Hi Guys,
Trying to fix another TV (now have a small pile of them that I'm struggling with).
The unit was turning on, and after a short amount of time, the backlights would stay on but the signal to the unit would just stop and then slowly fade away off screen (logic board issue?).
I found a swollen cap in the PSU which I replaced - on the 24V side of things. Made no difference.
The PSU was making a bit of noise in the top right, which using a straw I found to be one of the large red ceramic capacitors. I decided that perhaps the power was failing to the logic board, so thought I'd investigate further.
I decided to resolder the joints for the two transformers and the toroid coils on that side of the PCB.
After that, the unit no longer turns on and instead I'm getting a fast clicking. I can't work out what I could have done wrong! I've checked everything I've soldered and all appears to be in order
What does the sound in the MP3 file I've attached indicate? Is it arcing, or the safety mechanism of it trying to turn on/off?
