Hi, welcome to Just answer
Please tell me its complete model number
and how old is it ?
what all is connected to the unit ?
and is it same regardless of which Device you are watching ?
OK, press the TV button and Input button to check and select correct input let me know how it goes
If you press MENU on TV does the Menu appear on the screen ?
OK, are you willing to repair this yourself ?
This usually happens when the set is cold...after a while it gets warm it might show the picture again, the problem is either with the power supply or the main board...after leaving the unit unplugged for few hours, you will have to take the back off and check the power supply board...the cost of repair will be around £140 all inclusive
OK, You can get back to me if you need any assistance and I will help with no additional charges.....Is there anything else I can assist you with today ?
