This issue could be caused by a faulty power supply or a malfunctioning component in the TV's circuitry. It is recommended to contact a qualified technician to diagnose and repair the problem.
It's very simple just remove the TV wire connected to your DVD drive then an option will pump up, asking you whether you want to use it, then select yes that's ok, it's done
It could be a lot of things causing the issue, without electronic knowledge it's going to be hard to diagnose, also a 10 plus year old set isn't worth fixing, parts will run more than the set is worth, time for a new set.
The inbuilt speakers are either broken or not working on your TV or the audio amplifiers are missing the supply voltage or the IC audio is not working anymore with your TV or there is an issue with the TV's capacitors.

If the television still won't turn on, turn your TV off at the wall and unplug it from the plug socket. Wait 30 seconds, and then plug it back in and switch it on. This is called a 'soft reset' and should recalibrate the TV
I'd try a different tcon board, if your set doesn't have one replace the main board, if that doesnt fix it chances are really good you have panel issues, and the set isn't repairable
