    Sony Bravia 40cx520 weird issues

    https://youtu.be/jL8y-JpI2rY


    I have a sony bravia 40cx520 tv. thinking i could fix it with a board swap... problem 1. 3 red flashing light code.....

    1a. i get out my multimeter and test standby voltage... 3.3v

    2. i check every connection to the tv, all is good, no dust or corrosion, No damage to any capacitors or resistors or transistors/mosfets that's visiable

    Que> board replacement time, I replace, power board Same 3 red flashing light code... I replace mainboard... that's where things got interesting....

    1. I turn power on..... 0.1second of backlight, just a flash... 2. green and orange light flash at the same time and continue to flash every 0.5 seconds forever, with no breaks or sequence to speak of.... Any ideas ?

    See the video for a bit more info.

    I didn't notice any physical damage to the capacitors

    I have Sony and android logo. but then 4 led red flash lights front of the tv

    I have 3.3v ref. 12v reg then T con 12v when I press the power on button
    but then I get black screen and 4 red flash light at the front LED
    but I get 3 led flash on the LED driver board.

    I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
    so I tried...

    [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
    by ekozeko333
    Hi all,
    I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
    🔥 The Problem Started After Suspected ESD/PD Fault
    I experienced a power issue or ESD event through a USB-C charger
    After that, the NX20P5090 power switch was visibly burned and was replaced
    Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
    🧠 What I’ve Done So Far
    Flashed...

    Sony bravia kdl-43w755c - boot loop
    by justin35
    Hello,
    i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
    from what i read online it looks to be an emmc issue…
    i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
    i took out the board and say an samsung 16gb emmc
    i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
    i could try to put one instead of the 16gb one, but will it work?
    where do i get the software from?
    any help will be much appreciated!...

    Nikon D800 camera - flash don’t work and capacitor don’t charge
    by corrize
    Hello, I'm stuck in troubleshooting…
    The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

    In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
    When I press the flash button, it's detected by the system, flash icon appear on LDC display....

    Sony KLV-37S400A Weird Issues
    by Kyleadonis
    I have a Sony TV that after a few minutes it makes a pop sound through the speakers and then completely switches off and then powers back on by itself, the green LED goes out and then back on again. Since I replaced all the caps on the inverter and power supply its shutdown intervals are longer. I haven't replaced the main filter cap but now I'm just lost on what to do? I've tried resetting but no luck. Anyone know what else to do?...
