Hello everyone! This is my first thread asking for help and I'm new here so please be nice
I'm trying to repair a Samsung TV but not having much success so I've came across this forum and it seemed kinda nice and friendly. The TV is clicking on/off (relay) and I can't seem to put my finger on the issue. The image looks fine (since I can get a glance at the "Smart TV" logo when it boots). But it's just an endless loop of on/off. If I disconnect the mainboard from the PSU it stops doing the "clicking" sound but that's about it. I've already got a used mainboard... -
Hi all!!
Ok just got a Onkyo SKW-593 sub woofer that has no power person told me that it smoked and that his GF let the volume full when she powered off the amp and when he came to turn it on the sub played but then suddenly smoke was coming out, didn't say from where. So opened it up and saw a resistor made of metal (pic) but can't see any writing on metal par so what ever was written on it was burnt. So I'm kinda stuck here with this. I did ask for a repair or schematics in the other group section and waiting for this but I hope someone here might lend me a hand to try and identify... -
Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).
I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).
Looking on google I found this:... -
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... -
HP 450 g1 keeps turning on even tho I shutdown/sleep . one way to stop the turning on cycle is pressing the power button few seconds thus force powering it off. But then sometimes it does not turn on at all but next day I try again to turn it on and it turns on....
