•

P201 (

AC Should not be applied at any time while adding jumpers or

may occur.

a) When AC is applied, the SMPS “MUST” be producing

STBY 3.5V on pins 9, 10, 11 or 12 of P201.

If 3.5V Standby is not being generated, the SMPS is defective
and must be replaced. There is no need to continue with the
next test.
But, make sure AC is arriving at the connector SK101.

(b) Unplug P502 on the Main Board to make insertion of the Jumpers easier.

Use P502 Side to insert resistors

TEST 1:

(1) Add a jumper between (3.5V STBY) pin 7, 8, 9 or 10 and Pin 1 (PWR_ON).

Apply AC. This will turn on the power supply, relay will click.

a) Check that the 24V (24.41V) and 12V power supplies are turned on,

• P201 (12V pins 17, 19 and 21)

• P202 (36V pins 1 and 12) AND P203 (pins 1 and 13)

FRONT (IR, INTELLIGENT SENSOR and POWER LED) SECTION

The IR pulses

(2V

are sent to the

Main board and on to the Microprocessor (

IC602)

via pin 16

.

EEPROM_SCL and EEPROM_SDA arriving on connector P901 pins 1 and 2 on the Main board

The Intelligent Sensor and IR board (located on the bottom left as viewed from the rear) contains the IR
(Infrared Remote Sensor) and the Intelligent Sensor. This board also has the Soft Touch Key Board.

The IR board receives it operating B+ pin 6 from the Main P901 (STBY 3.5V).

The IR (Infrared) remote receiver can be measured (1.48V) at pin 9 of connector P901 on the Main board in
Stand-By. During run pin 9 reads (1.45V).

The Front Power LEDs are controlled by different Clock and Data lines which communicate with the LED
Driver IC U1 on the IR board. These clock and data lines are from the Main board P901 pins 14 and 15 which
are only active when the Power is turned on or off.

The Key board is routed from the IR board Key 1 (pin 4) and Key 2 (pin 5). Arriving at P901 on the Main
Board, then to the Microprocessor 25 and 26 lines.

The Intelligent Sensor communicates with the Micro Processor IC602 pins 3 & 4 via clock and data lines

The Intelligent Sensor circuit receives it’s operational voltage when the set turns on via pin 11
(3.3V_Normal).
