I have a 53" Sony KP53S75 big screen projection tv. When I turn it on now, there are multiple colored line that stay on across the screen. It flashes through all three colors and then shuts off. It then will not turn back on until I unplug and plug back in. Then it happens again. Any help would be excellent. Thank you for taking your time to help me out.
Do you have a multimeter, soldering equipment and some knowledge of what to look for? If so someone may be able to give you some tips, otherwise you may as well call a tech to look at it, there's no magic fixes for these things, it requires measuring voltages and isolating the problem to a specific subsystem and then tracking down the defective components.
