I have an HP dm4-2165dx. My hdd failed and I replaced it and used the HP factory recovery disks. The video cable had a short in it near the hinge. After I put it back together and turned it on, I heard an electrical "pop" near the top of the keyboard. The display only shows a grey/black screen. It does light up white on the backside. My tv monitor works totally fine.
I already replaced the video cable and tried a new screen. I have done system recovery several times. Memory and hardware diagnostics check out fine. Same problem. I disconnected the lcd inverter and no change on the display. I don't know if the "pop" is related to the problem or not. Could it be the inverter? Is there a replaceable video card? Thanks in advance!!
