I have a HP Pavilion dv2000 laptop with a dim display. Normally this problem is cause by bad back light or lcd inverter. I have replace both the whole lcd panel & inverter and still have the same dim display. I also went ahead and replace the video ribbon cable also but still have the same problem. Any suggestion on what else i can try? Thanks. 作者: 会走的鱼 时间: 2011-4-16 23:04

应该是高压条没正常工作吧,既然你换过屏线跟高压条,那应该是3.3V的开启信号没发送过来,直接从屏接口附近飞个3.3V到开启信号脚试下··作者: 维修公司 时间: 2011-4-16 23:17
能确定是暗屏吗,如果是黑屏,那应当是显卡,,作者: 默默修板人 时间: 2011-4-16 23:20
楼主是外国朋友不成,你说的是暗屏吧,高压条的开启信号查过没有,这机子显卡通病,修到过显卡造成暗屏的。。。作者: 若风 时间: 2011-4-16 23:40 本帖最后由 若风 于 2011-4-16 23:41 编辑

Dark screen still another possibility is that the motherboard to control the dimming filter capacitor voltage is pulled down. Look again at the control circuit.作者: 武林大侠 时间: 2011-4-19 17:15
