Turn on the power while keeping either KEY4 (pin (81) of the microprocessor) or KEY5 (pin (82) of the
microprocessor) at "L".

3-1. Basic operation
• Tune in with the CH UP/DOWN keys or the direct channel select key.
• Select an item to be adjusted with the cursor UP/DOWN keys.

(When the cursor DOWN key is pushed at the bottom, it moves to the top on the next page, and when the cursor
UP key is pushed at the top, it moves to the bottom on the previous page.)

• Adjust the selected item with the VOL UP/DOWN keys or the cursor LEFT/RIGHT keys.
• When the menu key is pushed, the next item appears. (When the key is pushed at the bottom, the top on the next

page appears.)

• When the manual memory key is pushed, the top item reappears. (When the key is pushed at the top, the top

on the previous page appears.)

• When the auto preset key is pushed, the top on the next page appears.
3-2. Moving through the layers
• On the third page, when the ENTER key is pushed at any item other than I

2

C DATA, the setting page of the item

appears.

• To quit the setting page, push the previous-page key.
3-3. Adjusting the address display items
• At the items OSD COLOR, NTSC and CARD on the G/A page, or at the item EDGE ENHANCEMENT on the

S2300 page, when the VOL UP/DOWN keys or the cursor RIGHT/LEFT keys are pushed, the register select mode
appears. (The cursor moves to the first address.)

• In the register select mode, the cursor moves up and down with the CH UP/DOWN keys, and moves left and right

with the VOL UP/DOWN keys or the cursor LEFT/RIGHT keys. Select an address to be adjusted and push the
direct channel select key "12". This procedure moves the cursor to the right-side value for the address. Adjust
the setting with the VOL UP/DOWN keys or the cursor LEFT/RIGHT keys. Push the direct channel select key "12"
with the cursor at the right-side value, and the register select mode appears again. Pushing the cursor UP/DOWN
keys, the menu key or the like leads to the other item.

5-1. Adjusting the common bias
       1) Make the non-signal state in the video input mode.

       2) Fit the designated tool at the center of the screen.

       3) Observe the output from the tool with the oscilloscope.

       4) Adjust the "COM BIAS" setting on Page 2 of the adjust process to minimize the wave's peak-peak level.
5-2. Adjusting the TAMP
       1) Receive the upper left of 75% white half colour bar signal.

       2) If the reading of "YDATA" on Page 2 of the adjust process is not within the range in the table below, adjust

the "PAL TAMP" setting on the same page to bring the "YDATA" setting in the range below.

~

Keep in mind that the setting may vary from model to model.

       3) Pushing the TAMP direct key finishes the "PAL TAMP" adjustment. Now the setting will be automatically

copied to "SECAM TAMP".

7-1. Functional description

This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety
when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed,
the followings occur.

1

The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front
side of TV turns from green to red.)

2

If the situation 

1

 happens 5 times sequentially, television can not be turned ON. (The power LED remains

red.)

7-2. Countermeasures
7-2-1. Check when turning OFF the lamp error detection

When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment
process with the power LED red. Entering the adjustment process turns OFF the error detection and turns
ON TV.
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" on line 3, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.

7-2-2. Resetting of the lamp error count

After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO
RESET" on line 3, page 1 of the adjustment process and set the number to 0 using the volume button.

8-1. Product outline

SHARP has adopted its original "ASV *2 method low-reflection black TFT flat panel" that can reproduce the
high-contrast images with firm black even in bright rooms. "QS technology" *1 reduces residual images even
for quick-moving subjects to realize eye-friendly images, and "I/P conversion for 3-D motions" suppresses
roughness and flickering. They help you watch the high-contrast and clear images from any angles.
Furthermore, this product is equipped with "PC card slot" to record TV programs on memory cards, and to
show the still images taken with digital cameras on the large screen of an LCD TV with memory cards*.
This model has new design that has side-speakers designed by Toshiyuki Kita, a world-known industrial
designer. The speakers are punching metal-processed, so they have a style showing quality sound capabilities.
The screen properties are, needless to say, much superior to CRT TV sets: low power consumption, long life
backlight, and other power-saving features, as well as reduced flickering.
* QS --> only for LC-20B5E (not available on LC-15B5E)
   <CARD FUNCTIONS>

(1) Enjoying recorded TV programs

To record the program you are watching, all you need is just push the record button. Supporting the hard
disc PC cards newly realizes long-time recording. There are lots of recording functions*, including "Trace
Recording" (Going back to record to a few seconds before starting recording), "Reserved Recording" (Up
to 8 programs programmable a month) and "Easy Recording" (Finish time presettable during recording),
and you can enjoy the recorded programs on full screen.
* The video record system is MPEG-4. Smooth video with 25 frames/sec is realized.
(SD memory cards, Multimedia cards, Compact flashes, Smart media, Memory sticks, xD picture cards
and Micro drive are supported. For use, the PC card adapter specific for each memory card is necessary.
Names of memory cards are trademark.)

• 

Video Recording/Playing functions

One scene in the TV program you are watching can be recorded on memory cards. The recorded video
can be readily reproduced on demand. The Trace Recording function records from a few seconds before,
so you need not worry about delaying the use of the remote controller. Three recording modes (SP/LP/
EP) are available for your applications.

* Record time is variable for the TV reception condition and the video contents.
* Ground-based broadcasting and external input (except for SCART RGB) that are not copy-protected can

be recorded.

* If the file capacity is over 4 GB, or the record time is longer than 12 hours, recording/playing is impossible.

• 

Still-Picture Recording/Playing functions

1) One scene in a TV program can be recorded on memory cards as a still image.

• 

You can readily record text information that you have made a memo until now.

* The number of images is variable for the TV reception condition and the image contents.

2) Enjoying still images taken with digital cameras

With memory cards and on the large screen of an LCD TV, you can readily show still images captured
with digital cameras*.

* Only JPEG still images that were recorded to fit the standard (Design rule for Camera File system: DCF)

by Japan Electronics and Information Technology Industries Association Corp are playable.

* The number of files displayable is up to 1,024, including video and still images.
