LED blinks in RED automatically.
A failure part can be expected by the number of times of blink of LED.
When two failures occur, the failure item generated previously is detected.
When failure occurs simultaneously, an item with little number of times of blink is detected.
When two failures occur, the failure item generated previously is detected.
When failure occurs simultaneously, an item with little number of times of blink is detected.

In the following case, POWER LED of Media Receiver Box blinks at a fixed interval in ORANGE
• When the cable which connects between Media Receiver Box and Panel Display has fallen out.
• When the AC code for Panel Display has fallen out.
• When the cable which connects between Media Receiver Box and Panel Display has fallen out.
• When the AC code for Panel Display has fallen out.
• When the cable which connects between Media Receiver Box and Panel Display has fallen out.
• When the AC code for Media Receiver Box has fallen out.
• When the AC code for Media Receiver Box has fallen out.
In the following case, POWER LED of Panel Display blinks at a fixed interval in ORANGE
every about 0.3s
about 3s

The example which judges whether it is failure
• POWER LED of Media Receiver Box: Blink 9 times in RED, and of Panel Display blink,
• POWER LED of Media Receiver Box: Blink 9 times in RED, and of Panel Display blink,
and No picture or Power circuit does not work
→ Large possibility that Panel Display is out of order.
• When turn on Media Receiver Box, and NO LED of Box shine
→ Large possibility that Media Receiver
Box is out of order.
• When NO Blue LED of Box shine
→ Large possibility that Media Receiver Box is out of order.
Check SET5V or IIC line on H1 board.
• When turn on Media Receiver Box, and Fan does not work
→ Large possibility that Media Receiver Box is out of order
