Question about Samsung TXR3079 TV
I assume by a blue line you are seeing a seeing a single line left to right across the screen. If this is the case it is a failure in the vertical deflection circuitry. There is no simple repair as a part or parts have failed. In the event of a "power surge" there could be a number of components affected. The unit would really need to be diagnosed by a competent technician. I have worked on many of this model and they are certainly repairable, but probably need two people to move it as they are very heavy as you know. I would get an estimate on the repair and make a decision based on that.
