The most common failure in this series is the SB.(FW82801FBM)
It is best to replace with new oneComment

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 got a request from a friend of mine to have a look to his amplifier. When switching on "OVERLOAD" was displaying, however from time to time, message disappears and protection was removed.
I took some time in visual inspection (no bold caps, no solder joins, no burnt components neither hot burnt areas). I took some time to measure transistors and diodes. Everything seemed ok.
I realized that when OVERLOAD was on, pin 13 on IC601 (RSN307M44A-P) measured 5V. From time to time, when Amplifier was not protected pin 13 measured the right -1.5V
(Pin 13 goes through...11-18-2024, 12:39 AM -
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... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
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...
