    32LX1D dual tuner problem

    Hi, thank you for your help. Your site has been very helpfull for me since now.

    Dual tuner (antenna/cable) When i connect antenna i get a perfect image.
    HDMI input works perfectly too.

    When i connect the cable module to the cable entry i get noise in the image or more vertical line of noise. I get the same problem when using the cable module in the antenna connection.

      Try that cable box on another TV.

          Also, have you tried a different coax cable at the cable entry?

              Disconnected the cable from my TV which was fine and connect direct to this one. Problem is the same at customers house. So not a bad cable or cable box. thanks for the suggestions!

                  You tried a different cable, but did you hook up the cable box to a different TV? Did you verify you don't have any RF leaks up the pole on the splitter? Pretty easy to find with a TDA and spectrum analyzer.

                      I've had the same issue on several on these and the 26" versions. The fault was evident also on composite input and the VGA input. I suggest trying those inputs as well. I never did resolve the issue as the customer never wanted to spend any money on replacement board. I have a suspicion it is related to the analog section of the main boards

                          Thank you guys, yes the cable box was hooked up on my personal TV and working great before doing the test on the defective tv.
                          I appreciate your input Nicholas1110, i will try other inputs as mentionned. i'll let you know...

                                  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

                                  Problem

                                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                  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...

                                  Good evening, gentlemen.

                                  I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

                                  To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.
