Shutdown - Temperature LED blinks continously
Refer to figure 39. If the temperature LED blinks continously, the TV is either too hot or
the temperture sensor (IC6904) is defective. The eight pin DIP package (IC6904) is
connected to the microprocessor on the IIC bus. If the bus between this IC and the
n does
microprocessor is broken, the TV will not shut down. Therefore if a shutdow
occur because of IC6904, check for air blockage about the color wheel housing,
unstable supply voltage (3.3V) before replacing the IC. Do not disconnect IC6904.
