back to work. I photographed both boards and only modified the resistors on board A (ebay), the areas where I intervened are marked with a circle. No legible image has yet appeared, just vertical scratches... unfortunately I don't have a manual and I'm not sure which resistors to modify, if it's possible to have access to this information or the board's manual that would be great... thank you....

good morning.
back to work. I photographed both boards and only modified the resistors on board A (ebay), the areas where I intervened are marked with a circle. No legible image has yet appeared, just vertical scratches... unfortunately I don't have a manual and I'm not sure which resistors to modify, if it's possible to have access to this information or the board's manual that would be great... thank you.... -
hello again... Next Monday, when I return to work I will compare the two boards next to the TCON area, the panel in question is BN95-05417A 55S1AU0SN, the board I bought from ebay was, according to the seller, a broken TV. Have a nice weekend and thank you very much for your support.

I'm sorry, I don't know what happened, I didn't edit the topic but in fact the dumps disappeared from the initial post, I don't think I broke any rules, until the user "Diah" saw them... I'll post here again. thanks...Leave a comment:

Sorry my friend... I didn't read your answer carefully, so I definitely have 2 boards with problems other than the eeprom... thanks anyway....Leave a comment:

My programmer for read/write that devices is the XGecu Pro TL866II-Plus, it automatically detects the flash parameters, such as manufacturer, capacity, ID, etc... I've been using it for a few years and without any problems so far, I don't think the problem should come from there.
thank you....Leave a comment:

Samsung UE55NU8005T , rebooting , no picture , no backlight
Good morning.
the original board of this equipment is in reboots without giving an image or turning on the backlight, the board code is BN94-12926P (BN41-02636), I made a copy of the flash ic1603 and ic1604, dumps attached. I tried to put other dumps (from other popis models I didn't find this board) but without success. That said, I bought a board on ebay BN94-12926A, which in principle should at least give image, even if with defects, this board turns on and responds to the command but does not give any indication of image despite the availability of VHG and VGL voltages as well... -
however, with the help of boardview I verify that the P_1VS8_PWRGD and 1.35V_PWRGD have a very low resistance (around 10 ohm) after turning off the machine. With the removal of the PU8300 the symptom of not turning it back on remains but with the removal of the PU8600 the machine stopped turning off or rather it turns off and then turns back on again, I have already ordered these components to be replaced, I hope for news soon.Leave a comment:

Asus N550JV rev 2.1 motherboard ... no more power after shutdown...
hello forum
I have this board on the bench... it works fine and ok when it is started for the first time and without RTC battery... then Windows works fine with all peripherals connected without any apparent problem... but when I give the order to turn it off it never turns on again... the voltage on the power key is stable at 3.3v and goes to 0 when pressed, this information reaches the IO on pin 110 correctly... the only way to turn the machine back on is to remove the battery and disconnect the charger.
Thanks... Rui.
