I invested a lot of time on a lot of 470uf and up caps on this several years ago, but still it wouldn't POST. Is there significant likelihood that if I replaced all the 220uf and 100uf G-luxons that it would POST again? None appear to bulge or ooze.

Re: no post Pcchips T18 after recapping
Never had a PCChips T18, but I've worked on several M810.
When I got them, all would POST, but ran unstable (freeze). Replaced all caps, even small ones, on 1st board. It's stable now, tested with WinXP, linux, and NetBSD.
Seemed like a good start, so I replaced all caps on 2nd board too. Now it won't POST. Bah! OK, 3rd board, replaced about half the caps. Now it won't POST either. Double Bah! So of three boards, I fixed one and killed two. Maybe too much flexing and stress on the BGA solder balls? Dunno. Working on a BGA chip is beyond my tools and ability.
So I do not advise further effort on your T18.

Re: no post Pcchips T18 after recapping
I would remove few caps...
First on the list is Sanyo ME-WG 1500uF 16V (guessing), the most distant from inductor, speaking of vrm-in of cpu...
After that, would replace those Panasonics from vrm-out, with recommended (from this site) Sanyo

Would certainly wait for some other advices too....Last edited by tmiha71; 07-28-2014, 03:01 PM.Comment

My no-POSTing T18 has neither 1500uF 16V nor anything Panasonic.Comment

Re: no post Pcchips T18 after recapping
Than some pictures could help... If you do not know if boards ever worked, chances are very low to revive them... Pictures please...Last edited by tmiha71; 08-04-2014, 12:15 PM.Comment

Re: no post Pcchips T18 after recapping
I bought the board new, used it until shortly after warranty expired. I replaced the obviously bad and non-obvious twins with Nichicons and it POSTED several times, then refused to POST any more. So I replaced all the rest from 470uf on up with more Nichicons, but it's never posted since. I bought 200uf/10v Nichicons to replace the G-Luxons near Northbridge and PCIe slot, but wonder if it's seriously likely that would help, hence my OP. At this point, what would pix show anyone here?Comment

Hi, I'm working on a MSI laptop, Motherboard number MS-16W11, GF-65 Thin 10SDR-459US. Went to another shop because the screen was flickering, but it was working well on an external monitor. The LCD was ordered and the laptop was returned to the customer and it no longer worked. It was then sent to another tech (by the shop who ordered the LCD) and the EC (ENE KB9028Q) was replaced with a donor from another MSI board with different board number and no programming was done. It looks like work was done on PU6 (TPS51225) as well as one of the GPU mosfets was burnt (I removed all three GPU mosfets).... -
Dear reader
I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.
At the moment, I have selected replacements based on the following list of values:
3 x 470uF 10VDC
3 x 4.7uF 35VDC
4 x 47uF 50VDC
8 x 22uF 6.3 VDC
1 x 220uF 6.3VDC
5 x 100uF 6.3VDC

I have a dead FX505D, motherboard FX505DD REV 2.0 , the owner replaced the cmos using a screwdriver and he touched something on the board, since then the laptop its not starting, i have managed to see that U8800 (BQ24780SRUYR) charging IC is getting hot under a thermal camera , i have desoldered it but the laptop still doesn't power on, i also have no voltage at power connector on the board. I also replaced the U8800 but still no power. What should i check next?04-22-2024, 01:21 AM

Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.
To begin with, this laptop was dead-dead.
Now with replaced (visibly) blown components, i do get some progress; after connecting battery or main cable;- am getting white power led
- 5-long-flashes on CAPS Lock and NUM lock
- then, fan full speed
- CPU heats up some (smaller die PCH, does not)
- always constant black screen no matter what's tried
- no USB recognition
- no HDMI output
I tried... -
