Graphics chip corrupted
Is there any simple way to fix a corrupted graphics chip on an IBM T41
Thinkpad? The only thing I can think of is to solder a new one on, which sounds like a really bad idea. Is there some troubleshooting steps? Like, can you flash the chip? Or reload the firmware or something? Anything? My symptoms are lots of vertical coloured lines at startup and in Windows. The LCD is unviewable and the same image appears when connecting a monitor. Any advice welcome. Thanks. |

Hi!
Before suspecting the video chip, check the VRAMs that go with it. Colored lines (or lines of any sort) are usually what you see when the video RAM goes bad. Video chips themselves usually fail in more interesting ways. While I doubt you can solder a new video chip in place, you can certainly try replacing the VRAMs if you have enough soldering skill (or you get lucky and they're soldered!). William |

writes Just a cheaper-easier thought: the ribbon cable from computer half to LCD half's a consistent weak link across laptops. Check it. Is it frayed or loose or inconsistent? Maybe you can replace it. It's unlikely to be the graphics chip itself The OP said that the fault was present with an external monitor as well. -- Clint Sharp |
