    Samsung 5053X now flashing pixels

    I followed the forums advise on my picture problem. Low and behold it was the video main board. This has resolved 98% of my problems.

    The only thing that remains is that I faintly have multicolored pixels flashing (about 2hz) in the background. I have tried to make voltage adjustments. The pulsing gets better or worse based on the adjustments. Also I can hear a transformer on what I believe the PS board buzz with every pulse. It just seems like I have a voltage out of tolerance that I can't get dialed in "or" yet another problem persists. If Anyone has any advise I would greatly appreciate it. Thank again, Todd.

      Also, the pixel oscillations from the TV seem to be effecting my living room light. Yes the light faintly pulses along with the TV oscillations.

              I guess that is a possibility. I'm going to try plugging into a different circuit as well. I doubt this is the problem being the oscilations on my light fixture only happen when the TV is turned on. I guess its worth a shot. After that I have a feeling I'll be into the power supply board. Thanks! Todd

                  Forget the plug, You have a shield missing or not grounded
                  Open grounded cable etc

                      I have checked for defective shields and could not come up with anything. Any adjustment that I make on either the SMPS, Y-Main or power supply main board changes the intensity of the pulse as well as color. "Playing" with the adjustments can just about get rid of the pulse but will not resolve it totally. The transformer on the Power Supply Main board still buzzes "faintly" with every pulse. If there are any more ideas out there please let me know. Personally I'm leaning toward the PS Main board but any additional help is greatly appreciated!!!!! Thank you, Todd

                          Samsung QE55Q60TAUXXU - flashing backlight and flashing standy light--no image
                          by learnmore
                          Hello Community!

                          CASE DETAILS

                          Promblem Signs: Backlight on 1 sec off 7sec > repeat && Red standby light: 1blink, off 3 sec, 2 blinks, off 5 secs, 2 blinks, off 3 sec, restart cycle

                          13V present on powerboard output. Backlight continues flashing after removing cables to pannel one at a time and even with both disconnected. NOTE: backlight STOPs flashing and remains on when connector between powerboard and mainboard (note Tcon built in) is disconnected.

                          Tried inserting firmware on USB and left it in for a few hours, but no change

                          Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
                          by STKR123
                          As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
                          I wonder if re-flashing the BIOS might be of any use here.

                          As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

                          There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

                          Samsung UE43KU6400U Flashing Red Standby Light
                          by Bloopeta
                          Have a Samsung UE43KU6400U that will not turn on, just continuous flashing red standby light.
                          Power button does nothing

                          Have unplugged the mainboard, and backlights illuminate.
                          Have tried removing panel ribbon cables one at a time, and that makes no change.

                          With mainboard unplugged, all voltages from powerboard seem ok, but with mainboard connected, they never quite reach full voltage, and drop and raise in a constant loop (in time with click noise from mainboard.

                          Using backlight tester, I get 63.6v on both sides, so seems like no bulbs...
