My tv has progressivly gotten worse. Randomly it would turn itself off. Ramdomly sound but no picture when first turned on. Now the on/off button is the only one working and the tv won't respond to the remote. the volume is stuck at one level and if i press button to increase/decrease the screen flickers and scrambles while pressing the button, but then goes back to same level and screen clears.
Take off the speaker grill, you will see 2 wire plugs, turn the tv on, disconnect both plugs, if it now works with the remote then you need to replace all of the front switches, or leave them unplugged and use the remote, if this doesn't work, you have a bad dm board or signal module which could get very expensive.
