Sharp Lc-32le150m Service Manual -

Probe the voltage output at the LED strip connector.

Unplug the TV power cord. Press and hold both the VOL - and INPUT buttons on the physical TV bezel simultaneously. While holding them down, plug the power cord back into the wall outlet. Keep holding the buttons until the screen illuminates or the standby LED blinks erratically. This bypasses corrupted settings and boots the television into its service menu recovery mode.

You can hear audio or see the TV turning on, but the screen is completely black. If you shine a flashlight directly at the screen, you can see the faint picture. Troubleshooting:

| Blink Count | Likely Fault Area | Components to Check | | :--- | :--- | :--- | | | Power Supply or Main 5V rail | IC7001, D7001, F7001 fuse | | 3 Blinks | Backlight / LED Driver | CN7201 connector, LED strips, Q7201 MOSFET | | 4 Blinks | Audio Amplifier | IC3001 (TPA3110), speaker resistance | | 5 Blinks | Mainboard / Firmware | Flash ROM IC, corrupt EEPROM | | Continuous Blink | Panel or T-Con | LVDS cable, T-Con fuse, panel driver IC failure | sharp lc-32le150m service manual

While holding the buttons, plug the TV back into the power outlet.

The LC-32LE150M generally does not support USB user upgrades for major firmware revisions.
