    Phillips 47PFL3603D/27 Cold Solder?

    Hi all, just wanted to get your opinion on the photo. Looks like a possible cold solder joint started arcing? If not from cold joint then.... Question is would you take the time to repair the pad, just solder, or look for a new power supply board. Thanks in advance,

      That should be a easy fix, wrap a short chunk of wire around the post and solder it back to the exposed pad

          Caleb's advice is spot on. I have repaired many of these Philips TVs with the same problem. Crappy lead-free solder!
          I just clean up the transformer post and solder in a jumper to the next part on the trace (el65).

              I have repaired many of these Phillips units by just re-flowing all major power passing devices on the smps. I have one running in my outdoor party barn that has been there for a year, in South Texas. They are very good sets..Ahead of their time. Used to see them in all the sports bars..now I know why.

                  Those 2 blue ceramic capacitors fail all the time. You can restore the solder but it will come back , they will either blow up or you will see burn marks as you see it now. I think its the backlight thats failing cause of age , it might ask "to much" power. ( my guess ).

                  IF it happens again then remove those 2 caps , tv will work without them.

                      Acer Helios 500 (PH517-51) - unexpected reboots when laptop is warm (cold solder joint issue?)
                      by Mirenia
                      Hi everyone,

                      got an Acer Helios 500 Laptop (PH517-51) for diagnosing with a strange issue:

                      The laptop runs for a while (1-2 hours, sometimes less) and then suddenly shuts completely off, like someone pulled the power cord and restarts immediately after on its own.
                      If this happened once, then the laptop only runs for a few minutes until restart.
                      This happens regardless while staying in windows or uefi or in a linux environment.

                      At first I thought of a normal overheating issue, but as I monitored temps with HWInfo64, nothing seems very hot.

                      Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
                      by Nagyesz
                      I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

                      All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

                      How can I extend its lifespan? Could reflow help?

                      It has ryzen 5 5500h, rtx 2050, no soldered ram.

                      Example of the artifacts:

                      Best way to solder LVDS connector for beginner (and qfn) ?
                      by corrize
                      Hello, I'm a beginner for micro soldering. Right now I have some difficult to solder a qfn 20, I guess I put too much solder on the thermal-ground pad, the result is a corner of chip wich don't touch the board (last try).

                      I use a wire solder with hot air, I tin the board and chip before with iron and I use good flux.

                      I will have to solder a LVDS connector (40 pins, laptop pc), I saw a solder paste in seringe, good quality (it does not scatter).
                      See the test :

                      Can a microwave oven be used to reflow solder joint?
                      by tmhobadcap
                      I heard somebody suggested a way of repair faulty led light bulb which I have never heard of. The way is to put the led light bulb inside a microwave oven and turn on the microwave oven for a few seconds. He said that faulty led light bulb is usually caused by poor solder joint between the led and the pcb. Putting the bulb inside the microwave oven for a few seconds will heat and reflow the solder joint making it works again.

                      Is that possible? I do not want to try this unless I have a spare microwave oven.

                      (I do not mean to suggest somebody to try this. It may be...

                      UV solder mask - high temp resistent, recomendation?
                      by myth77
                      Can someone recommend any good UV solder mask? But i need a solder mask that will stand high temperetures. The thing is...sometimes i have a bigger cooper ripped from the board, lets say mosfet pad... i reconstract it with cooper sheet, then i "glue it" with solder mask...then i use UV light...and let it cool a bit. After, i try to clean the cooper of extra solder mask..and till that part all is ok. But, when i use a soldering iron to solder that pad/cooper...the solder mask gets weaker or destroyed and finally the pad is ripped again from the board .
                      Is there any solder mask...
