    Hello all, my HP laptop display those horizontal lines and sometimes is working fine, I mean after a fresh installation the display recover from that state.
    I have clean the laptop so is not an overheat problem.
    I have check the memory in other laptop and is working fine also I put some new modules in this one and still the issue remains.
    I start the laptop without hdd's but still do not work.
    I disassamble the laptop piece by piece to find something wrong but everything looks fine.
    Please advice!
    Thank you all!

    There's your problem. These chips have a problem with the BGA material (essentially the GPU connection to the motherboard) and over time, the BGA will degrade and eventually the GPU will fail. Reflowing your GPU MIGHT fix the problem temporarily, but it's just a bandaid. You will either need to replace the motherboard or get a new computer.
