You should connect your TV to an Active DtH Connection or a Live TV Cable or even to a working DVD/VCD Player etc. and tune it to the frequency of the same and it should start working. If it doesn't, please contact Service Center.

G'Day!
There is a circuit board that needs to be fixed or replaced inside the TV. This isn't something you'd want to try unless you have that type of experience. A local TV repair shop will be able to get the service manual and determine exactly which board is causing the problem. As long as the part needed for the repair is still available from the manufacturer, you won't have any problems other than having to pay for the repair out of pocket if you didn't purchase an extended warranty.

I'm afraid not, this will be a defect within the screen & the only remedy is to have the screen replaced.
