    Thunderbolt Monitor problem

    Was thinking I would check this out like it was a TV (what I used to repair) and sure enough used a TV LED tester and several were out. Took screen apart and 2 strips in there and 1 connector had fallen off but tested all and found 6 out also. Thinking I need to get those fixed first as some TVs...

    So even if it charges or runs a macbook with no battery it could still be on the power supply?

    Thunderbolt Monitor problem

    I hope it's ok to ask this here but got in my first thunderbolt monitor A1407 It charges a laptop just fine but nothing comes on the screen. I went to the screen with a high powered light and no picture either. I tried a seperate thunderbolt cable to the port on the back and still nothing. Also...

    Well 2informaticoc I guess you are correct! I got in another A1466 in this week and did a quick swap of the logic boards and screen still did not have an image unless I put on an external monitor. I put the guts in the other one and screen worked as it should. Really weird to me how that works...

    Donor Boards

    I see a lot of people grabbing parts off donor boards, are these something that's just collected over years or where can a person purchase some? Just by old laptops or can one just get boards someplace? I see aliexpress but anyplace else?

    Please be patient with me as I'm a bit new at this stuff and almost all my repairs have been water damage or rework from other shops. I have the wireless card out and the SSD out and the flex cable that goes over the fan off but not sure on what the TP is? With those 3 things off I have...

    Not going to toss a screen when I seen it working just fine. Makes no sense. Is there a chip that controls when to switch between external screen and onboard screen? Also did you see when I said at one time I got zero volts at SMC_LID? Other than the screen what is your best guess?

    Bought through Auction so doing for myself. No other screen to test with. 3/4= 24.5v and 18/19= 3.28v

    OK, 2.45v at DP_INT_HPD but I went and checked SMC_LID right after and 0v now, then suddenly comes back to 3.4v but still nothing on screen. Checked this a few times now and same result. (Head scratcher)

    Yes, used charger and on battery. And yes checked SMC_LID with laptop running with No mage. I will need to check DP_INT_HPD and report back. Thank you for the help.
