Faults and possible reasons
Vertical bar, Vertal gray line, Vertical color line(light or dark forever)
Block Defect :TCP cracking or cracking
Dim or L/D :TCP Sunken
*TCP lead cracking
*ACF bonding short
*Awful environment and something electric enter into LCD
*Mis-align between TCP and Panel
*Panel failure
*TCP failure.
Horizontal bar, Horizontal gray line, Horizontal line(light or dark forever)
Bright dot dark dot in panel, Bladder in Polarizer, Polarizer Scratch
Abnormal Display, Bright and dark display alternately
1.Chip lose action
2. IC short or joint iog bad
3. Pannel and vsc connect bad
2. IC short or joint iog bad
3. Pannel and vsc connect bad
White Screen> B/L normal, only white screen display > Maybe caused by surge current and EDS
Black Screen > B/L normal, only Black screen display > Maybe caused by surge current and EDS
FIIcker> Crosstalk > LCD Vcom imbalance
Abnormal Color> Only color abnormal > Capacitance improper bring cross-talk inside LCD panel. 1.Chip lose action. 2.IC short or junction bad. 3. Panel and vsc connect bad
Mechanical Noise> When turn panel,appear cacophony > Caused by Mechanical noise of back-light unit.
Ripple> Concentric circle > Caused by between mechanism and panel
B/L off > B/L lose action > Connect badness between wire and electrode
B/L dark> B/L brightness darker than normal > Connect badness Short between wire and electrode.
B/L wire damaged, B/L wire open, B/L shut down> Operation abnormal or systemic noise Operation, abnormal or systemic noise, Short between lamp housing and wire, Because consume power too much.
F/M > F/M in B/L ,white, black Rotundity or wire like> F/M in B/L unit
Light leakage > Brightness at the bottom of the LCM brighter than normal > B/L unit bad.
Mechanical or B/L
Uniformity> B/L brightness asymmetric > Sheet in B/L unit is uneven
Mount hole > Lack screw or screw damage.
