What to do if the warning indicator light flashes 4 times on my Hisense C1 Projector?
If the warning indicator light on your Hisense Projector is flashing 4 times, it could be due to a communication failure between the display board and the TV board. Try reinserting or replacing the cable. Alternatively, the display board or the mainboard might have failed, requiring replacement.
What to do if the warning indicator light flashes 3 times on my Hisense C1?
If the warning indicator light on your Hisense Projector is flashing 3 times, it may indicate a DLP system failure. Try reinserting or replacing the FFC. It could also be due to the DMD part not being correctly installed, a DMD failure, or a DMD board failure; try reassembling or replacing the DMD or DMD board. Another potential cause is a display board failure, which would require replacing the display board.
Why is the warning indicator light flashing 2 times on my Hisense C1?
If the warning indicator light on your Hisense Projector is flashing 2 times, it might be because the fan speed is slow or the fan has stopped spinning. Try cleaning the fan. If the fan is broken, you'll need to replace it. A poor fan transmission could also be the issue, in which case the display board should be replaced.
How to fix a Hisense C1 when the warning indicator light flashes 1 time?
If the warning indicator light on your Hisense Projector is flashing once, it could mean that the NTC temperature exceeds the protection temperature. Try removing any shield or reducing the ambient temperature. It could also be due to NTC failure or poor plug-in. If shutdown cooling is at 25 degrees and the measurement value is about 10K, the NTC is likely fine. However, if the resistance value is too large or too small (an obvious open or short circuit), the NTC is bad and needs to be replaced.
