Hello, This might be a board with a loose connection or a faulty capacitor on the power board or one of the immediate circuits attached to the power supply board. I would suggest that you have this serviced by a qualified TV Technician. However if you wish to do this yourself, you need the following equipment: 1) Multimeter (to measure the voltages; AC and DC on the various test points on the boards) 2) Oscilloscope (to measure the startup and shutdown circuit ramp voltages) 3) Isolation Transformer (to isolate the Tv from the AC circuit that the test equipment is on) 4) Service manual or schematic diagram (to show where the test points are and what signals and voltages to expect) 5) Signal generator (to generate reference signals for servicing the TV) Now if you know how to use these pieces of equipment your are ready to start, if not again I would advise you to have the set checked by a qualified TV repair technician. I hope this helps Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

Follow the steps below
1. Select any channel on the TV.
2. Point your Sky+ remote control away from the TV and press the tv button.
3. Press and hold down the Select and red buttons simultaneously on the Sky+ remote control until the red light at the top of the Sky+ remote control flashes twice.
4. Input the 3 digit number from the Sky+ remote control codes then press the Select button. The red light at the top of the Sky+ remote control should flash twice.
5. Point the Sky+ remote control at the TV and try the volume button.
If this works try the other TV functions.
If these work then the correct code has been selected.
It's important to note that not all TV functions will be supported by the Sky+ remote control e.g. Picture in Picture.
If all functions do not work correctly, then repeat steps 1 - 3 and work through all the relevant 3 digit numbers from the Sky+ remote control codes, until you find the code which supports all or as many of the TV functions as possible.
Please note: In order to operate both your TV and Sky+ with your Sky+ remote control, you will be required to switch modes e.g. to switch on your TV from stand-by, you would need to press "TV" followed by the "Stand-by" button. Then to change channel on your Sky+ you would need to press the "Sky" button followed by the "TV guide" button.
