Regarding to about part no : 8261704300 (O-ring), Due to THS tested the continuous test about lamp "NG" then we checked sample and found oil into the lamp.
And we found that after the lamp have a height temperature it effect from O-ring discharge oil into the lamp.
This problem occurs because the O-ring unprocessed oven before use. So THS would like to add oven process for this part.
Please check below for support on this.
