    Samsung LE40R87BD

    Hi All
    Could do with some more help with this set ? . The original fault was dead with the led flashing , so I changed caps in p/s set would still not power up so carried out eprom reset shorting pins 5/6 got it to power up and was rewarded with set powered up with back lights on sound but no picture. Then replaced t-con board still no picture , then advised to change ic1830 for a 24c256 so changed this still no picture then I was advised to change main board.
    Now this is where I am having trouble the part number on this board is BN41-00813E-MP1,0 when I search this number it comes up as a Samsung LE32R87BD not LE40R87BD. can any one tell me are these boards the same or does the screen size have any bearing ?
    If any one could help clear this for me and any help where to source a replacement board all sites I have visited say out of stock. Or better still have a working board they can let me have of (course all costs met with in reason)

    Would appreciate any help Regards Ron

      BN41-XXXXXX is the blank board (PCB, board not stuffed with components), you need the PCBA (PCB assembly, board stuffed with parts), that numbers are on the bardcode sticker, in your case, the PCBA is BN94-01472M.

      FYI: Blank board can be stuffed with different components as needed for particular PCBA, so same blank board can be used for so many different PCBA.

        I have used a 32" board in a 40" version of this Tv, did this for price/availability reasons, I only had to enter the service menu and change screen type, version and size.

          Hi budm/Dang
          Thank you for your replies.
          I have been trying to source a board on Google and eBay without success I have seen similar boards with the same parts and connections in the exact same place on the boards but they are for different models or same model number but smaller screen would these work if altered settings in menu ?
          They are practically identical to my board!!
          I think I have seen one board but that was for £70+ far to expensive how do you make a profit when parts are that sort of price just to much to pay to then find out this does not cure the faults.
          Any more help with this set would be much appreciated unfortunately I have not done a lot of work on these flat screens most of my work was carried out on crt's.
          Regards Ron

                Hi All
                Just looking at a picture of a LE37R87BD main board priced at £39.99 +£4.99 pp and it looks identical to my main board. Would this work in my LE40R87BD if I were to change pict size and panel type in the setting ? Any one 100% sure it will.

                Regards Ron

                  Re: Samsung LE40R87BD

                  Quite a common issue--caps in the PSU fail and corrupt the mainboard.

                  Had one today, had to change the M.B. too, grabbed the first one off the pile, bunged it in--it worked, pic size all correct, --I didn't even check the number.....

                  --A working M.B will work--providing the correct Series/Type--even if the number isnt correct generally Good for checking dead sets anyway--
                  --Whether the picture will be completely right and all the options as intended is completely another matter!

                  I suspect it Wasn't from a 40", havent seen many 40's.....

                    Thank you Alastair
                    for your response that makes more sense . Looking at these boards I just can't believe they wouldn't work even on close examination 95% of the components are identical.
                    unfortunately I don't have any M.B to just grab one and test so will have to bite the bullet and send for one and hope I don't loose £45.00 in the process.

                      Guess thats one advantage in working at a Recycling-Centre--Fixing tellys!
                      --Ive got teetering piles of mainboards, PSU's etc all over the place!

                      Never seem to have the part I want though!

                      Tell me all the numbers on your original board, I'll take a look Monday, Maybe Ive got summit, but cannot guarantee functionality, but I'll not charge any more than postage for it.....

                          BN40-00112A is the tuner module P/N. http://sparedparts.com/parts/details...12a_tuner_unit
                          As I indicated, the blank board BN41-00813E can be stuffed to make many different version of the main boardS for many models of the TV.

                              Right, I had three Bordeaux boards.

                              Chance would have it, I had a 37" Sams. with a Bordeaux in too. It had dodgy caps on 24V line, quickly fixed, so I tested the first two I had.

                              One oldish/cruddy/dirty looking one wouldn't boot--so it got booted!

                              The second boots fine, but cannot test for picture, as the LVDS plug is different on the set--Its the full HD 1080p set, (Very unusual, only the second 1080p Ive seen in 6 months, the other was a 37" LG--now in me bedroom!) and has different panel.

                              I note though, this working/booting board has the same socket type as your board. I'll dig it out from car later and give you its numbers, although looking earlier, I couldn't determine the panel size it was intended/set for.

                              The third, I found later in the day and is so far untested, but is marked, 32".

                                Right, Here are some numbers for you--

                                top of board, above that interface-socket, printed in white ident- Bordeaux plus 2007.05.23
                                below that-- BN41-00813E-MP1.0

                                Paper label below interface-socket, --Bordeaux IDTV37, 110619 C818 05

                                Paper label on tuner-- HU 10 BN94-1121S 010026874510 0094

                                Small letters, same label-- Bordeaux IDtv 37" AUO 393A 2007.1/1004/1013 BREDA
                                --There's a metallic plastic label on the tuner, but I believe this relates to the tuner, The DNOS403Mxxx number....

                                So--looks like this board is intended/set for a 37" AUO LCD panel....

                                What make/type panel is your 40"? It'll probably work, but you'll need to set screen-size in the engineer/options menus....

                                  Hi Alastair
                                  Sorry to be so late to answer you but late at work then came home and had to take Grandson to hospital due to a bad cough he also has asthma and he is only five so thought best to take him, But all was ok.
                                  I think you are right with this board a lot of the numbers are very similar and the two numbers printed on the board are identical, As long as all the sockets are in the same place I can't see why it wouldn't work any way I have nothing to lose do I .
                                  If you wouldn't mind sending it to me I would be very grateful.
                                  Do you have a PayPal account Alastair ? if you do I could give you my PayPal email and you could request a payment from me so I can pay for any costs.

                                  Regards Ron

                                          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                          Upon bringing it home and plugging it up, it showed a standby light.

                                          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                          The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                                          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                                          Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                                          by ohren
                                          I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                                          I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                                          The models launched in 2018 and 2019 respectively....
