Lenovo G780 LCD Circuit Short

09-19-2023, 05:31 AM

Hello...

I've got my old Lenovo G780. It had a broken screen a while back and I replaced it with an aftermarket one. The aftermarket one died after a year (shocker) and some really strong plastic smell started coming from the laptop. When I went to open it up, I found a burned mosfet in what the schematics call the LCD Power Circuit, which I assume is the inverter?

I'm not sure if I'm supposed to link schematics but they're easy to find. The mosfet's label on the motherboard is Q80 with a part number of PMV65XP.

They seem to be on eBay. Should I just order one and replace it? Or should I do something else beforehand?

Thanks!

Help me find the short circuit on this WORKING Nvidia GTX1650

by aaronkatrini

Hi all,

Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

9th Gen Dell Optiplex Micro PC motherboard repair: Short Circuit?

by Geeker007

Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

I am new to electronics repair, so my queries could be naive but I am ready to learn.

So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...

Nintendo Switch lite charging chip heats up and does not short circuit

by fab13

Hello everyone

Small technical problem on a Nintendo Switch lite
Here's what I noticed: the USB port has been damaged internally, with a short circuit on the power supply line to the small fuse.

After replacing the USB connector, the short circuit went away and I can't see any other short circuit in the whole motherboard.

When I charge the console, it seems to be charging: I get 15 volts and an amperage of 0.450 A.

Then, after a while, the amperage increases to 1.1 A and the BQ24193 charging chip starts to heat up, as evidenced...

Short Circuit tester

by Tarot Superstars

Hello.
I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.
