by mikkele86Hello.
got this Luxman R-5045 vintage amplifier which need a good repair and service.
finally got i started up and started to check voltages.
My issues is that the voltage measured is 3,5v to 4v higher than whats stated in the schematic.
Meaning voltages like +9v is like +13v
and +31v is measured to 34.6v which is really close to the capacitors rating +35v
I measured the voltage before the rectifier and im measuring 27v
did a online calculator and it showed i should actually get +36v after the recifier :/
So my question...Today, 07:18 AM -
by madjid911hello I have an acer nitro 5 model N20C2 (motherboard FH51M LA-J871P rev 1B) which does not charge, it turns on perfectly but when I plug in the battery, we see the charging indicator and the charged battery logo but it turns off a few seconds later, and there is no way to turn it back on, you must then disconnect the battery and the charger. If I turn it on without the battery it works fine.
I changed BQ24781 but the result is the same, I put after BQ24800 the same, I then checked all the resistors and mosfets, everything is ok, I bought a new new battery but the result is the same...Today, 07:58 AM -
by aaronkatriniHi 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...04-18-2024, 03:15 PM -

by ryogadan78Hi guys, I have this 2011 iMac A1311 with a strange problem.
Most of the time, when I plug in the power cord, the first of the 4 LED's turn on, but when I press the power switch the LED turns off and iMac won't boot up.
Sometimes, when I unplug and plug the power cord back in, iMac starts up correctly by turning on the 4 LEDs in sequence.
I have already tried a new power supply, but the result does not change. Do you have any suggestions?

Hi All,
Laptop: ASUS F15 TUF Dash FX517ZC-HN114W
Context: When I was out the house my partner hard shutdown laptop while BIOS was updating, so my son has no working laptop now. Also as a result I know the BIOS on the chip is messed up so I can’t extract it using the ch341a and use it to perform the method explained on site to modify an update downloaded from the ASUS website to get the BIN to flash.
If anyone can help with a BIOS BIN/ROM file for this laptop, I would be forever in your debt! Thanks if you can help!

by mikkele86hello.
I came across this thing and im not sure what it is exactly, I have never seen such thing before.
I know it gotta be some kind of diode with Drain, Source and Gate1 and gate2
It resides in AM/FM module and im measuring 200ohm across D and S.

by unimatrix93Hello everyone,
I'm trying to fix a small LG TV with wierd issue.
So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
The BL turns on, the tester shows around 80V. So the led strips are okay it seems.
Now I started to suspect the BL driver IC which is a MP3378.
I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.
