SECTION 1 SELF DIAGNOSIS FUNCTION

1-1. RE-3W SELF DIAGNOSTIC SOFTWARE
The identification of errors within the RE-3W chassis is triggered in one of two ways : - 1: Busy or 2: Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using this method.

1-2. ERROR DETECTION MONITOR
Device acknowledge is used to check IIC errors. Device acknowledge is checked by sending an IIC start sequence during CRT power on. Each device is checked three times, if there is no acknowledge after each attempt, it will be regarded as an error. There are three steps to check for errors. 1. IIC line 0 If all devices except the NVM have errors, IIC line 0 error is displayed. 2. Board check If all devices mounted on one board have errors, board error is displayed. 3. Each device check if IIC line error and board error are not detected then the device with an error is displayed. The detected errors can be displayed as follows: 1. Error Monitor Menu 2. Error Reader

1-2-1. Error Monitor Menu
The error monitor menu is displayed by selecting TT33. The following menu will be displayed:

4-1. SCREEN VOLTAGE ADJUSTMENT (ROUGH ALIGNMENT)
1. Receive the Monoscope signal. 2. Set 50% BRIGHTNESS and minimum PICTURE. 3. Turn the red VR on the focus pack all the way to the left and then gradually turn it to the right until the point where you can see the retrace line. 4. Next gradually turn it to the left to the position where the retrace line disappears.

5. Rotate the green lens and align to obtain the best lens focus at the center area. 6. Rotate the green focus VR on the focus pack and align to obtain the best electrical focus in the top right corner. 7. Perform the same alignment for red and blue lenses and electric focus. 8. Fix lens screw.

6-2-1. Setup for Adjustment 1. Marking
1) At the 4 insides of the screen, locate the middle. Use a tape measure to identify the middle.

5. Adjust "1 V-Size" and "6 H-Size" so that the picture size is within the specification.

SPEC
Input Signal PAL SPCB H SIZE 16.7 ± 0.1 sq.

Overscan Spec. = 7.5%

V SIZE 12.5 ± 0.1 sq.

1 V-Size

6 H-Size

2. Data Setting
1) Set DRC100 (PAL-Wide) mode. 2) Enter the Service menu, and select "Device Register Setting" b "Projector Engine". 3) Press "7" + "-" (READ) buttons on the commander to read the data from NVM. Then all the default data are restored. Note : When you replaced printed circuit boards or devices or CRTs, and when correction is drastically necessary, press "5" + "-" (PJE INITIAL) buttons to initialize the data in the Projector Engine mode. Press " (MUTE)" + "-" buttons on the commander to write the data.

6. Adjust the following items so as to attain the optimum picture. 4 V-Linear

5 S-Corr

8 Pin Amp

6-2-2. Main Deflection Adjustment
The data values are same in all modes, and therefore the adjustment for the DRC100 (PAL-Wide) mode only is performed here. 1. Place the caps on the red and blue lenses so that only the green color is displayed. 2. Enter the PAL SPCB signal to set the DRC100 (PAL) mode. 3. Set the screen format to "Wide". 4.

6-8. AUTO CONVERGENCE ERROR CODE LIST
If an error code is displayed after the set has been fully adjusted, correctly, plese check the following items : position, tilt and sizing. If either of these adjustments are off, even slightli, the auto registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns is being flashed on the screen for the sensor to read. Therefore, auto registration (called auto convergence) cannot operate properly causing an error code to be displayed. In order for this function to operate properly, correct position, tilt and size must be adjusted properly.
