Huge thank you to our veteran members
I am a novice when it comes to repairing TV's. To date I have repaired a Sanyo 46 inch LCD, a Phillips 37 inch LCD, and a Vizio 42 inch LCD. I have done this only because of the help of this site. I am a little proud when it comes to asking for help and with extensive reading, I have a better understanding of TV's. When I started, I didn't even know what parts were involved with a tv. I chuckle when I see people ask for help and they do not even know how to use a meter. You veterans have a lot of patience. thank you, thank you for your dedicated support.

Tore apart a dc power supply/rectifier at work, and there were 3- 32000μF 40VDC caps in it. Any use for them before I get rid of them? -
How to deal with huge LCD screen when we are replacing the TV LED backlight?
Does anyone have a better way to deal with 70-inch TV or above LCD screens which are very easy to break when we change the LED backlight?
I'd broken 10 TV screens already.
One of my friend has 75 inch edge TV with one LED not working. I said : just leave it alone.
Is there a better way to ensure that the LED TV screen will not break? I need 100%. I can't afford the Robot either. -
Hello
Sadly, I accidentally shorted the 5V power pin of the USB port to around 20V power, and the laptop turned off and will not turn on anymore. I hear hissing sound in the motherboard like there's a short circuit somewhere. I tried disconnecting and reconnecting the battery but with not luck, also on the USB-C power it is the same.
I did try and traced the 5V rail and I found this IC overheating. I did remove it after a huge struggle for long but the short is still there. Also the laptop still doesn't turn on and the charger light doesn't light when plugged..

I am working on automated fan speed for lab psu... the fan is 24v 0.15A, and I am connected it to 820 ohm to ground, that provide minimum silent air flow on startup. It is powered around 4v at minimum point. Parallel to resistor I connected BD139, that drive a 10k NTC. Everything work like expected, but in extended test, where I isolate NTC, I have few issues, and like to ask here for help. 1. If ntc is not connected to heatsink, it go slowly to heat up and up and fan make noise than... At point "A" I measure voltage and put NTC in flame, everything is working ok till about 1.1v, and...

Hi all,
I’m new to the forum and could use a bit of help. My name is Tom and I have a problem 😅
I bought a MacBook Pro M1 and also got a second one for spare parts. The seller told me it had a small water spill. After opening it, I found four spots with corrosion on the board.
One of those spots has damaged components — I’m not sure if they’re capacitors or other SMD parts. I’ve already cleaned the whole board with isopropanol, which made the other areas look fine. But could those damaged caps be the reason why the MacBook won’t power on?...
