Hi all I have a fuse 19" lcd computer display that seems to work fine but will not power off. The power switch do not function at all and the indicator light do not light up even when the thing is asleep?? Is there someone who can diagnose this problem?

Re: Fuse 19"
So, you have a monitor that is fully functional, but you can't turn it off because the pushbutton switch doesn't work. And the power led doesn't come on at all. Correct? And what fuse are you talking about? You'll have to post some photos of the entire power board top and bottom. Also, post a photo of the entire logic board. A model number for the monitor would be helpful. -
Re: Fuse 19"
As the two coloured LED does not come on at all, nor the switches work,,,my immediate suspect would be a missing earth/Ground, which would account for all the problems.Comment

Re: Fuse 19"
That is what I thought first. Then I realized the brand name is "Fuse" like this picture

Re: Fuse 19"
Sounds like the small PCB with the front buttons and power LED is not connected to the monitor's logic board.
Do the buttons for the OSD menu do anything?Comment

This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors
I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using
I am comparing them to a brand new one that I installed
The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well
I going to let it run for several days before I remount back on the wall next to the... -
Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I... -
Hello,
I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.
I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.
I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need.... -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
I have a very small float switch, I'm using in a very small tank. It only fits in one way. Link https://www.amazon.com/uxcell-Switch.../dp/B07DZ1J2GB
I want the switch to be open when the water is high, and closed when the water is low. Unfortunately it works the opposite. And since this switch is designed to be underwater, it's all sealed up, there is no taking it apart or hacking it up.
It will be driving a water pump, basic idea, when the water is low, switch closes, which turns on water pump, when enough water is in the tank, float switch floats,...
