Does the backlight work if you disconnect the motherboard from the power supply? And what firmware do you need?

Hi Lotas,
I did re-programed the IC successfully, resoldered back onto the board.
No change, no any light on the power switch, nothing happens when power button get pressed. As I mentioned earlier, when main board disconnected from the Power Supply the Screen get lighted in full.
Any suggestion what to do next?

And status register 0x88, 0x42 you set and wrote down after writing my corrected dump, if you didn't set it, then the first time you turn it on, the firmware flies again and it will be the same.

Yes, I did it. Will take the IC back to reading station to confirm the content.

Re: Samsung ue49mu6120

Hi Lotas, my ue49mu6120kxzt doesn't turn on, if I unplug the power supply it turns on the backlight, the first part of the dump has many FFs and from what I've read in this forum I think the SPI is corrupted. The power went out and it happened. I also noticed that from the power supply module the 13v voltage is reduced to about 9v. I'm sending you the dump, can you please fix it? I tried to program the w25q40cl with my modified black CH341A as you recommended inserting the data you sent to iu3ohw (W25Q40CL@SOIC8 _FIX.rar) and I set the status register 0x88 and 0x42 but it didn't work.

Hi Loats,
THX having time for me.

If I look at the dump, there are many YYYYY somewhere after first 1/3 of file? Is this normal?
What else can be a problem?

Do you have some other dump in your database which might work on my TV, I can try?

Re: Samsung ue49mu6120

Hi Lotas, sorry I didn't tell you the result of the flash of the repaired dump right away, it worked and I turned on the tv to see if everything was ok, it worked fine for a couple of hours then the remote stopped working and turned off and turned on by itself then it stopped working, I reprogrammed the flash but it didn't work, I programmed another one removed from a samsung main board but even with that it didn't work, I checked that registers 88 and 42 were OK and that it was write protected, it doesn't work, any advice? Thank you again

Samsung accidentally did not update with new software via an Internet cable or via wi-fi, after it began to work, if it is updated, then the dump that I corrected will no longer fit the new software on your TV.
What is not working now, is the standby LED on?
