    Hitachi 32HXC01UB - Intermittent Blank Screen

    I last posted about this box of aggro in 2016 on this forum.
    It's my main set, and yes I know, I could do better..!

    I repaired the LED array in 2016 and again in 2018, it's vital to run the LEDS on LOW setting,which is what I was told to do by you guys.
    Current problem is this,occasionally screen will blank, audio is OK, shining a torch shows LED array is OFF,dim pictures still present,however on powering down by unplugging at mains supply and plugging back in 1 minute later, it sometimes fixes the fault.

    I have the TV on soak at the moment,have accessed the service menu via MENU,4725 and performed a factory reset.I did upgrade the firmware in 2016 to Phoenix V.0.8.4, think I used a USB stick and the service menu to do this.Thanks to Reeceyburger123 for the help at the time.

    Could the fault be corrupted firmware, or as I have yet to check, a fault on the power board 17IPS19-5 or the signals board VO66a 10089336 23175496.This info noted last time the rear cover was removed.
    Your help appreciated.
    Steve..

      One further thought, I did have several power outages a month ago.
      The Reset for the timebeing seems to have done the trick and the TV currently works OK,touch wood!
      However any help/suggestions as to potential faults welcome!
      Cheers

          This Turkish delight had one more surprise in store for me, as an encore it decided to have another backlight failure!
          This will be the third repair since using the set.The backlight array seems to fail every 2 to 3 years even with the backlight set to LOW.
          Just finished fixing it and having a well earned cup of tea.
          This thread is solved for now.
          Cheers

                  I will do that next time it fails, the faulty led was intermittent,I run each strip of 11 leds on a thurlby power supply at 32 volts to test.Have spliced a led in for the time being.

                      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...

                      Hi all, I’ve got a problem I hope someone can help me fixi.
                      I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...

                      Hi guys
                      I'm trying to fix this laptop screen

                      Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

                      OK so I have the original screen which works but has lines across the bottom quarter of the screen

                      I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

                      Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF OLED Blank screen
                      by Kalman27
                      We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.

                      We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.

                      I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.

                      Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller...

                      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...
