SELF CHECK DISPLAY
EXPLANATIONS
- For X-ray protection, B1 over-current protection and low B short protection, the power of the TV is turned off if NG is detected.
- Immediately after the power is turned off, POWER LED will be turning on and off. When the power is turned off, you cannot turn the power on again until the AC plug is taken out and put in again.
- The latest failure is stored on the record at the end. The failure record for each check item is counted to the number of 9 at the maximum, When more than 9 failures are stored on the record, the counter remains stopped at 9.
- SYNC is neither counted nor stored in memory.
- Because of the timing of Vcc start-up and shut-down of the IC connecting to the I2C bus during which the power is turned on and off, the operation may be interpreted as an error. In order to avoid the misinterpretation, the self-check functions should be started at about 3 seconds after the power is turned on.
