SAMSUNG UE55MU6405 - no standby

[Jmenuu Zavalichi]

and from the 25q80 is this one

[Jmenuu Zavalichi]

I copy the dump of the original 25Q80 to the new main... but nothing is seen, only the LEDs light up... I put the original dump back to the new main and I see the screen the same as before... I mean the programmer works well for me

[Jmenuu Zavalichi]

Now it seems that copying dump from 25Q80 (original main) to the new main does not work for me, but if I could find the original dump or you could modify the dump from 25q40 (non-standby) of the original board I could possibly recover it

[lotas]

hy there...theat was the dumb i think...from the iriginal main (512kb)...try this....its the same i think

But this dump corresponds to 25Q40, but it is damaged, I restored it, try it, do not forget to install and write status registers (0x88, 0x42) after recording the dump!

[Jmenuu Zavalichi]

Sorry for asking jejje...what y need to do to write status registers after recording the dump

[Jmenuu Zavalichi]

y use this program

In my opinion, this programmer cannot work with status registers, buy a simple CH341A and use the “NeoProgrammer V2.2.0.10” program for it, everything is there.

[lotas]

y use this program

I don’t use such programmers at all, including ch341a...

MAN....YOU ARE THE GOD.....its works perfectly.....the original main tx very much...y will recomend you

[Jmenuu Zavalichi]

I didn't have to enter anything in registration...it was done automatically

[lotas]

MAN....YOU ARE THE GOD.....its works perfectly.....the original main tx very much...y will recomend you

Thank you! Then you're in luck!

Try.

Hello ! I had the same issue that the original totof post with my UE55MU6405, I had written the 25Q40 with the fix given on the 2nd post.
Now my TV power on and all its ok, heuuhh almost ok...

I have a 1cm vertical strong black line at the left ( in front of 2nd cof )
Is a bad version of eeprom dump can cause this problem ??
Do I need to search elsewhere ?

I also checked and cleaned the tow ribbon connectors between Main and panel.

Model on TV : UE55MU6405UXXC
Model on main board : UE55MU6409UXZG
MAIN : BN41-02568B (BN94-12401R P45F)
Panel : CY-KM055HGEV1H
I have a backup dump of my original corrupted 25Q40.

Thanks you everybody !

It's strange that that dump suited you (it has a different software version compared to yours), as for the strip on the panel, this dump has nothing to do with it, it is responsible for the standby mode...
Well, try your own, corrected one.

Ok, thank you a lot, I will try it today !
Could you please explain to me what are in each memory IC1604/25Q40 , IC1603/25Q80 and 24512 Flash ?
Do you know what's going on with the 25Q40 ? Why is it corrupted ?
How do you make this magic ?
Do you have a kind of section memory decoder ? What is this program ? Homemade or Manufacturer tool ?
I keep you informed as soon as possible.

EDIT : I program 25Q40 with the fix. The TV are OK but I already have the vertical strip...
An idea for the strip problem ??

Hello, W25Q40CL dump is bricked I guess. No red light then connected to 220V. All fuses and components seems ok.

Thanks IOTAS , work ok

Hi IOTAS, i have a Samsung HG32EE460SK that doesn't turn on, no backlight, no red standby light. 19v at the power supply output. Heating up the NAND did nothing for me.
Could you look at the dump from the 25Q40 (IC805) and see if you can fix it? It looks like large parts are missing.

Mainboard model is BN41-02468 (BN94-10894P)

Thanks in advance

I also attached dump of the 24C256 incase someone has this model with corrupted IC801.

Unfortunately, I don't have anything for this TV model, I can't check it.
