My Tevion LCD 32081D TV is very slow to start up. After a number of minutes a coloured screen appears. The screen then changes colours over the next 5 to 10 minutes. I then have to switch off the mains supply to the TV and turn the mains supply on again at which stage I turn the TV on again and with luck the TV comes on.
Can anyone help, I have found it difficult to find any service manuals, circuit diagrams or information.

Have you tried re-setting it if there is a reset button?
Alternatively, try resetting it to factory condition and then re-install all your channels etc. Just a couple of ideas, no guarantees it will work. Worth a try.
