[t1412]

afternoon fella's, just been out 2 look at a bush lcd model number s642f no picture fault, i tested voltages all ok, did notice when moving lvds cables would show osd but no picture if  then you leave to cool down the picture would appear would you say main av board or tcon, and also when i moved lvds cables the tv would switch  off  and back on again and so it could be faulty lvds cables let what you think chaps. thanks for your time
