Panasonic TV TX -42AS500B backlit flashes 3times n red Led blinks

Hi
I have a problem with the Panasonic TV, as in the subject, after turning on the backlight blinks three times and the red power led begins to blink.
I have replaced the power board TNPA5916 1 P TXN/P1JAVEZ as I noticed PCB colour changed due to overheat. But this problem still persists. I read a similar post earlier where the backlight strip a diode was damaged it was changed and got fixed. https://www.elektroda.com/rtvforum/topic3422944.html
Can anyone let me know if possible with pictures which diode it could be? Many Thanks.

I don't quite understand you want a photo of an example matrix?
