I have a Sharp LC-60E79U with the blinking light error (Power and OPC blink 2 times together then OPC blinks 1 time. I read the previous thread on Sharp lc60e79u (https://www.badcaps.net/forum/showth...t=66913&page=3) with this same issue, but no resolution was posted.
The service manual indicates this as a “DET_5V (33pin) error (L). 5V is not applied.”
I cannot enter service mode by pressing input and channel down and plugging the unit in to power outlet. However, I can override and enter the diagnostic mode if press channel down and volume up and plug the unit into power outlet, I can get a steady power light but back light does not comes on. Nothing happens when I press power and holding power turn unit off (no power light). Pressing power again returns to the blinking light cycle. I measured voltage in the override state at the power supply and got the following values. I noted that there was no value at pins for S14.3V.
Any advice on next step would be appreciated.
Anzio.
