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

[zaratustrax]

First at all Thanks for taking the time and check my file.

As you said the problem is some where else. I was looking for and I discovered that the problem is on the panel side.

I made a trick, I dissabled the Tcon protection which detetcs if the panel is connected to the Main board. So I could discovered where the problem was. And it is on the left side.

This tv has two boards in which are Soldered the cofs. So we have a 'board-cof' left and right. And also each one is divided in two board connected through a Coffee color flex.

I cheked this part and I couldnt find any Short or low resistente, I also try to dissabled the board in which the problem is cutting the ckv lines and covering with tape the voltages lines.

At this point I am stuck. I am wondering if the problem are the cofs or this side of the panel is broken or something.

Could you please tell me another way to 'turn off' or dissable this part of the panel in which the problem is?

Again, Thanks a lot for your help

Thanks a lot for your reply.

I made a terrible mistake. You are right, the ic is different. And I could find the correct one.

I attached the file, please clean my bin archive.

Thanks again for your help and guidence

Your dump is fine, working, so the problem is somewhere else, maybe the panel.

Hi everybody.
I have a similar problem with my Samsung Un55mu6300.

When I plug the cable the leds turn on and off. If I disconect the Mainboard the leds keep on.

I was trying to fix and I already programed the bios chip using the programmer tl866ii, but no luck.

Browsing a lot I found this post and I beg you to clear my bin file please.

In addition I want to point that my file is 1024 kbytes Long, but to my surprise the files that the People have uploaded in this topic is half the size. I thought that maybe the chip was touch but ir wasnt. The solder points were old as the other in the board.

If you please clear my file I am going to try the options as describe in post # 4

Thanks in advance for your help

You posted a dump from T-Con, it is responsible for the panel settings - this chip is IC1603 25Q80 (1024k), but you need IC1604 25Q40 (512k) it is responsible for the standby mode, if you saved the dump from 25Q80, put it back and post it from 25Q40!

Right right, I hate regurgitating shit over and over again too, our dear friend Budm would put those things he found he had to keep going over, in his signature, great idea, then he could just say look at #3 below, like pictures, that's going in mine, SOO tired of typing that shit out.

Re: Samsung UN55MU6103F IC1604 dump

hi, I have a tvUE55MU6500U main BN41-02568B BN94-12394N the screen remains black and the TV restarts if I disconnect the panel flats the TV works, with a new main the TV can be seen well so the panel is ok.

I tried to modify the original file with the procedure described with AsProgrammer_2.1.0.13_fix but the TV still doesn't start, maybe I made a mistake?

This dump is working for you, the problem is different.

Yes, it's clear, I know, I'm only uploading it for any member who needs it, it's from a board that's working and that prevented my TV from working

After writing the dump, did you set and write the status register (0x88, 0x42)?
