@moggy01 "No lights showing at all " always start with the power supply. Make sure you have power going to it. Then check the caps and fuses on the board. Work your way forward from there. follow the power rails to see where and when the power gets lost.

Thankyou for being helpfull @oldturkey03 i have read the chart and board shows no voltages ,main fuse and mosfet n diode and bridge rectifier is faulty so i have sent board for repair for £50 and then the tv will stand me at £100 and feel it is a bargain as i got sound bar wi-fi dongle and 3d glasses with it all sharpes brand, Which works out cheaper for me as not enough experiance and don`t want to bugger the board,I will let you know when its back and fitted with results , This will take a little over a week, many thnx

UPDATE :. Well i got the power board back all fixed and installed it ,switched tv on and only had the white V light blinking nowt else ,So i done some research on internet and followed advice which i unplugged the tv then pushed in power and volume up and held them in,then got the wife to plug tv back in while i still held both buttons in,once plugged in live i held them while tv led still flashed This lasted about 30 seconds then Wallahh TV came on and i then done a retune of the freeview channels and changed the setting to quickstart.Now on the night i can turn off tv onto standby and turn back on when i want to and no problems so far ,This has now been approx 3 weeks and alls well . The tv tech tod me he replaced components i mentioned in last comment . Thankyou for the advice @oldturkey03 as the pic u sent me here i got to the 3rd stage with no voltages ,which made my mind up about getting psu fixed .
