Hello, my UE65MU6102K TV does not start, no red light. When I press the power button I have the action of 1.8V, nothing happens. On the power diodes on the power supply I have 9.4V on the cathodes relative to ground. 3.3 and 1.8v are present on the motherboard. With the remote control nothing happens either

Read the dump with IC1604 (25Q40) programmer and post it here. -
I can't read without desoldering.Comment

HERE IS MY DUMP OF THE 24Q40CLComment

HERE is the dump copied with asprogrammerComment

Why are there two of them, which one is yours? They are different in data.
You read it using a clothespin, but as I understand it, you got two different dumps and they differ greatly from each other (apparently contact was lost)...Last edited by lotas; 03-09-2025, 02:09 PM.Comment

yes my clamp does not hold properly, so I made a second copyComment
-
The second copy is also damaged, try several times, the copies should match each other), if they do not match, then it is better to unsolder this flash and read the data through an adapter, this will be better with 100% quality, and throw the clothespin in the trash, it causes a lot of problems, do not forget that you still need to write a high-quality dump...
And also, with this clothespin you can damage small smd resistors and capacitors that are located around this chip, near its terminals, and then your motherboard will never start.Last edited by lotas; 03-09-2025, 04:41 PM.Comment

If the PSU and Main Bd. can be separated, disconnect the connector from the PSU and plug it into the ac.
If the PSU and Backlights are OK the Backlights should turn ON and remain ON.
If NO then the PSU or Backlights is defective.
If YES then the Main Bd is defective.Comment

You have 100% damaged firmware in 25Q40 (disease in "MU" series!)Comment

the only solution is therefore that I buy a motherboardComment
-
Why buy a new motherboard, I will correct your dump, but I need you to download it correctly, so that there is correct, reliable contact of the chip with the clamp, if you cannot unsolder the chip from the board and read it through the adapter (make 8-10 copies of dumps and I will choose from them, with the best quality).Comment

ok thanks, that's very nice of you. i should maybe solder a soic8 support, in case it happens again i would just have to extract the eprom and reprogram it or make some in advance to be able to replace it quickly in case of recurrence. i bought another clamp of better quality i'm waiting for it. thanks again it's great.Comment

If a new firmware update occurs via the Internet (updates to a new version of the software), then this corrected dump will no longer help, since it is also updated and the old version of the software will not be compatible with the new one.Comment

ok, so the tv has to be disconnected permanently?Comment
-
Why? Why turn it off? I don't get it.Comment
-
So lets clear this up, CAN he update the tv with the dump and will it still work or not.Comment

Hi all I have 2 Samsung LF22T350FHRXEN, working in a dual screen setup. Out of the blue one of them now wont display full resolution trough HDMI port, Either get out of range message or it will be stuck at 1024x768px. Tried reseting the screen, tested different HDMI Cables but with no luck.
Need some advice

Ok.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:

Hello,
i have a bad Samsung SyncMaster 2493hm and i don't know how to fix it. I read many threads on this forum about this monitor but i still didn't got the monitor to work.
When i switch the monitor on with power switch, nothing happens. The blue power LED don't light and pressing buttons on front panel makes nothing.
The monitor has bn44-00195a power board. When i disassemble the monitor and connect the power board with the logic board and switch on the power switch i can measure 5.2V standby signal S_B and 0V PS_ON signal on connector CN851.
On the logic...
