Modern LED televisions contain high-voltage components that can hold a lethal charge even after the TV is unplugged. sharp lc-40le185m service manual
One or more LED bulbs in the backlight strips have failed.
Sharp televisions utilize the front LED indicator to communicate error codes through a series of flashes (e.g., two red flashes followed by one green flash).
Check the output voltage at the LED backlight connector on the PSU during power-up. If the voltage spikes high and then drops immediately, the PSU protection circuit is tripping due to an open circuit in the panel.
: Unplug the TV, hold the power button on the unit (not the remote) for 15–30 seconds to clear residual charge, wait 2 minutes, and plug it back in. Some common issues with the Sharp LC-40LE185M include:
