Sharp HT-SB60 SOUND BAR HOME THEATER SYSTEM - Circuit Diagram – LED blinking codes
HT-SB60
Sound Bar Home Theater system consisting of HT-SB60 (sound bar system) and
CP-SW60 (active sub-woofer system).
Used ICs: EP92A2E [HDMI] – HT165235 [FL DRIVER] – TAS5504A – TAS5342 [SUB-WOOFER OUTPUT] – CS495314 – M3030RFEGPFP
Abnormal
detection distinction at DEMO indicator (LED_red)
It has a case that need to
Power OFF immediately after detected an abnormal condition without
display any error indication due to safety matter. In such case, a
trouble point can be judged by a distinction indication at DEMO
indicator which current is being supplied during Power off.
Basically, it is decided
to be distinguished which input port of the system microcomputer was
detected or which communication information was detected. Moreover, two
kinds of over-voltage and drop-voltage are decided to be distinguished,
and contents of indication are decided to be changed when it is detected
in the range of the A/D value in the A/D input port, for example the
over-voltage, the normality voltage, the drop-voltage of the power
supply line are being monitored.
DEMO
indicator Distinction Display Format
A
lighting period (or flashing period) and a lights-off period are controlled as
the bottom figure after the abnormal detection and the Power off transition. It
will repeat and control 1 frame of the bottom figure. (A lighting period or
flash period is mentioned on the "H" side.) 1 frame is set up as 2
sec lighting period in every 3 sec or flashing period, repeat m time, and then
the last period only (m+1) should turn off the lights. (To recognize the head
position.)
m
is < 2 m < 10, it can be set up in every model freely as long as
"‘Distinction No.’ and the Abnormal Detection Table” mentioned in two
clauses are protected.
A
flashing period is set to one place only of No. 1 - No. m, and others are
lighting period. The ‘Error Distinction No.’ is made at which part is flashing.
In other words, it is set as the ‘Distinction No.’ by looking at which number
is flashing from the head of 1 frame.
It
can set up freely in every model the repetition period 3sec, the lighting or flash
period 2sec, a flashing periodic 500ms etc. as long as it can be recognized.
It
defines the abnormal detection contents that correspond to the ‘Distinction
No.’ as the bottom table in order to put in together between the models.

It
is desirable to indicate it with small ‘Distinction No.’ when it is being
monitored two and more abnormal detection in one line together using 1 port. In
other words, when it is being monitored by compound 1 input. For example, it is
set to Distinction No. 1 when System Protect and AMP Protect are being monitored in 1
port.
For
this model, abnormal detection (Power Off without error display) as the
following.

As
for subwoofer Abnormal Detection, there are 3 types of detection.
The detection is by simple RED LED flashing indicating Abnormal Status.
The detection is by simple RED LED flashing indicating Abnormal Status.
Repeated
Bus Error è Red

System
Protect è Red

Manual
pairing between the Amplifier and Sub-woofer
After
changing the TX or RX Wireless Modules, the Sound bar and Subwoofer must
establish a link. Set the connection by the following method.
Press
and hold the PAIRING button on the sound bar for more than 3 seconds.
Within 2 minutes, press and hold the PAIRING button on the subwoofer for more than 3 seconds.
Within 2 minutes, press and hold the PAIRING button on the subwoofer for more than 3 seconds.
During
pairing process
On
sound bar : “PAIRING” will blink.
On
subwoofer : indicator will blink in blue.
When
pairing is successful
On
sound bar : “PAIRING” disappears.
On subwoofer :
indicator turns blue.
