it would seem your fault would be a dry joint ( a solder point on the circuit board has come loose) the only way to fix this is to have the board taken out turned upside down and find were the dry joint is and re - solder it. if your not aware of electronics then it will have to go into the shop. a dry joint repair should only cost you around $ 40.00 - 60.00 in the mean time sticking a folded peace of cardboard under the tv might work as it puts preasure on the board pushing the solder point against the joint

good luck
