Your main pcb could still have gotten damaged due to the defective caps. The reason you still have audio through the optical is because it is a digital signal only. It is not running through the audio amplifier on the main board. I would suspect either the main pcb or the speakers them self.
Do not keep forcing this unit on - - This particular unit has a VERY commonly known problem and there are at least five tech bulletins from LG explaining this and other symptoms for the failure. In a nutshell there are coils that have to be removed and replaced with a jumper wire. This is not a repair you want to tackle so please get some experienced help for this one. A good technician will look-up the bulletins and educate themselves on the manner of the repair.
Almost all of the symptoms that can happen are intermittent and can be extremely difficult to verify. For this reason make sure to discuss with the technician that he replace all of the coils listed in the bulletin not just the ones causing your particular problem. Here's a list of symptoms that these defective coils cause, taken right from the bulletin:
1. Channels Or Menu Functions Scroll On Their Own 2. Remote Does Not Function 3. Tv Randomly Powers On And Off On Its Own 4. Dead 5. No Backlight
Hope this helps!

The white/yellow/red cables is solely your DVD to TV cable connection, If you play a DVD do you get the DVD picture? It looks as if you do not have the connection from the cable going into your TV input (aerial connector). If this is connected then you have to retune your TV. this is done by the Menu-set up button on the remote.
