Hi, could you take a look at this dump?
It is from ue50ku6000, chip IC1103_SPI
main bn94-11256D
No standby diode. Is it something you can fix?

What kind of dump is this, where did you think it was from and why, have you even seen this content in a hex editor, it looks like complete garbage.

Hi, I just read it from the chip. Possibly wrong clamp. I've read it again (twice and compared hashes). Also, chip identificaion worked ok - I hope this one is read fine.

This one is completely different, try this one.

[lotas]

Or your corrected one.

No luck, unfortunately. I tried both files, verified with reading and checking sha1 that programming was ok. Possibly something else is a problem (eeprom?). Anyway, thank you for checking.

This suggests that the dump you posted was not original, the dump was not written correctly, or something else was wrong...

Thanks Iotas for the reply. To be safe I made copies of the original dump with other programs. I attach them even if they seem the same to me

These dumps are absolutely all the same.The original dump is considered to be the one that was originally there after the TV broke down, if after that they tried to write other people's dumps there without getting the result, and then read it from the chip, then it will no longer be original.

yes of course, the attached dumps were saved before making changes, immediately after opening the tv

Write in detail how you recorded the dump, what you did, the procedure.

[sirjoe]

Write in detail how you recorded the dump, what you did, the procedure.

I use the ch431 black programmer with clip. After opening the program as administrator, for example NeoProgrammer, I did detect ic and chose w25q40, then read and save.

I ask how you recorded my dump, what you did, describe in detail.

I ask how you recorded my dump, what you did, describe in detail.

I followed the instructions you gave in previous posts, that is:

1. Click "Detect Chip" and select W25Q40CL and "Select IC".
2. Click "Unprotect".
3. Click "Erase IC" and "Yes".
4. Click "Open File" and select your corrected Dump.
5. Press "Program IC" and "Yes".
6. Click "Verify IC".
7. Press the down arrow to the right of "Unprotect" and select "Edition SREG", put a check mark on SRP0+BP1 and CMP+QE and press "Write" and "Yes"

Dear friend, please modify this dumps. Thank You. Martin

Yes, everything here is done correctly.

There are two dumps in the archive, should I fix both?

Yes, in my opinion I can't wait for an answer, I fixed both dumps, try it.

Good solution Yes, I need to repair both of dumps in archive. OP 24082904 - already tested and working, but second dump OP 19020603 still not working. Red LED not lit, TV not turn on..

I corrected both dumps and they are fully working, or I wrote it down incorrectly (didn't install status registers), or there is another problem somewhere..

OK. I used same procedure for programming, verify was OK, so there is possible, that board has a different failure. But voltages are OK and there is no short at board.
Thank You very much for Your time. Martin
