Orimoloye Olumuyiwa  “it hasn’t been coming up no red light “ you will have to check the power board first. Use a multimete and make sure that you have power going to the board and that the fuses etc. are okay. Post some images of your boards with your question so that we cna see what you see. Use this guide Adding images to an existing question for that. The usual way to check an error like this on your TV would be by Symptom • The LEDs on the front panel do not work when connecting the power cord. • The SMPS relay does not work when connecting the power cord. • The unit appears to be dead. Major Checklist The SMPS relay or the LEDs on the front panel does not work when connecting the power cord if the cables are improperly connected or the Main Board or SMPS is not functioning. In this case, check the following: • Check the internal cable connection status inside the unit. • Check the fuses of each part. • Check the output voltages of the SMPS. • Replace the Main Board.
