    first.. before you had damaged ribbon cable they where lost of silver pins contact.. did you clean the sockets of the panel and t- con with brust before you install the replacment one.. to me this what happened. if you take one by one and clean the sockets to be sure they are clean.

    second. this effect are much caused by yours t-con.. you are hurry man. to remove the cable of the test ... you should try the other t-con at same test. up to you.

      Will clean connectors and cables. I haven't done this before.
      Could try the another T-con too.

        Project is over.
        i did test with my T-con again and the replacement T-con. this t-con had issue if you remember that there was a white line on left side going down with the replacement t-con. if it reached the end of the screen, right side went bit brighter with freezed horizontal lines.
        left side was bright.
        i was 40 cm away from left side and i feeled the air gets hotter. i touched it and HOLY SHIT was this hot!!!
        measured 86°c!! after one minute.

        Want to thank all here for helping... it was interesting and fun.

          A1466 Dead and Not turning on. Had repaired it before
          by MyronViegas
          Hi guys, I have an A1466 (820-00165-A) board which came in dead, had corrosion on R7181 near ISL6259 chip. I removed corrosion and replace R7181 and the macbook powered on.

          After sometime I didn't get any light on the charger but fan was spinning and I was getting battery charge logo on the screen, so I replaced the ISL6259 chip and it came on! everything was working fine.

          (NOTE: Customer had previously got the battery replaced from another shop and it was third party bad quality)

          I had used my test SSD and my known good original battery.

          How can I be sure that my EC chip is dead?
          by double_DD
          Hi all,

          As the title suggests, how can I be sure that my EC chip is really dead?

          I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

          Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

          Haier TV Not Turning On--Completely Dead with No standby light
          by djaywilly
          I have a Haier 50" LE50d3505b television that is "dead." No image, no standby lights, no sound, no nothing. The power supply board is HKL-500201A, and physical inspection looks good. I have tested the fuse (works) and the bridge rectifier (works). Also, the capacitors are not "puffy." However, a couple diodes seem to have faulty test results. I have tested diodes 10/11 using the "diode setting" on my multi-meter. I got .000 readings for both. For diodes 13/14, I got .177 for both readings. Do you think just these diodes are the issue? If so....would these be...

          Chieftec GPS-450-AA with dead 20N60C3
          by zunasthegreat
          Hello everyone hope all doing well!
          I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...
