KDL-48W605b NO DISPLAY- LED GREEN BACKLIGHT YES

Good morning I have a problem with my tv.

a few weeks ago there was a storm and after a thunderbolt, my TV emitted 3 flashing red LEDs.

power board and motherboard purchased from ebay.

I solved the problem of the red LED but now I do not see any image you hear a rustle for a few seconds and I have the correct backlighting.

can I solve? what can it be? they told me to update the firmware but I can not see the video, so I do not know if it's a good end, I hold down the power button and then plug in the led turns white and blinks for a few seconds then returns green, to sometimes I also have the blue LED.

you can help me?

Buongiorno ho un problema con la mia tv.

qualche settimana fa c'è stato un temporale e dopo un fulmine la mia tv ha emesso 3 led rossi lampeggianti.

scheda di alimentazione e scheda madre acquistate da ebay.

ho risolto il problema del led rosso ma ora non visualizzo nessun imagine si sente un fruscio per pochi secondi e ho retroilluminazione corretta.

vieni posso risolvere? cosa può essere? mi hanno detto di aggiornare il firmware ma non riesco a vedere il video, quindi non so se va un buon fine, tengo premuto il tasto di accensione e poi inserire la presa elettrica il led diventa bianco e lampeggia per qualche secondo poi ritorna verde, a volte ho anche il led blu.

mi potete aiutare?

@giovygap

when you say the “power board and motherboard “ you are talking about the power supply board and the main board, I assume. When you repalced it you made sure that the boards are identical to what you original had in your TV. Since you have backlight but no picture (you did not tell us if you have sound) I am leaning toward a bad main board or a bad tuner board (less likely a bad T-con board)
