Question about Sharp AQUOS LC-32D43U 32 in. LCD Television
This unit probably has a bad power supply. It may also be shutting down because if this unit has recorded 5 lamp errors it goes into shut down. To eliminate lamp errors you can force the unit on in the service mode and look for lamp errors. To do this, you unplug the unit, and while depressing the volume up and channel down buttons at the same time, plug the unit in. Hold for 1 second and release. The unit will then power on and a small k should appear on the screen. If this does not happen then there is definately an internal failure that will require a sharp auth. service center. If the unit does come on with the k, use the remote and press the channel up button. This will produce a menu on the screen and you will note on line will indicate lamp errors. On the right side of that line will show the # of lamp errors. If it reads 0, lamp errors are not the issue, however if it reads 5, you can highlight that line by using the channel down button. Then use the curser right arrow to select the error and then again to reset them. Once the lamp errors have been reset to 0, unplug the unit and wait at least 25 seconds before plugging in. The unit will now power up normally and this may cure the problem for good. If this process corrects the problem and it occurs some time later or right away that will be an indication that either the unit has bad backlights or inverter has failed and will again require service.
