The red indicator will continue to flash in intervals of three
blinks at a time until the lamp door or the lamp is placed
correctly. When the lamp door or the lamp is securely
attached, the TV will turn on with green indicator.
The projection lamp has burned out. Replace it with new
one (see page 86).
When one of the timers is set, the indicator will remain lit
(will not flash) even when the TV is turned off.
POWER
Projection Lamp
Your T V u ses a projection lamp as its light source. As with any lamp, it has
lifespan and needs to be replaced when the Lamp indicator flashes or the
screen becomes darker. Note the following:
After turning on your TV, it may take a while (1 minute or less) before
the picture appears.
When the projection lamp wears out, the screen goes dark. Replace the
lamp with a new Sony XL-2400 replacement lamp (not supplied).
The light emitted from the lamp is quite bright when your TV i s in
use. To avoid eye discomfort or injury, do not look into the light
housing when the power is on.

The projection lamp, which illuminates the picture, has a limited life.
If the screen becomes dark, the color looks unusual, or the LAMP indicator
on the front of the TV flashes, it is time to replace the lamp with a new one
(not supplied).
WARNING
Electric appliances can cause fire or high temperature, resulting in
injury or death. Be sure to follow the instructions below.
Use a Sony XL-2400 replacement lamp (not supplied) for replacement.
Use of any other lamp may damage the TV.
Do not remove the lamp for any purpose other than replacement. Doing
so may cause injury or fire.
Do not put flammable materials and metal objects inside the lamp
receptacle of the TV after removing the lamp. Doing so may cause fire
or electrical shock. Do not touch the lamp receptable once the lamp has
been removed.
When the lamp eventually burns out, you may hear a noticeable pop
sound. This is normal and it is inherent to this type of lamp.
In rare instances, the bulb may pop inside the lamp unit, but the lamp
unit is designed to contain all of the broken glass pieces inside the lamp
unit.
The lamps contain mercury. For proper disposal of the used lamps,
follow and observe the local ordinances. See page 89.
How to Replace the
Lamp
1
Turn off the power on the main unit. Wait several minutes, then unplug
the power cord.
(The cooling fan will continue to operate for about two minutes after
turning the power off.)
2
Wait at least 30 minutes after unplugging the power cord to allow the
lamp to cool down before replacing it. To avoid being burned, do not
touch the lamp receptable once the lamp has been removed.
3
Take th e new lamp out of the box.
Do not touch the glass portion of the new lamp.
Do not shake the lamp. Vi bration can damage the lamp or
shorten its life.
Avoid touching the front glass of a new lamp or the glass of
the lamp receptacle. Th is may reduce picture quality or lamp
life.

SAFETY CHECK-OUT
( US model only )
KDF-E42A10/E50A10
After correcting the original service problem, perfom the follow-
ing safety checks before releasing the set to the customer:
l. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
5. Look for parts which, through functioning, show obvious
signs of deterioration. Point them out to the customer and
recom mend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the condition of the monopole antenna (if any). Make
sure the end is not broken off, and has the plastic cap on it.
Point out the danger of impalement on a broken antenna to
the customer, and recommend the antenna’s replacement.
8. Check the B+ and HV to see they are at the values specified.
Make sure your instruments are accurate;be suspicious of
your HV meter if sets always have low HV.
9. Check the antenna temminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5mA (500 microampers) . Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
usc these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. NearIy all battery operated digital multimeters that have a 2V AC range
are suitable. (See Fig. A)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground;the cover-plate retaining screw on most AC outlet boxes is also at earth ground. If
the retaining screw is to be used as your earth-ground, verify that it
is at ground by measuring the resistance between it and a coldwater pipe with an ohmmeter. The reading should be zero ohms. If
a cold-water pipe is not accessible, connect a 60-l00 watts trouble
light (not a neon lamp) between the hot side of the receptacle and
the retaining screw. Try both slots, if necessary, to locate the hot
side of the line, the lamp should light at normal brilliance if the
screw is at ground potential. (See Fig. B)

SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
-This device includes a self-diagnosis function.
-Incaseofabnormalities, the POWER/STANDBY indicator automatically blinks. It is
possible to predict the abnormality location by the number of blinks. The Instruction
Manual describes blinking of the POWER/STANDBY indicator.
-Ifthe symptom is not reproduced sometimes in case of a malfunction, there is recording of
whether a malfunction was generated or not. Operate the remote command to confirm the
matter on the screen and to predict the location of the abnormality.
2. Diagnosis Items and Prediction of Malfunction Location
-When a malfunction occurs the POWER/STANDBY indicator only blinks for one of the
following diagnosis items. In case of two or more malfunctions, the item which first
occurred blinks. If the malfunctions occurred simultaneously, the item with the lowe
blink count blinks first.
-The screen display displays the results regarding all the diagnosis items listed below.
Thedisplay "0" means that no malfunctions occurred.
