SERVICE MANUAL
SHARP CORPORATION

SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
As for the places which need special attentions,
they are indicated with the labels or seals on the
cabinet, chassis and parts. Make sure to keep the
indications and notices in the operation manual.
3. USE THE DESIGNATED PARTS
2. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an
electric shock while the electric current is
flowing.
The parts in this equipment have the specific
characters of incombustibility and withstand
voltage for safety. Therefore, the part which is
replaced should be used the part which has
the same character.
Especially as to the important parts for safety
which is indicated in the circuit diagram or the
table of parts as a mark, the designated
parts must be used.
5. PUT PARTS AND WIRES IN THE
ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.
PERFORM A SAFETY CHECK AFTER
SERVICING
6.
Confirm that the screws, parts and wiring which
were removed in order to service are put in the
original positions, or whether there are the
portions which are deteriorated around the
serviced places serviced or not. Check the
insulation between the antenna terminal or
external metal and the AC cord plug blades.
And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
1.
2.
3.
4.
Unplug the plug from the AC outlet.
Remove the antenna terminal on TV and turn
on the TV.
Insulation resistance between the cord plug
terminals and the eternal exposure metal
[Note 2] should be more than 1M ohm by
using the 500V insulation resistance meter
[Note 1].
If the insulation resistance is less than 1M
ohm, the inspection repair should be
required.
[Note 1]
If you have not the 500V insulation
resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone jack
A1-1
4. BE CAREFUL WITH THE
LCD PANEL
Avoid a shock to the panel while servicing.
Take enough care to deal with it.
When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contact
section of the heat sink. Before applying new silicon grease, remove all the old silicon grease.
(Old grease may cause damage to the IC and Transistor).
IMPORTANT
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be
found at the end of the SERIAL NUMBER.
2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.

PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.
(Please refer to figures.)
Caution:
Pb free solder has a higher melting point than standard solder;
Typically the melting point is 86°F~104°F(30°C~40°C) higher.
Please use a soldering iron with temperature control and adjust it to 650°F ±20°F (350°C ±10°C).
In case of using high temperature soldering iron, please be careful not to heat too long.
Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).
All products with the printed circuit board with PbF printing must be serviced with lead free solder.
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Distinction of PbF PCB:
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.

careful not to break or damage the foil of each IC
leads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.
Blower type IC

Heat the IC leads using a blower type IC desoldering
machine. (Refer to Fig. 2-2.)

Fig. 2-2
NOTE
Do not rotate or move the IC back and forth unit IC
can move back and forth easily after desoldering the
leads completely.
When IC starts moving back and forth easily after
desoldering completely, pickup the corner of the IC
using a tweezers and remove the IC by moving with the
IC desoldering machine. (Refer to Fig. 2-3.)

NOTE
When the IC leads are bent during soldering and/or
repairing, do not repair the bending of leads. If the
bending of leads are repaired, the pattern may be
damaged. So, be always sure to replace the IC in this
case.
Finally, confirm the soldering status on four sides of the
IC using a magnifying glass.
Confirm that no abnormality is found on the soldering
position and installation position of the parts around the
IC. If some abnormality is found, correct by resoldering.

INSTALLATION
Take care of the polarity of new IC and then install the
new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.

Press RIGHT/LEFT button to select DATA. When DATA is selected, it will "blink".
Again, step through the DATA using UP/DOWN button until required DATA value has been selected.
Pressing RIGHT/LEFT button will take you back to ADDRESS for further selection if necessary.
Repeat steps 4 to 6 until all data has been checked.
When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
After the data input, set to the initializing of shipping.
Turn POWER on.
Press both VOL. DOWN button on the set and Channel button (1) on the remote control for more than 2 seconds.
After the finishing of the initializing of shipping, the unit will turn off automatically.
If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to
ensure correct data settings while making reference to INITIAL SETTING TABLE (Attached "INITIAL DATA").
