When switching T.V on, the sound works but without a picture
In the morning when the TV is switched on. the sound comes on but without a picture and the problem persist even if I press other buttons on the TV remote control.
I have to turn off the TV from the remote control and the wall socket switch and turn them back on for about three or four attempts before the TV operates properly. When I phoned the company as the TV is only eleven months old and still under guarantee I was told that it could be the power supply. I am not sure if this is correct or not.
Any suggestions to this problems is greatly appreciated.

I personally dont think its the power supply, you're getting power, and I could be wrong, but it sounds like bulbs or modules that enable your "picture" is faulty. Check the owners manual for troubleshooting tips too, companies are making flat screens so fast nowadays that they install faulty parts and don't even realize it.

Connect the TV to another power outlet that you are sure, works. Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.
If you have sound, then your tv doesn't need tuning. Shine a bright light onto the screen, can you see a very dim picture? If so, your backlight has stopped working. This is almost always due to the inverters failing and can be repaired.
Sounds like the video board when bad. I would say the TV went defective. Use the 90 day warranty to exchange for a new one.
Always use warranty at this point because the newer TV coming out in these days have very lame warranty.
This sounds like a power supply problem. I would advise that you get a qualified TV technician to troubleshoot this problem. The reason being is that the TV does not come on at all. The problem might be the main power board (AC to DC) or the secondary power board (Switching Power Supply and distribution board). Have these checked first.
