FE-2 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-2 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. Each time the software detects an error it is stored within the NVM. See Table 2.

To connect a VCR, please refer to the section "Connecting the aerial and VCR" of this instruction manual. We recommend you connect your VCR using a scart lead. If you do not have a scart lead, tune in the VCR test signal to the TV programme number "0" by using the "Manual Programme Preset" option. (for details of how to manually programme these presets, see page 14, step a). Refer to your VCR instruction manual to find out how to find the output channel of your VCR.
Connecting a VCR that supports SmartLink:
For Mono Equipment Connect the phono plug to the L/G/S/I socket on the front of the TV and select 3 input signal using the instructions above. Finally, refer to the "Sound Adjustment" section of this manual and select "Dual Sound" "A" on the sound menu screen (see page 11).
SmartLink is a direct link between the TV set and the VCR. For more information on SmartLink, please refer to the instruction manual of your VCR. If you use a VCR that supports SmartLink, please connect the VCR by using a Scart lead to the Scart :2/q D.
If you have connected a decoder to the Scart :2/q or through a VCR connected to this Scart:
Select the "Manual Programme Preset" option in the "Set Up" menu and after entering in the "Decoder**" option, select "On" (by using or ). Repeat this option for each scrambling signal.
**This option is only available depending on the country you have selected in the "Language/Country" menu.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET BOTTOM PLATES.
For safety reasons, on no account should the plates be removed and not refitted after servicing. (2) REFITTING THE PLATES Because the plates differ in size it is important that the correct plates are refitted in their original location.
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of the A Board printed wiring board, the bottom plates fitted to the main chassis bracket require to be removed. This is performed by cutting the gates with a sharp wire cutter at the locations indicated by the arrows.
Please note that the plates need to be rotated 180 degrees from their cut position to allow the tabs to be fitted into their catch positions.
Note : There are 2 plates fitted to the main bracket. Only remove the necessary plate to gain access to the printed wiring board.

SECTION 3 SET-UP ADJUSTMENTS
· · ·
When complete readjustment is necessary or a new picture tube is installed, carry out the following adjustments. Unless there are specific instructions to the contrary, carry out these adjustments with the rated power supply. Unless there are specific instructions to the contrary, set the controls and switches to the following settings : .................... 80% [or remote control normal] 50%
Carry out the adjustments in the following order : 3-1. Beam Landing. 3-2. Convergence. 3-3. Focus. 3-4. White Balance. Note : Test equipment required. 1. Color bar/pattern generator. 2. Degausser. 3. Oscilloscope. 4. Digital multimeter.

1. 2. 3. Input an all white signal from the pattern generator. Set the Contrast and Brightness to normal. Set the pattern generator raster signal to Red. Move the deflection yoke forward and adjust with the purity control so that the Red is at the centre and the Blue and Green take up equally sized areas on each side of the screen. [See Fig.3-1 - 3-3]. Move the deflection yoke backwards and adjust so that the entire screen becomes Red. [See Fig.3-1] Switch the raster signal to Blue, then to Green and verify the condition. When the position of the deflection yoke has been determined, fasten the deflection yoke with the screws. If the beam does not land correctly in all the corners, use a magnet to correct it. [See Fig.3-4]
