  If the warning indicator light on your Hisense Projector is flashing twice, it could be due to a few reasons. A foreign object might be jamming the fan, causing it to slow down or stop. Try cleaning the fan. Alternatively, the fan itself might be broken, in which case it will need to be replaced. Finally, there may be a poor fan transmission. If the fan is directly connected to the display board, replace the display board. If there is a poor replacement of the display board/fan adapter board, replace the optical engine fan.

  If the warning indicator light on your Hisense Projector flashes 3 times, the issue might stem from several components. First, check the FFC between the display board and the DMD board; it may be poorly connected or faulty, and reinserting or replacing it might solve the problem. Second, the DMD part might not be correctly installed, or the DMD or DMD board might have failed; try reassembling the DMD or replacing the DMD or DMD board. Finally, the display board itself could be failing, requiring a replacement.

  If the warning indicator light on your Hisense Projector is flashing once, it could indicate that the NTC temperature exceeds the protection temperature. Try removing any shield or reducing the ambient temperature. Alternatively, there may be an NTC failure or poor plug-in. In this case, shutdown cooling (25 degrees), the measurement value is about 10K, then NTC has no problem, if the resistance value is too large or too small (obvious open circuit or short circuit), NTC is bad, replace NTC resistance.

  If the warning indicator light flashes 4 times on your Hisense Projector, begin by reinserting or replacing the cable. If this doesn't resolve the issue, the display board or the mainboard might be faulty. In such cases, replace the display board or replace the mainboard. Further investigation may be required if these steps do not solve the problem.

  If the warning indicator light on your Hisense Projector flashes six times, it could be due to a failure of the display board leading to abnormal color wheel feedback. In this case, you should replace the display board. Another possibility is that the color wheel itself is poor, requiring you to replace the optical engine.
