Member: 9700 Status: Offline Thanks Meter: 62 | 9210 LCD dirty problem when I press strongly on keyboard (near w,e,r keys)... image goes on and off partially (with a lot of small horizontal lines). By watching this I have conclused it's flex connector or flex cable problem, changed flex cable but still same, changed LCD but persists. the only way to solve this is changing main PCB! (tested) but I don't know why... pcb connector to flex is ok, I have resoldered it, reflowed philips ic's (lcd drivers) but allwais defective image sorry for my large message, I'm waiting for expert advices. I'm going crazy with 9210s pcs  thanks in advance b.r. |
