Hello friends,
we recently had a lightning strike near us. Since then, the TV no longer turns on,
The LED flashes 5 times when starting.
I have already opened the TV and made some measurements.
As can be seen in the pictures, the lightning strike has left its mark.
The 13V for the mainboard supply is present.
I can also measure a voltage for the backlight LEDs.
This is about 230V DC. When switching on, this rises by about 10V, and goes back to 230V. This happens about 5 times, after which the TV "gives up". (Measured at the marked points on the board (picture 5)).
The LEDs themselves I tested, they all work.
I think it is because of the current switching to the LED backlight.
However, I don't know which components this could be due to.
Also, the component next to the red capacitor looks a bit "worn". (picture 7)
I would be very happy about your help !
