly durring humid weather in the summer and only a couple of times over the winter when the air is dry and cooler. I did figure an easier way to disconnect all the switches without unsoldering. After you remove the board, flip it over to the solder side and see where the wires connect. You will see them labled GND - KEY - +5 v - LED and IR. The one you want is labled KEY. You will see on the other side this wire is second from the end . Just separate the wires a bit and cut it. That's it. Just be sure it is the one marked KEY. This wire goes thru a series of resistors and the switches and nothing else. Just cut that one wire and put a piece of tape over the cut ends and thats it. it's a lot easier then unsoldering all 6 switches. And if you do decide at some point later to replace the switches, it's easy to resolder the wires and tape it. I did it this way and my TV is working perfect. I was done in ten minutes. You can only control the TV with the remote but so what, thats all we use 95% of the time anyway. I hope this helped you.

the small signal board usually causes those symptoms.
