    Sony VPC-EB3S1R upgrade video issue

    Hello anyone!
    Sorry for my English.
    I have the notebook VPC-EB3S1R, and have many freetime.
    At first, I resolder video card. 216-0772000 to 216-0772003.
    Can't attach video bios HD5750(1002 68C0). It is not primary problem. I edited video bios HD5650(1002 68C1) and gpu clock and memory clock.
    Now notebook work good. At 650(450 old) MHz GPU and 900(800 old) MHz memory. Cool boost. It is not perfect, but I can't attach other bios.

    At second, I resolder video memory. k4w1g1646e-hc12 to k4w2g1646c-hc11.
    And notebook seen only 1024Mb video memory. I found memory straps on plate, edit it on various combination, but it is no effect. All work but in system see 1024Mb.
    It is primary problem.
    On other notebook Aser Aspire 5820TG after edit straps in system see 2048Mb video memory and use it. And work good.
    May be anyone have a greate idea?
    Thanks in advance.

      Philips 75PFL5704/F7 A Video Issue
      by Nicktronic
      Hey everybody, got a strange one here.

      The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...

      Old Sony VAIO da0hk5mb SVE1512E1E disable Radeon video card
      by bbenalmadena
      I have a Sony VAIO SVE1512E1E (motherboard da0hk5mb) video card is broken, has artifacts, I want to disable it, the processor is an I3-3110M that supposedly has an integrated Intel GPU and I want to disable the onboard Radeon so that can be used.

      I download some schematics, and tried to remove VPL1, but then the laptop starts some leds, and shut off. Should I try to lift VPL1 and VPR47 and pass a cable to one tip of VPR47 and the other back to VPU1 to see if that works or it is pointless?
      That seems to be some feedback to VPU1 and I guess if it does not detect voltage, laptop...

      Sony Bravia KDL-70W850B T-CON board / software update issue
      by eclectric
      Hi, I'm hoping someone can help me with this issue before I give up on this TV.

      In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.

      Here is a rundown of the symptoms and the steps I have taken to troubleshoot:

      I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes...
