Hello everyone,
I have this 55" LG 55LF652V-ZA smart TV which suddenly started flashing intermittently every 2 seconds with the backlight.
If I aimed the light bulb of my cell phone I could see the underlying image even in those fractions of time when the LEDs were off and the audio instead came out continuously.
Armed with a lot of space and patience, I decided to open the TV, immediately noticing that a LED had flamed out and also burned a portion of that reflective white panel behind the transparent LED diffusers.

[SOLVED] Corsair vs650 random power off / reboot
after some time I can confirm that by replacing the ic with a WELTREND WT7525Y DIP-14P I solved the random reboot problems on this power supply.
Let's hope this one I bought will last over time.
Thank you all for your invaluable help

Re: Corsair vs650 random power off / reboot
I'm not very expert ... the results of this tester can be useful to the verification you asked me?

Does that 5.1 value that I see on the screen have to be monitored over time or can it be taken for good now?Re: Corsair vs650 random power off /... /> Does that...Leave a comment:

Corsair vs650 random power off / reboot
I have a problem with a power supply vs 650 (of those first version with the orange label) this to be clear:
[url]https://www.corsair.com/it/it/Categorie/Prodotti/Alimentatori/vs-series-config/p/CP-9020098-EU[/url]
the power supply turns on but randomly turns off the pc
immediately after you can turn on the PC and cross your fingers until the next shutdown / reboot.
The 12cm fan runs well
there are no swollen condensers, burns, brown areas
some photos of the components inside:
