TV backlight issue with Vestel power supply board

Hello, could you help me?
I have a problem with my TV.
When I turn it on, the backlight flashes and then nothing.
I have sound and when I use my phone's flash, I can see an image.
I tested the output to the backlight (on the power board) at startup and I have 25 volts, then a decrease until it reaches 0.
Have you ever encountered this problem with a Vestel 17IPS62 board for a HighOne TV?
Thank you in advance.

Hello ph.bgn,
Aside from replacing the power board, I don't see any other solutions (I don't think you can repair it at home).
It can be found as a spare part, and your ability to do so.
Best regards!

but I have voltage and I have an image, sound, and indicators so I have electricity
on the board I tested the capacitors and they are fine
I have a doubt about the LEDs but they flash on startup

Very well! And which component on the board do you have in mind?
It's a Vestel 17IPS62

I prefer to change a capacitor, a resistor at 30 cents rather than the whole board for 30€.
But since I'm stuck on the diagnosis of the board because everything seems fine, I thought that someone might know the exact fault (which is apparently common).
