i have an lg 37lc2d lcd tv. it would not power on at alll. i replaced a bulging capacitor at c208 which i later read to be a common fail site on the power supply board. now i have a green led that blinks about 10 times then goes solid green. no picture, no sound, no menu function. one thing i thought might be the problem.. i soldered the new cap by melting and piling old solder around the openings of the connections, so the cap is not coated on the end of the leads and its secured IN the board but not ONTO the board. could this be my problem? is it like splicing wires without making a strong bond between wires ultimately preventing power from flowing freely from wire to the other?

Hi guys,
I post my problem here because I think it could be a capacitor related issue (Asus support on this particular subject is non-existing).
So the computer is a Zephyrus-S17-GX735LXS-26T and the strange behavior is seen.
On cold start most of the time the internal screen is detected and a picture it works fine until shutdown, sleep or deep sleep.
Then the screen won't work for a long period of time.
If I wait 1 or 2 hours it work again most of the time.
When it doesn't work the batterie indicator blink 3 times white stop and the same schematic is repeated... -
I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.
To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.
I have opened the camera and I think there is enough room to add something inside to accomplish this:
The camera is powered by a 3.7V nominal single cell lithium ion battery.
So I need to connect another battery in... -
So the motherboard on my first build ever (which was 4-5 years ago) just went out, I believe its something on the 3.3v side of things, the VSB, about a week ago it wouldn't turn on, and I have gone through quite a few PSU's, about 1 every year, they lasted anywhere from 1.5yrs to 4 months, so I went and got another PSU, hooked it up and got nothing, frustrated I left it all hooked up and went outside to smoke a cigarette, when I come back in, its on and running.... I turn it off, try to turn it back on and nothing for a few button presses, after like 5 button presses it turns on and works perfectly... -
Hello,
I just came here to see if someone has had the same problem I have, and if he or she solved It, to know how to do It.
I have made a quick search for my laptop but I have not seen anything similar.
I have an old laptop, an HP Pavilion dm4-1065dx which takes a lot of time to be ready to start if the laptop has been unplugged for a while. It has no battery. The battery failed long time ago. It needs to be plugged to work. But as I said, It can take a lot of time until the charging led gets on, and I can switch on the laptop. I am using an external monitor... -
I have had these 70 watt high pressure sodium yard lights for many years now probably at least 15 years or more and there is a protection diode that after several years starts to go bad and when it does this it has momentarily shutting down the light and then a few minutes later it starts working again
This about the forth time I have fixed this one and you can tell if it the diode or not if it lights up and it only shuts down when the air conditioner turns on then it is the diode
If it cycling on and off constantly then it is the bulb itself that is the issue
