Hello everyone.
I'm adapting an Innolux V320BJ9-Q02 panel to a Philco PTV32G70RCH. The panel works perfectly, but the image is upside down (180° rotated).
Colors, resolution, and timing are all correct. The only issue is the image orientation.
I have already checked the panel datasheet and couldn't find any FLIP, MIRROR, U/D, or L/R pins. Pin 9 (SELLVDS) only switches between VESA and JEIDA LVDS mapping, so it doesn't affect image orientation.
I'm also investigating the panel EEPROM and the I²C lines used for Auto-VCOM (C_SCL and C_SDA), considering the possibility that image orientation is defined by EEPROM data, strap resistors, or an undocumented controller configuration.
Has anyone worked with the V320BJ9 series or found a hardware/firmware solution for upside-down image issues on Innolux panels?
Any information about EEPROM dumps, strap resistors, hidden FLIP/MIRROR settings, or driver ICs would be greatly appreciated.
Thank you!
AI: Can you provide the exact mainboard/scaler board model used in the Philco PTV32G70RCH, and have you checked the service menu for any Panel Type, Mirror, Flip, U/D, L/R, or image rotation options?
The mainboard model is JUC7.820.00261938. I checked both the regular and service menus and could not find any options related to Panel Type, Mirror, Flip, U/D, L/R, LVDS orientation, or image rotation.
The entire image is upside down, including the OSD and service menu. Other than the 180° rotation, everything works correctly (colors, resolution, timing, and backlight are normal).
AI: What was the original panel model from the Philco TV, and can you share how the LVDS/adaptation wiring was done between the mainboard and the Innolux V320BJ9-Q02?
The original panel model is ST3151A08-2. The adaptation was done using the original LVDS connector without any modifications to the wiring. The V320BJ9-Q02 is electrically compatible enough to produce a perfect image, with the only issue being the upside-down orientation.
According to the V320BJ9-Q02 datasheet, Pin 9 (SELLVDS) only switches between VESA and JEIDA LVDS mapping and does not affect image orientation. I could not find any documented FLIP, MIRROR, U/D, or L/R pins in the datasheet.
At this point, I suspect that the image orientation may be defined by the panel's EEPROM data, strap resistors, or undocumented initialization commands sent to the panel during startup.
