my sony tv KLV-26CX320 is showing red light on, not turning on power via remote and back side of the tv power botton
Gvk Sharath sound slike a power board issue. You did not tell us if the red LED blinks or if it stays on. Ultimately, I’d suggest to remove the back of the TV and take a look at the boards. Check for bulging, leaking capacitors. Post some picture of what your boards look like with your question so that we may see what you see. Use this guide for that
