ThinkPad T490 20N2000CSC NM-B901 no signs of life - short on 5V SMPS, ThinkEngine-3 hot - *speculations*
0I think ThinkEngine shorted first0%0I think 5V SMIC shorted first0%0I think something else happened0%0Attached schematic 🙂.
Laptop gives no signs of life. No fan and no CPU heat.
Think Engine BD4179MWV is hot on plugging in *AND* pressing the power button.
Discovered short to ground on VCC5M power delivery IC NB690GRP (5 volt line, not the high current VCC5M_PD) which is one of the ways that chip is powered. I'm puzzled.
Nothing else is warm on the board. CPU resistances are OK, 9V VSYS line is present from the BMIC. All misc and cables are disconnected.
What do you guys think happened? I've got two theories:

ASUS ROG STRIX GL702VSK no power issue PQ8901, PQ8900?
Hi,
working on a ASUS ROG STRIX GL702VSK 60NB0DZ0-MB1260 that does not power on. At the PQ8900 PIN2 (P_CHG_ACMOS_G_20) I am receiving 24.7V and PIN1 (P_CHG_ACMOS_S_20) 20V, however when I place the PQ8901 P_CHG_ACMOS_G_20 it drops 0V. I don't have the replacement mosfets ( N-MOSFET QM3058M6AC PRPAK5*6
UBIQ) however will any N-channel mosfet with similar parameters work ? I also found that PCI8703, PCI8701 are shorted. any help would be grateful.

12v PSU help please.
I have a 12v psu from a DJ lighting system and I can not seem to figure this one out. The board so far had a blown fuse and a shorted voltage regulator. After replacing those I get 12v out but hooking a load to it the voltage seems to bounce between 5v and 0v. I remove all the caps and checked those and replaced 2 that were only questionable. I know it's not the device I connect it to as I put 12v to it with my bench power source and it works fine....

Same problem with DELL EDC41 LA-G891P and DELL EDC50 LA-901P
Hi everyone, I have the same problem with two Dell notebooks. One has the EDC41 LA-G891P motherboard and the other has the EDC50 LA-901P motherboard. Both do not turn on and the processor also heats up a little.
In the coils there are 3.3v - 5.1v - 13v - 19v - 1.8 - 1.05V and 1.0V prime core
On both notebooks, if I press the power button the LED turns red and if I release the button the LED turns off.
What could I still check before saying the processor is dead?
Thank you

Logitech keyboard switching 2 keys
This has happened on three keyboards, so now I am assuming it is something in the machine but I can't track it down. Every time you plug in a logitech wireless keyboard it will immediately switch the "c" and the "v" permanent on these boards. There is no malicious software I can find, the board cannot be reset or put back. The very last one I tried was a MK 235 with the same end result. If you plug in a Microsoft wired comfort curve board, no problem at all. I have tried cleaning the system, deleting all boards from the device manager, updating the Logi software,checking MS...

Quecoo T12-958 soldering station - INVER error?
I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.
Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.
Any idea what the problem is?Last edited by spleenharvester; Yesterday, 01:39 PM.

As a foreword I'm relatively novice with component level audio gear repair. My amplifier stopped producing sound and I currently have no funds to buy a new one so I need any help to repair it. I know "no sound" is one of the most common problem but there were other symptoms so some of you seasoned repairman might able to pinpoint the stuff I have to check. I did download the service manual from manualslib the "no sound checklist" is a bit intimidating.
So i bought it working. First symptom: speaker protection relays on the audio board were clicking...7 Photos

Recommend a decent Multimeter on the cheap

- DC volts up to 30V
- Accurate Resistance
- Diode test (Beep mode)
- Frequency up to 200MHz
- Capacitanze up to 5000uF

Panasonic AG-1000B VHS player with bad picture quality
Hello!
I recently got an old VHS player from Panasonic and just for fun I want to try to repair this device. It is an AG-1000B portable VHS player from 1990 and it has a problem with picture quality in playback mode.
Picture in playback mode is very noisy and often loses sync but the still images are nearly perfect.
I want to know, is this something that could be solved by recapping or is the video head likely gone?
Also, what mechanism is this?
Any feedback is appreciated!...
