Hi it looks like everything works don't know where to test except the 390v in the 2 capacitor in the hot side of the power supply and the weird 180v in the diodes in the cold side that should be discharged it is writin on the circuit no more you can read what is written on the circuit quite srrange color mixiing yellow and white
anyhow i couldn't t read anything else
the backlight is on strong and the screen does not get dark or very dark but no pictures
the mainborad feels a bit hott on the black part i test it to 52 degree's against 34 to 40 on the rest of it

The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
Hey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:
STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.

Hi friends,
I am trying to take good quality pictures of rather large desktop motherboards for a project I'm working on. I had a brilliant idea of scanning them with a flatbed scanner I have but it only focuses on the bits of the board that are flush to the scanning glass. And the through hole components tend to lift the main board from the scanning glass. Everything else just looks out of focus. So it seems that that option wont run.
I have been capturing the images with my iPhone 11 and it's okay but wont capture the whole board. I have to grab it in sections and... -
Hi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...
