Thanks, PQ301 is replaced with the donor & PQ306 re-installed. All mosfet mesurements are in the Mega ohms. Good to test? :-)...Last edited by Johndill; 11-18-2022, 07:10 AM.Leave a comment:

Sorry, that's a mistake, PR302 to ground is 30M ohms. :-)

Dell Inspiron 7567 LA-D993P odd charger issue
Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.
Here are the tested scenarios:
1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.
2. With the laptop off, plug in charger (LED says on) & the front charging...Last edited by Johndill; 11-16-2022, 11:09 PM. -

Re: APC UPS cap replacement
So it will run without it? :-)
Thanks for the uF and tolerence identification. :-)
I had a search but cannot find any of the same physical size so it may be proceeded by a smaller model perhaps?...Leave a comment:

APC UPS cap replacement
Hi, I have an APC SMX2200RMHV2U UPS and I'm looking for a replacement for this cap in the picture, it has melted I believe after a storm from what a friend said happened to it, it powers on and has "DC BUS Over Volt" error.
I've inspected the rest of the board and this cap appears to be the only issue I have found. I have removed the cap ready for a new one.
I'm located in Australia.
Also, can the board be powered on safely without this cap?
legs are 1mm size and about 37mm apart, leght 40mm, width 26mm, hight 41mm (excluding...Last edited by Johndill; 05-10-2020, 11:21 PM. -

Re: Laptop panel has green tint & purple lines.
Hi, thanks for your reply, as stated in the original post, "It has been tested on a known good system & found to be a fault with the panel & not the system or cable." :-) Could it be a cap on the panels control board?...Last edited by Johndill; 03-09-2020, 08:51 PM.Leave a comment:

Laptop panel has green tint & purple lines.
Hi, I have a laptop panel model LP173WF4 which has suddenly got a green/blue like tint and purple lines, You can see in the picture with MS Paint that it is not a white screen and you can compare to the white in the monitor in the background. Is this fixable & if so, what can I do? Thanks :-)
