Re: GA-K8NF-9, should I bother re capping?
I say go for it as long as it has easy to find cap values. I looked up the specs on that motherboard and it still is relevent to todays technology. Just remember, if you're gonna do it, change all of em.The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.
Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.
I decided to verify that the batteries were... -
I'm using Xiaomi Router 4A gigabit edition as wireless repeater. It worked fine for 2 years or so, but last week, wireless started to disappear.
When I unplug/replug the power, it was working fine for a day/half a day or so until it freezes again.
After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:
Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during... -
Hey guys,
I have a SHARP LC-60LE640X TV that has suddenly developed an intermittent fault of flashing white noise patches (appears like an Analog tuner off signal) and then totally dropping out.
This model I believe is also known as LC-60LE600U or LC-60LE640U in other regions.
FYI, a long time ago I was a component level repair tech for all consumer electronics and IT equipment.
I'm a bit rusty but still have ability to dig right down.
I measured all power supply lines and checked them for AC ripple voltage. Noting any lines that exceeded about... -
Only 3 years old. Owner said backlight went out and burning smell. Didn't bother plugging in to check if had power LED. Just opened the TV rear and found shorted bridge rectifier diode on the backlight circuit on the PSU. SF26G (400V 2A super fast recovery rectifier link ) diode replace with SF26 (what I had on hand) Google AI said G = Green Components.
Burn looked pretty bad on the board but just was blackened carbon coating material. Scraped and cleaned off quite well and clean solder pad for the new diode.

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).
