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

ASprogrammer software only works with the CH341A ,it is not meant to work with the RT809F. The RT809F is a good programmer, chip support can be added manually if the chip is not in the latest support list.Comment

by YanlebHi all,
My UN65MU6300FXZC is dead and the standby LED stays off. The power supply is good. The main board is BN94-12434A.
Disconnecting the main board from the power supply makes the backlight come ON.
I did disconnect the panel cables and the WIFI modules, the board is still dead.
I did read in many posts that IC1604 25Q40 becomes corrupted. It has proper 3.3 volt on VCC pin 8. I did read that if I post its dump here someone can fix it. Is that right?
Thanks. -
by ogabugaHello, I need a dump of the BIOS_WHP1 /25Q40/, EC controller chip /NTC6686D/. The motherboard is coming for repair after a another service, what is in the dump that I downloaded is the beginning of the MAIN BIOS, according to the analysis that I did based on the documentation of the EC controller NTC6686D, the content should be different. BIOS_WHP1 /25Q40/ is connected directly to SCE1#, SO1, SI1, SCK1 pins 66, 68, 67, 69 of the NTC6686Dā

by alro7779Hello, everyone!
A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,... -
by totofCould you help me...
I have a Samsung UE55MU6102K with the following problem : I disconnect the motherboard from main power supply from and the backlight leds light up.
Then motherboard connected, standby led is on and current consuption is 18W.
Then trying to start the TV, the standby led is blinking once but TV don't start and standby led stay red.
Maybe the firmware in the IC SPI Flash W25Q40CL (IC1604) is corrupted.
The model of my TV is :
Power supply BN44-00807A
Main Board BN41-02568B / BN94-12765W
Panel CY-GM055HGLV3H... -
by MireniaHi everyone,
I've got a Samsung UEMU6199U which has no Standby LED and no reaction if try turning it on.
Voltages on the power supply board is okay. Backlight test is also okay.
I read about a corrupt firmware on IC1604 on some models, did a dump of this IC and turns out: First sectors are empty.
So I think my TV has exactly this issue.
Can someone please fix the dump?
And how do you do that?
As I understand you fill in the empty sectors and leave the rest as it is. But where do you get the "information" of what you... - Loading...
