REPAIRING / SERVICING LTF320AP11 LCD PANEL FAULTS

 The following explanations are only for the LTF320AP11 coded panel. It does not work for different panels.


If you do not have enough technical knowledge and experience, do not try it.



PROBLEM -----> There is a problem on the screen as in the picture:


The cause of the problem is that the conductive lines on the right and left sides of the panel that carry the signals on the panel card to the panel cells are damaged by heat. As a workaround, you can add plastic cooler on the defective part as in the picture below.


If the problem persists despite the cooler, cut / disconnect the CKV1, CKVB1, CKV2, CKVB2 and STVP lines one by one. If you find out which signal is causing the problem, join back the other lines you have cut / disconnected.
