Samsung "MU" series (UN, UA, UExxMUxxxx) fault dump IC1604 25Q40...

[lotas]

What program did you use?
NeoProgrammer V2.2.0.10 ?
Did you program the chip through a clothespin or solder the chip through an adapter?

Was this dump native, original, status register (0x88, 0x42) written after recording the dump?

Yes the dump was the original native one, status register done, i followed the instruction on the post #4

What initially happened to the TV? In service mode, at the point you clicked on “Micom Update” and after that the TV stopped turning on?
If yes, then the firmware has been erased in micom, you need to program it.
And also, you have some strange dump 24C512, or it is so badly damaged or poorly read, try this one.

Where did you get the idea that the problem is in these firmwares, if there is no standby mode and the LED is not on, then a common problem in this chassis is IC204 (stabilizer from 5v to 3.3v) and micom Weltrend, check the resistance at 1.2 pin IC203 relative ground and is there 3.3v power on these pins

Thanks for your your support. i found that sub eeprom (24c02) is connected to this ic1203 so i thought this may be the problem.
I measured the regulator and i/p 5.3 v & o/p 3.3 v so it is good, also the voltage at pin 1&2 3.3v and no short with ground. i tried to press the reset button but nothing happened

how can i check ic1203 (61P805) is healthy ??
does it need programing? if yes can it be done by CH341?

Hi Lotas, my TV model is UN50MU6100GCZB, Board Code: BN41-02568B from Argentina. I'm having the same issue as another user before. The standby LED turns on for 1 sec every 15 sec. When Flashing an incorrect bin, the board stays completely dead. So I guess it could be bios related. could you help me? Thanks in advance

Strange damage to the dump, usually if in this series the MU dump is damaged at the beginning of the dump, then the TV's standby LED does not light up at all. Try this one, I adjusted it a little, and don’t forget about the status register after recording the dump.

Hi Lotas,

I tried with the fix file but the TV set is dead. The standby LED turns on for 1 sec every 15 sec. The standby voltage from 8v goes to 13v. At first, the TV was totally dead. Now it looks like there is some life in it but there must be a hardware problem in the mainboard.
Anyway, I want to thank you for your effort and time. I wish you the best. Thank you.
