What you have there could be one of three possibilities. Micro, eprom or tact switches... Tact switches are the small contact switches behind the buttons you depress to turn the volume up and down or change the channel. Sometimes these small switches can become contaminated or breakdown due to corrosion. What we call in the industry a windex syndrom, because the older crts on some models had the swiches exposed just below the lower ridge of the cry where when cleaning the screen windex could drip down onto the switch and cause the corrosion to begin.
Eprom is another likely suspect. This Ic is responsible for storing an array of information including customer settings and other logics convert what the eprom stores into electronic pulses for any number of fuctions. For example press the volume down on your Tv and the eprom has the information to show you the volume bar, the level the volume bar was last set at and the increments at which you are reducing it realtime.
The Micro is another possibility. It acts like a traffic cop engaging various circuits to do or not do something according to a preset list of conditions. Timers, looking at a particular input or yes even bringing up the menu is tasked through the micro controller Ic or micro for short.
The fact that you can eventually get the unit to operate suggests that something in the logic circuit is failing and will in all likelyhood continue to do so until eventually it doesn't work at all...

Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.

Solution that worked for me:
Beware: Although the process should be safe, it technically voids your warranty.
Enter the service menu:
1 - turn of tv with remote
2 - press and release in the following order on the remote: Info, Menu, Mute. Make sure remote is pointing at the tv
3 - turn on the tv from the remote
4 - you will see the service menu. using the down arrow on the remote select the Reset option. Using the right arrow button at this point will do a hard reset.
5 - Wait a few seconds, turn TV on
6 - you will have to rescan analogue and digital channel but it should be working now.
