OS-2S 94v-0 T-Con Board Repair Manual and Voltage Details

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
