    T-con 6870C-0267A problem help

    Hi all,
    i have that t-con with a problem.
    IC TPS65162TI is going to be very hot. I have already replaced it without success.
    If i put external 12volt on L1 the absorbment is 450mA and ic go to be hot.
    If i remove L2 ic is not more hot. I checked absorbment on L2 circuit and is just 100mA, also i have replaced L2 without success.

    Checked some short capacitor but nothing. Can someone help me?

    Thank you in advance.

      What is the symptom you are getting that lead you to believe the T-CON is not good?

              Try freezing components around and see if ant others getting hot
              I assume no responsibility for any stupid suggestions I might post.

                  how about checking the load that is connected to the circuit, may be load is drawing too much current.

                      Hi Budm, which load I need to isolate? I have removed L2 coil and seen that without L3 ic is not more hot. But if I put external voltage on output of L2 there is just 100mA absorbent.

                          by THXFX
                          Hi I need help with a Samsung un43nu7100 BN94-13191C/BN41-02635A with boot loop problem even with tcon jumper.
                          I've already try tape method and same happen, if I disconnect both flex from mainboard to panel tv boots normal even I hear Samsung sound.
                          When I solder jumper to make t-con work with or without panel or panel cables connected it still reboot or power cycling.
                          What I noticed is that there's no voltage in VHG, HAVDD, PANEL_3.3V, AVDD_17V or 12v near dc-dc chip.
                          I check capacitors and diodes and didn't find any short IN MAINBOARD.
                          Measured all power supply...

                          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

                          TCL 50S535 bad tcon or panel issue?
                          by x_orange90_x
                          Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                          Driving a Sharp TCON/panel with a universal main board
                          by advant
                          This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                          I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                          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...
