T-CON Check Spreadsheet

Re: T-CON Check Spreadsheet

Excel isn't hard, it's just equations and overly-complicated IF-equations (just click any cell to view the formula!) I did it in openoffice because I don't have a copy of Excel.

The voltage has to increase OR decrease, in other words, differential voltage from point to point, the sign of the number needs to stay the same. Also, the symmetry test mirrors the voltages around VCOM (AVDD/2 or mid point average of gamma voltages) and sees if they match up. The symmetry test is an additional test, both should be done. It's a lot harder to do in your head. If either of these fail, the result is a guaranteed fail.

Note -- the Detailed Results tab is more of an internal debug tab -- you should look at Summary for overall conclusion.

New version coming soon with improvements and bug fixes.

how about this flickering screen with horizontal line

INPUT 12.47V
VGH 30.34V
VGL -9.50V
AVDD 16.30V
VCOM 6.90V
VSS -9.16V
WP INV 3.39V

Flickering/double images and horizontal lines are panel problems but may be repaired with a workaround using the tape cutoff method.
