#1 Sony KDL48WD650 Identify capacitor and 6-times blinking red LED light

Hello everyone. I received this TV after it had already been tampered with.
When the power button is pressed, the Sony logo appears on the screen, then it restarts, and after three times, the LED flashes red six times.

Based on this symptom, the problem is related to the backlight. Visually inspecting the BD9423EFV area, the capacitor on pin 31 (CP) is damaged, and I need to identify it. Can anyone tell me its value?

I've also ordered replacement LED strips because, according to the tester, they aren't working properly.

Hola a tod@s
Me llego este televisor ya habiendo sido manipulado.
Cuando se pulsa el encendido salen las letras de Sony en pantalla, posteriormente se reinicia, y después de 3 veces, el led se queda parapadeando en rojo durante 6 veces.

Segun este sintoma, el fallo esta relacionado con el backlight. Mirando visualmente la zona del BD9423EFV, el condensador del pin 31 (CP) esta dañado y necesito identificarlo, . ¿Alguien me puede indicar su valor?

Paralelamente, tengo pedidas las tiras leds para sustituirlas porque segun el comprobador, no estan funcionando bien.

Timer latch setting capacitor has to be within the range between 1nF and 2,7µF. Basing on the colour of ceramics it is very likely 1µF/25V.

6 blinks on Sony TV means backlight failure, which corresponds to your test results. Please note that you have to replace all LED strips at once - if you replace just a single faulty strip then one of the others will fail shortly.

After replacing the backlight LED strips, I also recommend increasing the resistance of the backlight current sensing resistor(s) by 10-15% to reduce the current through the LEDs and thus extend their lifespan. This will make the picture slightly darker, but such a small difference is almost not noticeable, and the lifespan of the LEDs will be significantly longer.
