    I have a PB15, 1.5ghz, which has screen problems. Can I fix them myself, or should I take it to be repaired?

    Problem 1: Bottom inch of screen sometimes goes black or freezes. Often happens when opening LCD. Moving the LCD a bit more and wiggling it a bit will fix the problem for a few hours.

    Noob diagnosis - loose LCD ribbon cable - fix by opening PB and reseating cable. No idea if this is actually the right solution.

    Problem 2. Roof of my house developed a leak, water dripped on my sleeping PB15 overnight. After drying out, PB internals were fine, but screen backlight was gone. Can still read the screen very dimly, and am posting this with a CRT monitor hooked to the PB.

    Noob diagnosis - Open LCD and replace something. But what? the LCD bulb or the inverter board or both and/or something else?

    Can I do this myself? No idea how to check what's actually broken :(

    My background is I'm comfortable opening up and building my own computers - I built my own G3 powermac RAID5 array. I've also dismantled various household applicances to see how they worked - VCRs, TVs, washing machines, microwaves etc.

    I have very little experience with multimeters and soldering irons though I do possess both of them.

    What do you think?

    I think tightening the GPU cable is manageable for you. Check out the iFixit guides to see whether you agree. I think replacing the LCD bulb and/or inverter would be a bit tricky though, personally. :eek:

    Good luck with whatever you try. :)

    Could you not claim on the household insurance?

    No household insurance. Decided we were paying more in premiums than the benefit we were getting (we don't have much expensive stuff, apart from our laptops, which were likely to not be covered anyway)

    Some work came in, and I need my PB, so took it to MicroMend in Tottenham Road yesterday, see
