Loosen two screws with the supplied wrench.

Pull out the lamp by the handle.

Attach the new lamp.

Fasten two screws tightly.

Attach the lamp cover.

Fasten the screws tightly.

Attach the front panel.

Be careful not to damage the speaker.

Notes

• Do not touch or stain the front glass of the new lamp or the glass of the lamp compartment. If the glass become dirty, the picture quality may deteriorate or the lamp life may shorten.

• Attach the lamp cover firmly. If it is not firmly attached, the power will not turn on.

• When the lamp burns out, a noise is audible. This does not represent a damage.

• Consult your nearest Sony service center to obtain a new lamp.

T roubleshooting

Here are some simple solutions to some problems which may affect the picture and sound.

Problem

No picture (screen is dark), no sound

Poor or no picture (screen is dark), but sound is OK

Poor picture quality when watching an RGB video source Good picture but no sound

No colour for colour programmes

Remote Commander does not function

If you continue to have problems, have your TV serviced by qualified personnel. Never open the casing yourself.

Solution

• Plug in the TV in.

• Press f on the TV (if f indicator is on, press O or a programme number on the Remote Commander).

• Check the aerial connection.

• Check if the selected video source is on.

repeatedly to select .

• Press

• If o is displayed on the screen, press o.

to enter the PICTURE CONTROL menu, select RESET, then

• Press press OK.

• The batteries are weak.

Warning Indicators

When a problem occurs, the indicator flashes as follows. Attempt the solution recommended for the given problem. When a problem occurs while operating the set, the f (standby) indicator flashes first and then warning will be indicated.

– 17 –

Cause

The lamp burns out or the quality of the lamp is deficient.

The cover of the filter or the lamp is removed.

The fan for cooling stops.

Internal heat builds up.

If the lamp flashes in a way not described above, consult your nearest Sony service center.

Indicator flashing patterns

The B indicator flashes twice then A flashes once. Flashing continues in this manner.

The B indicator flashes three times then A flashes once. Flashing continues in this manner.

The B indicator flashes four times then A flashes once. Flashing continues in this manner.

The B indicator flashes five times then A flashes once. Flashing continues in this manner.

Stabilizing the Projection TV

After setting up, secure the projection TV to a wall, etc., with the supplied brackets, for safety purposes.

1 Mount the two supplied brackets with the screws to the upper rear side

of the projection TV.

Bracket (supplied)

2 Pass a strong cord or a chain through each bracket mounted in 1, and

then secure to a wall or a pillar, etc.

AE3 has 3 packages of Analogue data:

1. Last Power memory data. This data is sent

continiously to the corresponding IC’s (TDA1839, SC,

TDA6812) with this data the TV picture/sound

appears.

2. Reset data. By pressing “Reset” in the menu this

data is transfered from Reset Data location to the

Last Power data location in the NVM.

That means the previous Last Power Memory Data is

overwritten by the Reset data last Power memory and

Reset data are now the same.

Additionally the Error Reader can be connected to the service connector to read out the actual errors.

The device check itself is active while the TV set is running out of stand-by mode. The devices are checked by sending an I2C start sequence and if there is no acknowledgement back from the devices it is regarded as an error. Each device is checked three times and if at every attempt there is no reply from the relevant device an error is given. To read the error codes press ‘TT’ followed by 22 on the commander to view the Error Monitor menu.

To reset the error codes in the NVM press ‘TT’ followed by 65 on the remote commander.

3) Add 0 V to TP5211 <RLBS> and 9 V to TP5210 <RHBS> by DC power supply.

4) Adjust the level by RV5205 <R-GAIN> as “0 IRE ~ 100 IRE” on TP5203 <R-sig2> is 1.50 ± 0.02 Vp-p.

7) By RV5204 <R-S, GAIN2> & RV5208 <R-S, BIAS2>, adjust the waveform for TP5204 <R-sig3> to the waveform for TP5203 <R-sig2>. (within ± 0.02 V)

8) Confirm that the waveform for TP5203 <R-sig2> is within standard mentioned.

(7) IC Level Adjustment (G ch)

1) Proceed 4) ~ 8) by the same way as R ch.

2) Proceedure 3) to add external voltage must not be done. As for “related VR” and “output terminal” please refer to the Fig.

(8) IC Level Adjustment (B ch)

1) Proceed 3) ~ 8) by the same way as R ch. As for “related VR” and “output terminal” please refer to the Fig.
