    Here are the results of my testing:
    LDO #1 Pin1 no voltage Pin2 3.30v pin3 5.04v
    LDO #2 Pin1 no voltage Pin2 3.30v pin3 5.04v
    LDO #3 Pin1 no voltage Pin2 3.30v pin3 5.04v

    On the inverter board, all 3 of the fuses read 24.04v on both sides.

    The voltages at the cable plugged into the inverter boardare:
    Pins 1-5 (VDD) 24.04v
    pins 6-10 (GND)
    pin 11 -not used-
    pin 12 (BL ON) 3.27v
    pin 13 (VDIM) 3.27v

    The fuse on the tcon board reads 4.85v on both sides.

    I found specs for the transformer here: http://lcdparts.net/TransformerDetai...ProductID=3502

    The secondary resistance should be about 1.2K between S1 and S2 (or S3 and S4) and the primary resistance should be about 0.5 ohm between P1 and P2.

    I checked all my transformers and found all primary resistances to be .4 ohms.
    I also checked both secondary coils on each of the 6 transformers and all were between 1.19k - 1.20k except one. one of the secondary coils was 1.20k and the other was 2.48k.

    Do you think this is my problem?
    Usually see the secondary windings shorted... but that is definitely faulty

        I just wanted to say thank you to all that helped me with my problem. I installed a replacement inverter board and my tv is up and running again. This thing has Ben sitting around for over a year.

        You guys are awesome! Have a happy holiday!

              problem with replacing lcd screen
              by mmccomputer
              I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
              otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
              If anyone has any information on the subject...

              LCD TV Green/Pink screen problem
              by jimjoe123
              I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

              Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

              Then each time...

              Sony KD-55XG9505 lines on screen problem
              by Chrissygizmo
              Hello again everyone,

              This is my latest mission, to try getting this Sony tv back to normal working order…

              I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

              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...
