Re: badcaps in a ATX PSU
I carry only 6.3V caps (besides few 10V ones taken from MoBos), never had any problem. Unless you are deliberately using crap, there is no need to use 10V caps ever in ATX PSU.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

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).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

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.... -
Copying DMI information from an old bios to a new one is difficult for some members, often they have no experience with a hex editor,or some that have tried find it too hard.There is an option to make things easier for those members so that they don`t need to post their own bios backup for the DMI copying.
Experienced bios modding members can help by posting in other threads the DMI offsets,macro script generated by the software and a download link to the software at softpedia mentioned in this guide,or post your macros in the comments here with a link to the bios request thread .... -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.

I am dealing with this LA-G341P, which had heavy liquid damage around the Audio board, Battery charging circuit. I went and cleaned liquid areas and left the audio board disconnected.
It had blown PQ1900/02/3 as well as a trace on PU1900. I replaced all 4, and now it turns on and switches off. With a connected battery, it turns on and stays on for a while, even loading the system, then cuts off suddenly.
Charger only - without a battery, the PQ201/PD200 area gets hot. I can see the chipset and CPU also warm up for a second trying to pull up to 2A, then cust off....
