Hi, my tv turned itself off and since than i can't turn it on. I have no standby light.
I tried like i saw on few youtube videos to disconnect the cable that is coming from the main board and than to power on tv, to see if backlight will appear, it did appear but only for a second, and while power cable was attached I noticed small ticking sound from the middle of power board. Than i attached the main board cable again and ticking sound was still present. I guess sound is coming from transformer area, but not sure.
Then i measured stby voltage on the board, and it is below normal value displayed on the board, and it is not stable (4v-5.7v), i got it on the video, when i detach main board cable values are a bit higher (5v-7.5v).
I looked for swollen or leaked caps but didnt found any. What do you think? what should i look for next?
