    hisense 55K321UW help please

    Hi Guys , i am asking for help with my set please , agents say that no parts are available as it has been discontinued now for a while , the set is just over 6 years old
    i will cut to the chase , basically it has RSAG7.820 6135 type main board , 6106 type powersupply and 6137 type t-con board , the standby light is on , psuh the power button and nothing happens , if i disconnect the power supply and hold the power button for 30 seconds etc etc , sometimes it power on right up and will work perfectly again until i switch it off back to standby
    I would really appreciate your help in trying to get it working again and on where to start testing and diagnosing possible failure points
    There is no signs on burning on any of the boards and no signs of bulging caps etc etc , i would like to know what the standby voltage should be as some say it is 3 odd v and others say around 5 v !!
    if anyone has the actual figures and test values and could forward them to me please or post them please i would be most grareful

    Secondly , from sets around 6 years ago to sets around 2 years ago , did the screen types change , for example , mine is supposedly a 4k UHD screen , would a screen from say a 55U6G 55 inch hisense be different to mine ?? , the reason i ask is that if it would or could work , i may be able to get a broken screen hisnese with all the internal bits still functioning 100% , could i transfer the guts of the newer model into the chassis and connect to my screen ??? , could that be a possibility should i not be able to get my set to work again....

    Thanks guys in advance and i hope to hear from someone soon with a starting point

    cheers from rainy south africa

    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...

    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...

    Hisense 55E76GQTUK screen removal?
    by Runlinc
    Hi all, I need to change the backlights in a Hisense 55E76GQTUK. The screen is glued to the chassis, what is the easiest way of delaminating the screen from the chassis please?
    also what double sided tape would you recommend to glue it back in? ….. or is that a question to ask once the screen is out in one piece?
    Many thanks for any ideas you have.

    Samsung UE55JU6800K half screen dark
    by Chrissygizmo
    Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
    I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
