I have a sony tv(KP-61HS10) with the symptoms listed in the partial
below. I would like to repair it myself, however I have only been able
to find this small part of the service bulletin.

Can someone please share the rest of it with me, point me to the write
place, or tell me the change/add/remove for the bulletin.


Service Bulletin NO: PTV-00-018R2
(1/4)
SUBJECT: AKB Error When First Turned ON
DATE: August 2001 MODEL (S): KP-53XBR300, KP-53HS10, KP-61HS10,
KP-61XBR300
Symptom: When the unit is first turned on from cold start the LED
flashes 5 times at first power-ON,
and no picture is received. If turned ON/Off then ON again picture is
present. Unit
will play the rest of the day without any problem.
Solution: If the customer should complain of the symptom above please
perform the following circuit
changes to the BD Board.
Note 1: Some BD boards had countermeasures applied at the factory.
These boards do not
need to be reworked in the field. See illustrations 1 through 3 for
identifying the boards
that have had countermeasures applied at the factory.

Subject: AKB Error When First Turned ON Date: August 1, 2001
Symptom:
(2311) When the unit is first turned on from cold start the LED flashes
5 times at first power-
ON, and no picture is received. If turned OFF and then ON again picture
is present.
Unit will play the rest of the day without any problem.
Solution: If the customer should complain of the symptom above please
perform the following
circuit changes to the BD Board.
Note 1: Some BD boards had countermeasures applied at the factory.
These
boards do not need to be reworked in the field. See illustrations 1
through 3 for
identifying the boards that have had countermeasures applied at the
factory.

Illustration 1
Carefully peel up the coper tape
on the side edge of the board.
Illustration 2
Lift up the shield from the board, using the
long copper tape as a hinge.
Illustration 3
Factory-reworked boards have a 10K chip
resistor mounted near R1924; no further
rework is necessary.
TV Products Service Bulletin No. 484R2
Note 2: The specific procedure depends on whether or not the original
service
bulletin had been performed previously.
=B7 If R1709 and R1713 are both mounted on the board and are 470 ohms,
the
original bulletin was not performed previously.
=B7 If only R1713 is mounted and is 100 ohms, and R1709 is not mounted,
the
original bulletin was performed previously.
=B7 New BD boards received from WRPC-AS must also be checked to see if
the
original bulletin was performed previously.
Procedure for BD boards that have not had the original bulletin
performed.
1- Change R1709 and R1713 from 470 ohm to 1K ohm.
2- Remove Q1701.
3- Add a 10K resistor to the A-side of the BD board near C1741 as shown
in the
illustration.
4- Check the solder joints of all pins on IC1718 and touch up if
necessary.
