Check the Damper itself
After reset the unit, take steps to PCB as follows for temperature compensation.
1.In the case of 6871JB1431 ( by July 2007)
:Compensate with replacing RCR1
Enter the TEST 2 MODE Does not
No
Checking Damper itself Is the resistance Values between (1) & (4),
(2) & (3) like as below?
(1)BL
(2)YL
Yes
No
(1)RD
(2)WH
Check the Damper itself
Replace

2.In the case of EBR34917102 (from Aug 2007)
:Compensate with Jump wire cutting
JUMP WIRE | Temp. Compensation |
JCR3 | - 1.0 deg |

Resistance of Damper
Test Point | Ressult |
(1)to (4) 373 ~456 ‰
(2)to (3) 373 ~456 ‰
Yes
JCR4 | - 1.0 deg |
