As soon as I plug in the TV all I hear is a relay clicking over and over repeatedly.

I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
PSU - BN44-00878A
Symptoms:
The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
A weak clicking sound was coming from the transformer.
Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA
Progress:
After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I... -
Hi everyone,
I require some help with my TV. The TV standby light blicks on and off with a clicking sound (relay?) from the back. After I opened up the TV, I set about troubleshooting by unplugging the boards to try and isolate the problem. My troubleshooting suggests that the logic board is causing the issue, but it could entirely be the YSUS board which is only activated once the logic board is connected.
I have recorded a video which I thought would be an easier way to explain the problem and show the boards at the same time.
I would like to try and identify... -
Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing... -
One of my KP105 smart plugs failed today. It started very rapidly power cycling (you could hear the relay clicking on and off and the LED was going green/orange repeatedly).
I was going to just bin it but I opened it up out of curiosity. Found a swollen cap in the corner (bottom right of image). AiSHi brand, 470uF 10V 105*C. Not sure what purpose it serves exactly so can't comment on whether it is appropriately specced. Other members of this forum have reported similar findings with off-brand smart plugs but this is the first time I have seen evidence of this happening with a brand...
