Samsung UE49MU6450 No turn on no led st.by . Hi everyone i think it's the problem with IC1604 mainboard BN94-12399N - BN41-02568B . Attach the original dump . For TL866 II Plus program Xgpro software , maybe perhaps requires special procedures for to program ? Thanks in advance .

Try.

Didn't find any other programmable IC, must be the nand W29N01HVSINF. thank you so much for your help

Well, I don’t know what kind of motherboard you have, but the NAND is F59L1G81MA-25TI.

It's hard to tell from this photo, but the eeprom should be 24c256.

yes, the samsung logo shows off for several seconds with backlight on then the logo goes off and backlight stays on for some seconds then the tv reboots. i cant find the eeprom ic. photo of the board attached.
thanks for your help.

Anything could be wrong, for example, the firmware in the NAND or in the eeprom, is your backlight OK?

Hello, here is a UE50MU7000 with BN41-02568B (after an electricity jump):
- no stand by led light
- power supply has 9v outputs which go to mainboard
- without mainboard connected backlight works fine
- without backlight connected still no stand by led light
- dumped 24C512, 25Q40, 25Q80 (through CH341A programmer before finding this site), and flashed backup data from a UE40MU6102KXXH (which has same main board), this did not fix anything

After reading this thread, found out there is a specific way of flashing 25Q40, so I've placed all original backups back to their chips (also tried to restore header data in 25Q40, but it did not work)
and while doing what is in guide in 4th post, found out that QE is impossible to check. (edit: in NeoProgrammer V2.2.0.10 it's possible)

Is there also a special way of flashing 24C512 and 25Q80 like 25Q40 requires?
Can you please take a look at these files and see if there is anything wrong?
Can send a thanks thru PayPal if it will fix this issue.

Try it, don't forget about the register status (0x88, 0x42) after writing my dump.

What's better? Open your photos yourself and see how visible the markings are on the chips, replace the camera and take a photo with good focus!
