four blinking red lights on standby also I have replaced the and lamp and surge protector.

@ddugan the 4 times blink error is usually a Temp or a Fan error. For probable causes you need to check

  • Fan1-4 Power is not supplied. (GI board)
  • Fan connector is not seated securely.
  • Fan caught wires or harnesses.
  • Internal temperature is too high.
  • IIC-E line connector(H4 board) is not seated properly. Try to see if you can get into the Self Diagnosis Screen. Unplug your set for a few minutes. Plug it back in. In standby mode, press the buttons on the Remote Commander sequentially, in rapid succession as shown below: Display==> Channel 5==>Sound Volume (-)==>Power Let us know what your diagnostic screen displays.
