Re: ASUS G50V - Fried? Yeah, probably.
I'll look up some equivalents for you tomorrow.

Re: ASUS G50V - Fried? Yeah, probably.
Friend came by and dropped off a piece of plastic that was on the motherboard before we started working on it.

Fun stuff. Looks like they were both heated to hell and back.
Think that it's just that one / both were bad? I'm starting to wonder if that's the root of it all or not.Last edited by Flababa; 11-19-2010, 01:16 PM.Comment

Re: ASUS G50V - Fried? Yeah, probably.
I see a 5 pack for $15 out of Hong Kong. $3 seems fair when new from Arrow were almost $1 in small quantities. I looked through my collection of laptop boards and found several of the above MOSFETS including a few SI4392.Comment

Re: ASUS G50V - Fried? Yeah, probably.
The SI4392 on ebay have a different number set on the top than the ones installed on my motherboard. Honestly I don't know the difference, otherwise I'd make a decision about that now.
The 8170's are $15 for two, so I can grab those I guess. I'm trying to get this out of the way quick-like, so was avoiding Hong Kong. I've had this thing laying around too long.
Guess I was just hoping for a miracle. lolComment

Finally got the parts and the time.
Installed the new parts and bam, laptop will now POST.
Problem is, there's still a bunch of missing screws from the previous work done to it. Now I have to track those down.Comment

Re: ASUS G50V - Fried? Yeah, probably.
i have this same board and replaced both mofets and is kicking the power supply off on overlode i can plug a fan in to supply and it works so i know its good and i can pull 4 legs off 1 side of the mofet (dont mater witch one or side) and it wont set off power supply so im thinking im not far dose any one have any idia were i can go from hereLast edited by beastman2008; 12-05-2011, 07:04 PM.Comment

Re: ASUS G50V - Fried? Yeah, probably.
So, this seems to be a common issue with this model laptop.
I too have the power supply in protect mode when plugging it in issue.
On mine though, nothing is clearly burned.
Both of the mosfets on mine are TPC8107s that are on the underside of the board by the power jack.
One is just 'upside down' from the other.
I'm sure you can see in the OPs pics.
Wondering if replacing both of the TPC8107s there would fix the problem, or if I'd also need to find the Si4392 and replace it.
I know it's an old thread, but if people having this issue see this and we figure it out, it would seem to help many folks.Comment

Re: ASUS G50V - Fried? Yeah, probably.
I ordered a 5 pack of the TPC8107s I replaced all 3 of them on the board. It still goes into protect mode. I've visually inspected the whole board and I see nothing burned or cracked. The video card on this unit did not fail as I put it in another unit and it works fine. Only think I can think of is maybe a BGA failure on the north or southbridge. It doesn't work on a charged battery either. No lights, no nothing. Just protect mode on the PS which works fine on the other unit. Anyone else have any ideas?Comment

I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
This indicates an error in the communication between the outdoor and the indoor unit.
The outdoor unit is fine, so the problem is the indoor PCB.
The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.
Does anybody have the schematics of this board,...02-01-2025, 12:55 PM -
Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish.... -
Hi guys,
Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.
When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...02-03-2022, 11:14 AM -
Hi,
I'm learning electronics(already have some basics) by fixing a FH52M LA-J891P rev1B. It come from an acer nitro 5. The charger was defaulting upon pluging. The 19V rail resistance is 0ohm (I believe that caps screw my measurement). When i inject 5A, I get a rail tension of 1.3V, and 0.8V vcccore.
Except the cpu, I cant feel anything getting warmer.
I believe that it is normal, because the cpu is "eating" half the power I'm imputing.
I dont know if the cpu is fried, because I did not remove the big capacitor on vcccore.
I believe that if the cpu was fried,... -
Hi!
A friend of mine gave me a dead PS5 to look at. I am totally inexperienced, but when a damage is simple (i.e. failed DAP41 on PS4s, etc.), when replacing just the IC and the other very common failing parts of these consoles, problem is fixed. So I checked the voltage of the PSU - none was present. Model is ADP 400DR. I have a bunch of spare parts around, so first thing I did was to replace the IC DAP 053 (they seem quite expensive, so I put a replacement unit - TEA2016AAT. When plugged to the power outlet, 12V did come present.
So I reassembled the PS5 and pressed the power...
