    Re: How likely is a cracked panel to short out boards?

    i dont think it is dirt between the glass and those are the best pics i can get.
    there are no other spots on the screen that look like this.
    when i did get screen to light up before there was a fuzzy rainbow effect in that part of screen and the rest lit up white.

      Does the buffer that lines up with it look messed up?

        the buffer that lines up with it fried(ic) when i tried to isolate the bad buffer board.
        before i tried to isolate useing jumper sc50 the screen would not come on.

        im an amateur but to me it seems like a bad screen.
        the pics above have the protective glass filter removed.

          Sorry about your tv. I wasn't aware that a panel could fail that way. I will have to keep a closer eye out when picking them up on Craig's list.

            well im not 100% the panel is bad but it looks like it to me.
            it seems to be between the 2 layers of glass.

            the drawing is aproximatly what it looks like with high magnification.
            each dark line (pic1) is actually 3 lines(pic2) very close together.
            the vertical line(short?) looks to cross several of these wires.

            unless someone can say for sure the panel is good i think im going to junk it

              That's weird. It looks like bad pixels....though very rare on plasmas. If you can confirm that is below the glass which contains the gases for a plasma, then that is not supposed to be there. Doesn't look like what I have seen (mine more like a burnt small smd).

              On a side note: The only reason I found that bad part of the panel was because I was following one of Panasonic's guides and one of their reasoning was a bad panel.

                It is a bad panel.

                  How does the panel go bad on these plasmas? Factory contamination?

                    It is definatly under the glass. It looks like 2 glass sheets glued together with wires between them and seems to be under the first sheet(not the tinted filter).
                    I just got done breaking down the tv for parts today.
                    Thanks for the help.

                      SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
                      by triplefour
                      TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

                      tcon is built into mainboard.
                      Only one cable goes to panel boards.
                      there is a cable from one panel board to the other that links them.
                      cost cutting measure that results in us having harder time to diagnose.
                      removing the link to the second panel board allows TV to stay on with stable backlight but no image.
                      used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

                      Short on PP_VDD_MAIN on iPhone 12, disappears when I split the boards.
                      by SarcasticOP
                      Hello Wise Ones,

                      I am working on an iPhone 12 that fell into a lake and has a short to the main power rail. I do a general look over the board and see no obvious physical issues such as burned-out caps or a split between the boards and the interposer. I separated the top board and the short seemed to disappear. I then checked every test point that I could and they are all not showing a short at all, even the spot where I initially tested. I assumed that something was causing a bridge in the interposer so I removed all the old solder, reapplied some new solder, and sandwiched the boards...

                      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                      by ugamazing
                      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                      Sony KD-65A1 Repair – 4 Red Blinks Error
                      by AK_777
                      Hi everyone!
                      I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

                      Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

                      Extreme High Current & Low Voltage Short Killer ??
                      by DynaxSC
                      Hi Folks

                      I'm looking for a extreme high current short killer solution for a reasonable cost.

                      I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
                      After taking off the socket, the shorts dissappear again.
                      The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...
