Kèk nan pwoblèm ki pi komen yo avèk ekran ekspozisyon ki ap dirije: tablo Inite parèt nan uit oswa sèz ranje, kolòn, oswa pwen sèl yo pa limen, long, oswa fè nwa. Vizite enspekte broch modil yo ak plon ki koresponn ak fay la pou sikui yo, echèk soudi, ak sikwi louvri. Si wi ou non liy lan koneksyon komen ant anwo a ak pi ba ak modil yo kite ak dwa nan chak selil (se tablo a inite divize an de selil) nòmal (mete multimeter nan fen a bag, mezire opinyon an liy nan modil la ak plon an nan chak opinyon kontwòl). Modil la move. Si ou pa, li ka elimine lè l sèvi avèk yon fil mens pito.

Some of the most common problems with Led Display Screens: Unit boards appear at eight or sixteen rows, columns, or single points are not lit, long, or dark. Visually inspect the module pins and leads corresponding to the fault for short circuits, solder failures, and open circuits. Whether the common connection line between the upper and lower and left and right modules of each cell (the unit board is divided into two cells) is normal (set the multimeter to the ring end, measure the line input of the module and the lead of each control input). The module is bad. If not, it can be eliminated by using a thin wire instead.
