now never on again , no red light code

@handymantz if you have no LED red light at all then you are most likely having power supply issues. Let's check a few things.

Start off with the easy things. Disconnect the power cable from your TV. Disconnect all external devices from the TV (everything that is connected to it has to be disconnected.) Now hold the power button depressed for about 30sec-1min.

After that connect one video input source (i.e. DVD player etc.) connect that as a video source. Then reconnect the power to your TV. Now try to turn it on. Let us know what happens.

If nothing happens, you do want to go ahead and disconnect the power etc. once m,ore. Remove the back cover. Check teh power board for obvious damaged components. Look for burned, charred looking or otherwise suspicious looking components on all boards. This series TV has issues with the T-con board. Look at that as well.. Take some good pictures of your boards etc. Those will have to be well focused and large enough to be zoomed in by us.

Now use a multimeter and measure the fuses on the power board for continuity. No continuity, damaged fuse= replace. We do not know your skill level so we want to be careful but if you are okay with testing live high voltage circuits (like your household voltages), go ahead and see if your power supply receives any incoming voltage.

We can show and suggest more once we know what this all looks like. Post your pictures with your Question. That way we can see what you see
