    polyester film odd problem: mold?

    What would cause caps to grow crystals and the jacket to fall off?
    I never seen this before, has anyone here seen this?

      I have seen this type of corrosion before. High humidity and warm air is usually to blame. Do you live in a coastal area?

          I see that your are from Chilliwack B.C. potential source of salt air moisture. It may be a problem related to a certain manufacturer of the polymer coating epoxy. Not all polyester foil caps have this problem.

            Problem with LG Plasma 60PM6700 - Random power downs
            by theone111
            I have an LG Plasma TV 60PM6700 for the past ~12 years.

            In the last ~3-4 months I have been having some issues.
            1. Problem: It started with random picture disappearing (sound still worked).
              Frequency: Happened about once a week.
              Solution: Had to turn off TV wait a few seconds before turning it on again.
            2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
              Frequency: Happened about once a week.
              Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
            3. Problem: TV shuts down

            Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
            by Zeonalbasta
            i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
            The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

            Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders...

            Lenovo T580 - LCD Panel problem - error 0288
            by perzyk23
            Good morning,
            I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

            Asus Zephyrus M16 / GU603ZW problem
            by lazaro.089
            Full name/ Model: Asus Zephyrus M16 / GU603ZW-M16.I93070T
            CPU: Core i9-12900H
            Onboard 8GB DDR5 4xMT60B1G16HC-48B:A

            Problem: This laptop was brought to the shop with the board already meddled with. Last technician (maybe without the right tools) removed an electrolytic capacitor (PCE9203) sensing resistor (PRS9801) and probably flashed both BIOS (U2802) and VBIOS(U7802).
            The laptop's behavior is: When connected, it tries to power up. CPU powers on, and (allegedly) the power sequence finishes and goes to S0 (PLT_RST = 3.3V). It consumes 600mA, ramps up to 1.100 A and...
