    Toshiba C855 (PLF/PLR/CSF/CSR DSC MB)change video from 216-0810028 with 216-0833002

    Hello,

    Unfortunatelly, I have a big problem with a Toshiba Satellite C855, motherboard PLF/PLR/CSF/CSR DSC MB

    First, this laptop have a vertical lines, about 3 cm wide, in with the image was in lines and macroblocks.
    I verified anything, the panel, lvds, ram, etc.
    I presume taht is video chip defect.
    So, I reball the chip, but now I have no video at all.
    I change the chip who was 216-0810028, with another wich code is 216-0833002
    Off course, no video.
    Now I think that is a wrong bios, because is a different chip.

    Is there a way to change the bios for this laptop and exactly for this type of video chip?

    Thank you in advance

    I have the same laptop with the same problem. Original chip 216-0810028 and I put 216-0833000. I read that I can do that change, but black screen. Any help with these Toshiba?

      I had same issue after replacing the chip [I installed the same 216-0810028] and I had black screen until I did a reflow at video RAMS.
      After that it came alive again.
      It is interesting if it can accept other chips also [I guess cheaper ones]

        Thanks for your reply. I gave up on this and I wait to find the right chip.

                If you have tools and skill:
                - Soldering iron or hot air station would be better
                - SPI programmer
                - Skill to solder and desolder a chips
                then consider to fix bios related by ME region issue, upload your bios backup. hope someone can help you
