My TV started loosing picture but was keeping sound and then it got to where it would not turn on. I replaced the T Con Board and it started working correctly immediately. Unfortunately, it has started loosing picture again. I am wondering if there is something tearing the T Con Board up. What else should I replace and if I do need to replace something else do I need to replace the T Con Board again.
Main board feeds the t con board. However try the flash light test on set because it might just be the inverter board that powers the backlighting.
