    LDL-46vl130 problem.

    The symptom: when I first turn on the set, there are two thin (one pixtel wide separated by one pixtel normal) They are clearly visible on light screens, and fade in dark scenes. after about 10 min. they disappear and all is well until the set has been off for an hour so.

    The set has a samsung panel and is a 2007 model.
    Sound like tab bonds?

              did you ever get an answer in this one, truep? I just picked one up for $35 that had what sounds like a similar issue, but I need to figure out what the previous owner did to it first. said he was taking the bezel off, put it back on, and says something shorted out. gotta figure that part out first.

                  That can be tab bond or TFT drive IC (runs hot).

                      tab bonds is what I was hoping. as soon as I get a chance to plug this thing in and get some better info, I'll start a new thread.

                          it was bad tab bonds. T fixed it by adding heat conductive foam above the bond between the bond and frame. It worked fine until I replaced it with a 60" LG and still works in the guest room.

                              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

                              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...

                              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....

                              Dell 15R-5521 keyboard problem (KBC?)
                              by SDNarcia
                              Hello, I have a Dell 15R-5521, with the problem that the Ctrl, Alt, Shitf and Num Lock keys do not work, I tested the keyboard with a keyboard tester and it is functional, I also got another new keyboard and the computer has the same problem with the same keys. Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.

                              As additional information,...
