Samsung UE55JU6800K with no image on screen.
I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.
Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.

I can't seem to flash a new BIOS normally with the .exe file provided by Lenovo, so I'm looking for help. Every time I try I get an error message that reads "New BIOS region (1000000h) does not match with current (C00000h)"
I've extracted the .bin files from both the UB1/UB2 chip (8MB) and also from the UB3 chip (16MB) using a flash programmer although I am not sure if both need to be flashed or just one. Can I get help getting working .bin files from the latest BIOS version for each chip respectively to see if that works? I've extracted the bios.fd file myself and then...Today, 12:07 PM -

Started with a surface pro 5 repair with battery not fully disconnected and ended with dead touch. Tested with a new touch module and new cable and there still is no touch.
Measured touch power rails 1v8 and 5v, both are present.
From schematics and boardview it seems like everything happens over SPI, the i2c is NC
The MOSI goes directly to the CPU through a 10ohm resistor
MISO also goes to CPU through a 10 ohm resistor but also goes through some buffer/level converter chip (VC125) for SPI sniff im guessing for panel brightness level.
I do not have a scope,...05-01-2024, 12:54 PM -

Dear forum,
I'm stuck with this old TV unit.
PSU: 17PW04-1
MB: 17MB62-1
Symptoms:
- Blue LED constantly blinking when connected to AC.
- Only sigh of life is beeping when touching the capactive buttons on the front.
Diagnostics so far:
Checked the PSU output voltages:
12V present
5V present altought its only around 4.2V
3V is present measured 3.4V.
I check TP 202 which is for the short circuit protection: 0.606V on diode mode
Since I met with some vestel models before with similiar symptoms...Today, 03:18 AM -

Hi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all...04-18-2024, 01:15 PM

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...Today, 03:25 AM -

Hi all,
I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.
After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.
I hope someone can help me out. Attached is my [B]ORIGINAL...Yesterday, 12:18 PM
