    Ve910b - on/off

    Hi everyone,
    I have three Ve910b monitors that flicker 'on' and 'off'. I took a risk today, and opened them up I was hoping to see many bad caps that I could easily replace Out of all three boards I only found 1 bad cap (at least what I think is a bad cap). Does anyone have any experience with the Ve910b or can help me figure out what is wrong with the boards? Thanks!

    Please start with posting clear focused pictures of your boards using the manage attachments function. Please do not post inline.

    After seeing the pictures, we can make suggestions.

    If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

    We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

      Thanks for the reply! Attached are pictures of the boards.

      There are three boards from the three monitors, all were bought around the same time, same models, and all have the same problem. I have named the images with suffix bX where X is the board number (1 to 3).

      On board 1 I noticed a budge in a capacitor, I am thinking this might be causing the problem? But I don't know what it could be on the other boards thanks for helping me out!

        I attached four more pictures. I am not sure what angles are the most informative.

        Thanks again!

          All I can say is WOW! All three monitors failing at the same time with the same problem. And an unusual board design to boot. The flickering problem is likely caused by bad caps. Yes, that photo of the suspect cap indicates it is definitely bad. The caps that are branded "Elite" are pure junk and should be replaced on sight. Replace them ALL except for the large 450V cap (unless it's bulged or leaking).

              I forgot to mention that the replacement caps should be low-esr like the Panasonic FM or FC series that are readily available from digikey.com.

                  Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                  by ugamazing
                  I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                  We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                  Samsung flicker - BN44-00932T board or else?
                  by fixit007
                  I picked up this TV that the prior owner said - just died.

                  Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!

                  Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.

                  Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick...

                  Apple M1 Boards & Exclamatory Error?
                  by ugamazing
                  We've now created a stack of 10 boards that have the same issue, which we suspect to be CPU-related. The issue is very simple--the board will not boot to anything, only showing the exclamatory sign inside a circle. No amount of DFU/restore, wipe/erase, etc, will resolve the issue. No boards have physical damage. We went ahead and replaced the SSD nands on two boards (one 02020, one 02016) and the issue remained exactly the same. We are considering replacing the CPU on one of the boards using a locked CPU, just so we can see if it resolves the issue.

                  Has anyone else run into this...

                  Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
                  by ugamazing
                  I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

                  Legion 5 PRO, 3 boards, same problem, NM-D562 Rev. 3.0 motherboard
                  by hopkok
                  Hi friends, last week I got 3 same boards for repair (NM-D562 Rev. 3.0), same problem, power button light up, but motherboard wont start.

                  3,3V_alw and 5V_alw, 1,8V_alw and 0,75V_alw presented on all 3 boards, no other voltages. 1,2V missing and if I checked schematic right, I need 1,2V and than can be +3VS and +5VS generated after getting SUSP_N signal from KBC? or vise versa?

                  I checked for low resistance on coils, no low resistance.

                  Anyone with same issue like me?

                  Thanks for any help.
