you have checked all sleep timers etc<br />and that your video signal cable are all good <br />if all the above is ok <br /><br />then you need to take it to a repair man <br />did you but it with your credit card if so some credit cards offer extended warranty they just dont talk load about it <br /><br />you can also contact the department of fair trading to see if there is anything they can do <br /><br />as the warranty period is a min of 12mths as it depends on a case by case and the value of the item <br /><br />good luck
