Possible reasons why the Sharp LC-60C46U unit will not stay on include:

1. Firmware glitch – A reset by unplugging the unit for a few minutes may help, but if that does not work, the issue may persist due to internal software problems.

2. Power supply failure – The power supply unit (RDENCA184WJQZ) may be faulty and not providing stable power.

3. Overheating – Inadequate ventilation or heat buildup near the top vents can cause the unit to shut down to prevent damage.

4. Faulty main or terminal boards – Components like the MAIN Unit (DUNTKD934FM07) or TERMINAL Unit (DUNTKD935FM07) may be defective.

5. Physical or electrical damage – Internal components or connections could be damaged due to age or external factors.
