Re: Delippo charger voltage question
The cord is about 4.9ft. (150cm) long 22AWG, the 5.75V voltage was measured at the farthest end (I cut the micro usb connector because I will not use it for charging purposes anymore), it didn't measure at all at the adapter circuit side, maybe because of no load but whatever.
I have something like this at home [url]https://www.aliexpress.com/item/32931253887.html?spm=a2g0o.productlist.0.0.65585f0f7j7A02[/url] and if I recall corectly it measured similar voltage not so sure about current draw, I think I also needed to do some wiring...

Delippo charger voltage question
Hello,
I bought this charger from eBay, the price was decent, not the cheapest one and I thought I bought a good quality charger for my tablet and maybe, occasionally for the phone charging also.
[U]The specs says[/U]:
Input 100-240VAC 50/60Hz 0.6A
Output: 5V 2A
Safe voltage output to charge phone, right? At least, that what I thought. Well, I tried that and trusting I bought quality charger -what could go wrong- I plugged in my phone and it instantly froze with black screen. I restarted it by pressing power button for 10 seconds and it turned...Last edited by tdr; 06-22-2020, 06:16 AM. -
Re: Some old 400W Akasa psu bulged caps and more
Hard to find the right smaller cap from my local store, they all are the same 1uF 50V low impendance but with different operating currents and impendance. How do you tell the right cap to buy? (click on the link and then on caps picture to see full specs)

Re: Some old 400W Akasa psu bulged caps and more
I just replaced 3300uF 10V with 3300uF 6.3V and PSU is still running fine.
That leaves one 330uF 16V to be replaced (small cap almost touching that big rail on the left side middle behind all wires so hardest to get to) this time I think I will not tempt my luck because I have only 820uF 6.3V left so I will look for proper replacement.
And the other one on the other side close to that big heatsink is rated 1uF 50V, should this need to be replaced too?
Also one small cap is on the child board...Last edited by tdr; 06-09-2018, 12:58 PM.Leave a comment:

Re: Some old 400W Akasa psu bulged caps and more
I already replaced both caps, first was 470uF 16V and second one close to it was 1000uF 6.3V and I replaced both with 820uF 6.3V Panasonic FJ caps.
PSU running fine. Nothing blowed up at the moment. Volts are kinda ok (except bios showing 11.75V on 12V line but Speccy reporting 12.5V go figure but those reading were the same before replacement too). Will not run anything important on this setup anyway.
Just to be safe I think I will order replacement together with the 3300uF 10V cap....Last edited by tdr; 06-09-2018, 05:36 AM.Leave a comment:

Re: Some old 400W Akasa psu bulged caps and more
So it is ok to replace these 2 Teapo SC 16V 470uF with 6.3V or 10V 1000uF caps?
I have Panasonic branded 6.3V 820UF FJ caps. Are these decent for replacement?
And I do not have 3300uF 10V cap, so I will need to order that one. I do have Panasonic 3300 6.3V FJ caps at home but my guess is 6.3V will too low to use there (tallest cap in the last picture) so I better go safe and order 10V or 16V rated cap.Last edited by tdr; 06-09-2018, 02:05 AM.Leave a comment:

Re: Some old 400W Akasa psu bulged caps and more
Never come to my mind that these big coils reaches high temp too, then maybe it is not good at all to use that psu at upcoming hot summer days when it reaches 25-28 degrees C in a room where pc is placed and instead just buy a new psu with cleaner design and more airflow inside. If only it was that simple...Last edited by tdr; 06-03-2018, 07:37 AM.Leave a comment:

Re: Some old 400W Akasa psu bulged caps and more
There are two big Teapo caps, larger one is 3300uf 10v, smaller one is 200uf 6.3v and there are two others hidden in the middle too far to easy reach and read labels. So I will replace these two ones with recommended caps. About the glue you mean that white-ish compound between components seen on the first pictures? If so, how to remove that hardened stuff?...Leave a comment:

Re: Some old 400W Akasa psu bulged caps and more
Above R56 is what I believe is my replacement capacitor and my bad soldering skills, it sure needs resoldering properly. I will check it out later and what's on the opposite side on the burned area.
Ok, looks like on the opposite side of the burnmark is diode below ZD1 mark. If I need resistor and diode replacement, what to look for? Are they common on spare psu parts or other board I can borrow from?...Last edited by tdr; 05-31-2018, 08:45 AM.Leave a comment:

Some old 400W Akasa psu bulged caps and more
This is some old power supply, it stopped working (didn't power on) several years ago. Bought new replacement. Recently I needed some psu for temporary built non important stuff. Bringed up this psu, replaced a few bulged caps. PSU is kinda working now, voltages reported from motherboard are o.k. (except some strange usb disconnect problems if more than few devices are plugged in), sometimes psu didn't turn on by pressing button but only manually connecting green and black wires.
But there is more. Looks like something was overheating there. On the board backside you can see burned...Last edited by tdr; 05-31-2018, 05:54 AM. -
Re: Problems with Samsung 740N monitors
I changed the bad caps and now I got the screen running but with some vertical colored stripes on the right side of the screen. Is that because of loose connection somewhere and can it be fixed? Thank you....Leave a comment:
