Content: OS-2S 94v-0 T-Con Board and V320BJ8-Q01 Innolux LCD TV Panel Repair Tutorial.
This edition includes OS-2S 94v-0 T-Con board test points voltages, CKV point-out review, and T-Con board repair guidelines. This board is installed in an InnoLux LCD TV panel, model number V320BJ8-Q01. The gate driver circuits of LCD panels of most models manufactured by InnoLux are COG or chip-on-glass technology, so in many cases, they are not repairable.
However, the OS-2S 94v-0 T-Con board is installed on V320BJ8-Q01 panels, combining gate COF and source COF in one film. The COF has two sets of CKV connections on the right and left side, so these panels are easily repairable and will last longer in most cases. That's why InnoLux should make LCD panels using OS-2S 94v-0 T-Con board technology to avoid our complaints.
Dear friends, In response to many of your requests on YouTube and Facebook, I have published the voltage details of all the OS-2S 94v-0 T-Con board test points in the images below. I have observed that many of you search on Google by typing "OS-2S-94v-0 Datasheet PDF." Although I have not published this here in PDF format, hopefully, you will find almost all the information you need for this T-Con board repair.

OS-2S-94v-0 T-Con Board CKV and All Test Points Voltages
If the V320-Q01 LCD panel does not display the image, the CKV, STV, and BLNK voltages on the OS-2S-94v-0 T-Con board must be checked. So, the exact voltage of all the test points on the board is procached below.
VIN - 12 Volts
VDD_R = 3.33 Volts
VAA = 17.90 Volts
VGL COP = -12.51 Volts
N - 1.13 Volts (All N)
P- 1.12 Volts (All P)
VCM (VCOM) = 7.32 Volts
VDDAM = 7.54 Volts
VGL_AA = -7.54 Volts
VGH_LS = 30.4 Volts
WP (Wright Protection) = 3.34 Volts
SDA (Data) = 3.32 Volts
SCL (Clock) = 3.32 Volts

When the Innolux LCD panel screen goes black or no image or graphics appear, checking the voltages for most TVs shows that the CKV voltages are incorrect. Therefore, check the CKV voltages from the list below. Then, if you need to cut six connections of CKV, you can watch this VIDEO tutorial on YouTube to learn how to do that.
CK1_LS (CKV1) = 1.54 Volts
CK2_LS (CKV2) = 1.54 Volts
CK3_LS (CKV3) = 1.54 Volts
CK4_LS (CKV4) = 1.54 Volts
CK5_LS (CKV5) = 1.54 Volts
CK6_LS (CKV6) = 1.54 Volts
STV_LS = -12.47 Volts
Blank_LS = -12.47 Volts

Right Side CKV STV and Blank Voltages
JPG_R2 (CKV1) = 1.54 Volts
JPG_R3 (CKV2) = 1.54 Volts
JPG_R4 (CKV3) = 1.54 Volts
JPG_R5 (CKV4) = 1.54 Volts
JPG_R6 (CKV5) = 1.54 Volts
JPG_R7 (CKV6) = 1.54 Volts
JPG_R1 (STV) = -12.47 Volts
JPG_R8 (Blank Right) = -12.47 Volts
