Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it.

The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset.

Try this! There should be a power button on the bottom of the panel that has to be depressed for the television to power on. It is the main power supply button and without it there is no power going into the TV.

got same problem the LG sound plate works with bluetoth mode but don't not detect the pioneer tv set..

1. if you have something else that you can test the optical wire on. do that first. dvd player etc... if the test item works, it's the sound bar (or a setting in the sound bar.) 2. check the audio settings on your t.v. make sure it's set to output to optical. 3. replace the wire. if none of these solve the problem, the t.v.'s optical output may be bad.

The main board fault. Contact the authorized service centre for Olevia. Gopakumar Gopalan Google

A few steps to take to narrow down issue:1. With sound all the way off do you hear the buzz?2. If no buzz that way try the rear inputs with a DVD etc to see if same issue.If the buzz is there with no sound (turned all the way down) and via rear inputs you have a transformer (most common area is power supply) that is vibrating hard enough to create the sound or buzz.Only two ways if that is the case to deal with it---replace the board it is coming from (have seen brand new sets with this) or in some cases I have been able to locate the offending part and apply hot glue to it and stop the buzz.SD TECH

Unless it has a hookup for external speakers do not do it---speakers must match inpedance of original speakers, wrong speakers can result in damage to audio circuit of set, cause reduced sound levels etc.A inexpensive surround sound system might be a option......
