hello! It turns on normally, but when the user/password window exits there is no longer any video on the macbook screen, there is sound, I have a backlight because it turns on and you can see the apple. So when I connect the external monitor I have video on both screens and when I disconnect it it disappearsComment

Hello, everyone!
A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,... -
Hi there!
Someone gave me their old monitor, it's Dell S2715ht.
The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs... -

Problem description:
Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders... -
Hi everyone.
I have the following problem.
I have a Grundig GV-250 VCR which has not been used for over 10 years. When I turned it on, the fuse of the PSU burned out, after being replaced it burned again, I ended up verifying that I had the bridge rectifier and the mosfet in short, I ended up replacing it, and I replaced all the electrolytics of the PSU. However, it started to behave strangely, as I will show you in the video that I will attach as a link.
In short, I ended up replacing all the ICs on the power supply CNY17G, TDA4605, TL431, TDA8137, TL082CP, AN3824K, L2720,... -
Hello to all,
I have a problem with monitor that is delivered together with CCTV system.
The monitor appears to be completely dead, there is no LED power diode and it doesn't react to pressed power button.
I have disconnect display and check many components on the power supply part of the board. There is no anything obvious and monitor is about 3 years old. There are no bulged caps. When measuring voltages on the output connector to VGA board I can measure stable 14.5 V on 12V pins and stable 5.07V on 5V pins. So I assumed that this part of the board is OK....
