    UE37C5100 don't turn on: standby led blink 6 times

    Hello

    I've an Samsung LED UE3c5100

    The TV don't turn on, the standby led blink 6 times .

    I checked the power supply board is OK . All voltage
    I checked all the voltage on the main board ( with service manual) are OK.

    I think it's the EEPROM is corrupt. What is your idea?
    I didn't find the firmware for this TV.
    And with schematics i found there a lot of EEPROM's on this TV. Which the EEPROM for the powering ?

    Thx

    Can we see pictures of the whole back side of the TV showing all the boards?
    How about the control signal Voltages, what do you get?
    Power supply board is BN44-?????

      The power suuply board bn44-00351B
      The power supply is good . All voltage are OK. I made a shunt for the backlight ON/OFF and the backlight is ok.

      I found the all voltage that write in service manual for checking in "no power" section.

        I extracted eeprom files:

        IC501 read at 24C256
        IC502 Read at 24C02
        IC901 - ATMLH038 (i tried to read at 24c01 and 24c02)

        Can you say me if my eeprom dump are ok without faulty.

        I tried to flash with dump from UE32c5100 , without changing only with IC502 with the new dump of ue32c5100 the when i plug the AC cable the standby led don't blink only after press on power button the led blink 6 times and no turning on.

              That's a tough one, you might be on the right track, wonder if it could be a faulty led strip or led short keeping it from coming on.

                  Have to turn on 77” LG C1 multiple times to get to come on

                  Have to turn C1 on and off multiple times for it to fully come on

                  Have to run LG C1 on multiple times for it to fully work

                  If I have it off for a while I have to turn the TV on and off and handful of times for it actually display what it's suppose. The times it doesn't nothing comes up like the input or dobly vision logo. Once it's on I can turn it off and back on fine and the picture looks perfect.

                  Unhooked everything except antenna. Reset tv to factory settings. Let it sit and when I tried 2hrs later turned TV on and sound comes through but no picture....

                  Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

                  Harman Kardon AVR 171S - standby led lights up, does not turn on
                  by madsox
                  Greetings!

                  Thank you in advance for your understanding, I am writing to you through a translator.

                  A Harman Kardon AVR171S amplifier was given.

                  The history of the machine is as follows:
                  It was faulty when I bought it, I want to fix it.
                  I replaced the HDMI switch and one of the DAC ICs in it.
                  After that it worked without a problem.

                  I watched a movie using the amplifier, and at the end the amplifier got really hot.
                  The cooling was faulty, I will fix this later.
                  I switched it to standby mode, waited for...

                  Samsung UE75TU7020k No picture, Standby blinks 2 times
                  by brithepi2k
                  My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board...

                  by matthewmcconaughey
                  Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

                  I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
                  1. It started with a bright and greenish picture upon starting a cold monitor.
                  2. About 2 years ago, only on the cold boot, the screen started to occasionally flash with
