it's on top side of PCB, now from this point, we need huge resistor, more than 100K ohms and connect it between this point and ground, voltage will rise till about 15V then OVP kicks in.
Merry Christmas fellas

Re: Another PS3 PSU mod
Two chips are M34509G4 and LSSK87
first one is SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER,wtf?

it seems that this is some kind of PWM..Re: Another PS3 PSU mod<br /> <br /... kind of PWM..Re: Another PS3 PSU mod

Another PS3 PSU mod
I have another PS3 power supply LSEB1226B1 model.
Some time ago, I have successfully modified output from 12V to 13.8V
[url]https://www.badcaps.net/forum/showthread.php?t=33197[/url]
With help of members,it was really easy to do.
This supply is a little bit different, there are four photocouplers just like APS-231, but I did not find three pin regulator which is connected to "12v reg" photocoupler like in APS-231 model before.
Please see the pictures.https://I have another PS3 power sup... /> Some time... -

Samsung HT-DM150 sub output was shorted,need help
My sister was listening music on my home theatre, after some time I saw that poorly insulated wires on subwoofer output had shorted and from then subwoofer output is distorted after I turn volume to about 15 and more (70 is max so it's 15 is really quiet). First thing to do is check and replace output transistor, right??... -
Re: How to remove protections from SG6105?
Isn't there a way to disable it completely as SG6105 is TL494+ two 431 in one chip.
I have already removed 3.3v and other components and I don't want to solder it back
TL494 is very simple, just unsolder a few pins(13, 14 and 15 i think) from board and protection is disabled..Leave a comment:

Re: Seasonic S12II SS-430GB strange sound
Problem fixed, I have removed that glue or whatever it is from capacitor and re-soldered it and sound magically disappeared, it's still there but very quiet now, you can still hear it if you stick you head in PSU
Anyway, thanks for your help

Re: Seasonic S12II SS-430GB strange sound
Ok,after more research I have found that sound is coming exactly from this part(yellow in pic) there are two varistors(?) and a capacitor(?)
When I play games sound stops..

Seasonic S12II SS-430GB strange sound
There is like quiet hissing sound coming from PSU, it is 3 and half years old, capacitors looks like new, sound is coming from highlighted area on this photo
It's very annoying
It's not like high pitched noise, it's something different.... -
How to remove protections from SG6105?
I want to remove all protections from SG6105 powered ATX PSU,
I have removed all wires except +12v and I will use this PSU for powering 12v stuff
I want to remove protections and everything because PSU won't work without proper voltage on vsense pins. -

Re: Broken Philips 26PF9956/12, worth buying?
Technicians are s***bags here in Croatia, they will charge you like 100 bucks for one RAM module replacement, and they will say that motherboard was faulty and they replaced with new one, right, but almost everyone believe that... that's why I'm here asking for help and opinions, hopefully one day I will help others.
Maybe mainboard isn't the problem, technician is....Leave a comment:

Re: Broken Philips 26PF9956/12, worth buying?
What about this, owner says that there is only backlight when TV is connected to power outlet(not turned on!), remote controller doesn't do anything, he was in service and been told that mainboard needs replacemet (some chip on motherboard)

Re: Broken Philips 26PF9956/12, worth buying?
I know, I asked him for better pic, waiting for reply.
why?
This should be an FET on aluminium heatsink, right? and maybe burned transformer down?
BTW, this was unsoldered in service, not by owner....Leave a comment:
