I have a TV that has no image or sound. It gives a blink code of 1 short, 3 long. The service manual says: Initial communication from the main CPU is not
received. (Request for the monitor model No. is not received.) → Communication line failure or main CPU start-up failure.
1) Is there any troubleshooting I can do to possibly replace a single component or check the cables before ordering a new main board? (visually, the components look fine)
2) Does anyone know where I can find the files to update the software of a used board to fit my model (there are 6 other models that use the same board)?
