    Mitsubishi DLP WD-82737 stuck on Welcome Screen Repair Advice

    My WD-82737 is hanging on the blue welcome screen. I did the firmware update and it worked for 2 weeks. I did firmware update a couple more times and got it to boot but the color was blotchy then it went back to hanging on startup screen. I have heard this indicates a bad power board and or main board. I found this chassis kit on shop jimmy (Out of Stock) https://www.shopjimmy.com/mitsubishi...is.htm?alert=1

    I could probably install it myself. If I can get the part.

    Is there a way to diagnose this better? What would a tech charge for that repair approximately?

    Any advice is greatly appreciated.

      I found a power board on ebay and installed it................ still stuck on welcome screen. So I guess it is the main board. Is there another component which could be the culprit?

          Can you make some straight shot, high resolution pictures of your main board?

              Looking at the service manual and seeing the large bga chip IC5A01, That would be one of my suspects, bad bga connections. I guess there could also be a fault on the dmd board?
              Try a system reset " press and hold the POWER button for 8 seconds"

                  Thanks to all who responded. I installed a used mainboard for less than a C-note and the TV is fixed

                      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                      by Ryan.man
                      Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                      My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                      This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                      Lenovo Thinkpad E14 Gen3 stuck on "To interrupt normal startup, press Enter" screen
                      by BMCappelletti
                      Hi everyone.
                      Lenovo Thinkpad E14 Gen 3, stuck on the "To interrupt normal startup, press Enter" screen.
                      Found a lot of people with this issue, but with no definitive answer. Some people managed to get away accessing BIOS, going to Startup and turning off "Option Key Display". For me that only removed the interrupt normal start up message, leaving only the Lenovo logo.
                      Most people say hitting Enter does not work. It's true, if you wait a few seconds. But if you hit Enter right away you get the options to enter BIOS (which works), run diagnostics (goes to a...

                      Macbook Air M2 A2681 Kernel panics after screen replacement
                      by reformatt
                      Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                      It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

                      iphone XS turns off when press on screen.
                      by smic717394
                      Hi,

                      I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
