    Samsung LN46A530 image issue when power on

    Hi,

    I have a Samsung LN46A530 TV with an issue at power on. At first, the TV was powering on/off and clicking. I change 3 bad caps on the PSU and the issue was fix.

    But, at power on a part of the screen is very dark and change progressively to be OK after 3 to 10 sec. I checked the connection at the t-con board and all seem to be ok.

    Is someone have any idea of the source of the problem?

          I don't think the problem come from the backlight.

          With a video it will be easier

              Panel is bad on that side, the side tabs voltage need to be isolated with tape cut-off method or they need to be removed if possible.
              https://www.badcaps.net/forum/showthread.php?t=87395 This is a TV I had and the symptom is very similar.

                  Samsung UN60ES6500FXZA Power Supply Issue
                  by Cookybaby
                  Hello Everyone, this is my first post and I am excited to be a part of such a great community. I've been reading these forums for awhile and there really is some good friendly people here. No bashing and being rude like 90% of other forums Ive been to. Lets get to the good stuff.

                  I have two years of college in Electronics Engineering Technology. Ive been tinkering with electronics sine about 1990. I know enough just to be dangerous, so be gentle.

                  Make: Samsung
                  Model: UN60ES6500FXZA
                  Power Supply P/N: BN44-00525A

                  Samsung QN49Q70RAFXZA Power Cycling Issue
                  by Drewwol11
                  Hi all,

                  My Samsung TV display recently stopped working while I was playing PS4 (no storm or anything to indicate a power surge). I could still hear audio through the PS4 but no display. The TV kept trying to turn on but would turn off after a second or two.

                  I tried the obvious troubleshooting steps like unplugging, replugging, trying different outlets and power cords with no luck. Someone on another forum suggested that it may be a power supply issue so I purchased a replacement power supply board but that did not help. I then disconnected the main board from the...

                  Samsung Plasma TV Power Supply Issue
                  by lp20th
                  I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the...

                  Samsung UN43NU6950FXZA No power
                  by mrtek
                  Hi

                  Picked up another TV. Samsung UN43NU6950FXZA. No power and no standBy led on. Removed back cover and:
                  Main fuse = OK
                  Back light LED = OK. Power them with aux power source
                  LED output = OK 156V
                  I do get 12 V DC out of the power supply going to the digital section but no 5V or 3.3V. PS_on voltage is only 1.8V. I have looked everywhere on the PCB , I could not find i reference for 5V output.
                  Also removed connections to panel, speakers and remote but no luck. One strange thing is that even with the LED power supply working, backlight LED do not turn on...

                  Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
                  by justice171
                  I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.

                  Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:
                  1. Verified that all critical voltages are present:
                    • 3.3V and 5V are always present if DC is plugged.
                    • 1.8V on the BIOS chip is present.
                  2. Checked the power button functionality:
                    • When pressed, the voltage drops to 0V, indicating the button is functional.
                  3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
                    • Confirmed connectivity is intact, ruling out issues
                  ...
