It can be frustrating when this happens, unfortunately we have found this particular fault to be uneconomical to have repaired, with the screen being the main component. The costs can really mount up to the price of a new TV. We offer a wide range of TV repairs but this one can leave us feeling dubious, on intervening on such faults like this. At times some customers have requested insurance reports, having claimed through there home insurance. We can offer this service, please contact us if you would like more information we will be happy to help.
