    Re: Samsung R530 Partial Boot?

    Thanks Steve

    . I'm about to try my 4th bedcap's bios version for the r530. Fingers crossed.
    Unfortunately Samsung's bios download is a windows flash app that i can't run..maybe someone in badcaps knows how?

        Check the LCD cable is connected correctly on the motherboard and scréen

        Cycling colours usually an LCD cable or screen issue

          Cycling colors on screen means lcd is not receiving all input signals.

              heres a video tackling display problem on r530

              https://www.youtube.com/watch?v=pOU3KHlTOSg&t=316s

              Ripping the chipout under the CPU and bridging with capacitors....might work for mine?

                You are not getting display as mb is not posting. You need to measure whether all power rails are generated or not as per schematic. Then need to measure powergood signals of PWM's.

                    The start button is a little hit and miss and won,t always start straight away, usually 5 attempts later, just another symptom that might be relevant?

                        The start button in samsung is always like that. Not an issue here.

                            Samsung 55" TV - Boot loop but sometimes works fine - UE55MU6470U
                            by torchzack
                            Hi Team - just joined to see if anyone can offer some expertise in diagnosing an issue with a TV.

                            I've done a few hours googling and youtubing but just seeing if anyone has any insight here. I got a 55" Samsung UE55MU6470U which seems to boot loop and then after 10 mins will boot, work for a few minutes, then turn off and repeat.

                            Whilst it's on into the normal Samsung menu/boot screen it looks perfect - so I can't see there being any screen issues. I've seen lots of videos with taping across clock lines to diagnose which particular one may be an issue but i don't...

                            Samsung UN40H5003 boot loop every ~8 seconds
                            by eigma
                            Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

                            Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/

                            SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

                            Samsung un82ru88000f - Boot loop sort of but can correct with taping of LVDS ribbon
                            by NolesFan
                            Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...
