Re: sony bravia lcd klv-37s400a restart
Do you have a camera... can you take pictures of the inside of your TV?
Notice you live in Cote D'iovre, so how easy will it be to get parts? Do you have many electronics shops/distributors?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

"when it starts, it stays on moin one minute and turns off. he does it restart only" look like the digital mainboard is bad (its control on/off and TV function)
open the TV & take picture and pot this threadComment

Re: sony bravia lcd klv-37s400a restart
Hi- Pictures need to be a bit sharper
Examples of what is needed
https://www.badcaps.net/forum/attach...1&d=1290283049
https://www.badcaps.net/forum/attach...7&d=1280167246
It will be useful if you can say a bit about yourself - skills tools etc
Do you have a multimeter and can you use it?.
Can you do a picture of the inverter board - one down left side in pic 1
Do it in 2 halves - overlap
When you switch on does the screen light up then go off.
What do the LEDs do - stay on/ flash/ change colour
"he does it restart only" what do you mean? Does it try to restart after it goes off.

Re: sony bravia lcd klv-37s400a restart
in fact I am a technician and I'm used to depanner.Mais it is now that I work on LCD, PLASMA. Also I have a multimeter that I know and use lots of other equipment. I want to distinguish from other technician here because they do nothing but tinker. Otherwise when you turn on the screen, it stays on for a miniute to moin and he died. and after two minutes, it turns back on then back off. no flashing LED to assert an error code. thank youAttached FilesComment

Re: sony bravia lcd klv-37s400a restart
It might be done with the USB port. Maybe Sony has firmware on their website.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

@milha My post was directed at MADY but if you look at MADY's picture 3 there is a small white fuse just above the connector. It is at F4 which might suggest there are other fuses on that board. Do you have a different board?Please upload pictures using attachment function when ask for help on the repair

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 -

Greetings everyone.
I also have Sony Bravia, model:
Sony Bravia KD43XF7596BAEP - Android.
What happend is that image dissapeared while we were watching tv.
Diagnostics:
1. TV turns on, no errors
2. Backlight turs on, no errors
3. Power indicator turns on, white color, no errors
4. Menu works on android, you can hear sound while switching channels
5. Volume up and down works via TV remote and via buttons
6. Tunner works, HEVC / MPEG-4 decoder works
7. I get audio from channels
8. No picture is present,... -
Before proceeding with a component level repair, the usual troubleshooting process was followed:
1. Disassemble and unplug everything except the power connector.
2. Replace RAM.
3. Replace CPU.
4. Rewrite BIOS.
Unfortunately the board was still stuck with a 0.75A power consumption at 19V.
After reflowing both GPU and north bridge in one shot (it can't hurt) there was an instant improvement with a constant 1.75A power consumption, but I immediately noticed smoke and the typical smell coming from the GPU area.
I thought to myself "Well,...
