Hello. I was given a bravia kdl-40v2500 that behaves weirdly. I get a picture for 5 minutes, then it turns off, then turns on again, displays picture for 5 minutes, then off again maybe 5 times, then it is permanently off. When it shuts down I get 5 red flashes from the status led in front of the tv. Before I start the process of disassembling the tv I thought I would ask here. Is this typical of faulty caps? Is this a much more serious problem? What is your experience? Thanks for the help.

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).
https://www.badcaps.net/filedata/fetch?id=3591771
https://www.badcaps.net/filedata/fetch?id=3591772
It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times... -
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!...03-06-2024, 12:26 PM -

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
