This could be a cold solder or something a simple as a fuse inside the telly how old is the telly and are you confident in taking them apart and looking for the problem yourself as these tellys work at a high voltage witch does kill they are still live even after they have been unplugged for 24 hours so i would leave the telly for 24 hours then i would take the back off and where the power lead goes into the boadr there will be two fuses check both of these and replace if needed if you are not confident in taking the unit apart take it to a shop as their is a lot of things you need to undo but first try the controll if you cant do nothing on controll then it is fuse or a solder problem could even be high voltage problem have you still got the stand by light on the set if you have then it is a high voltage problem witch is difficult to tackle without proper testing equipment if you have equipment i could talk you through how to do and what to test but if you by the equipment you are talking a few grand it shouldnt be that expensive to get repaired at shop i would have thought about 75quid witch is cheaper than destroying the set if you dont know what you are doing post back if you need to hope this is some help.......................................................

    best thing to do is go to the repair shop and let them have a look at it as if you cant see any visable problems ie heat problems and if the telly stays off all time and dont come back on after being switched off for a few hours if you still have a standby light on the front then it is going to be a high voltage problem witch you wouldnt find yourself as this can be hard to find but the have the relevent testing equipment to test each individual part for you just be carefull its not just a solder problem and they tell you it is something else best thing to do is ask them to let you see the repair strait after they do it as with these telly some parts are nearly as expensive as the telly itself so be warned sorry couldnt be any more help
