Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...05-05-2024, 06:20 AM -

Dear forum,
I'm stuck with this old TV unit.
PSU: 17PW04-1
MB: 17MB62-1
Symptoms:
- Blue LED constantly blinking when connected to AC.
- Only sigh of life is beeping when touching the capactive buttons on the front.
Diagnostics so far:
Checked the PSU output voltages:
12V present
5V present altought its only around 4.2V
3V is present measured 3.4V.
I check TP 202 which is for the short circuit protection: 0.606V on diode mode
Since I met with some vestel models before with similiar symptoms...05-03-2024, 03:18 AM -
Hello. Coming to you from the laptop forum. Have a client with the Fortinet 50E that has 320 Mbps as internet input speed but only 20 Mbps output on each and every downstream port (using FAST.COM to benchmark).
Reseller is stating the Fortinet is 'worn out' which does not sound logical at all unless the flash memory is 'worn out'. They, of course, want to sell another + onsite installation fees.
Can anyone share feedback on this unit? What can cause this sluggish behavior. From our knowledge, this device is snooping on the traffic to halt viruses / hack attacks, etc....04-24-2024, 12:51 PM -
Hi,
I'm currently experiencing issues with my Dell Inspiron 5415. Initially, the laptop would sometimes fail to boot, with the keyboard backlight turning on but no display on the screen. After repeated attempts to power it on and off, it would eventually boot up and function normally.
To troubleshoot, I removed both the main battery and the BIOS battery, but now the laptop exhibits a different issue: the fan runs at full speed, but the screen remains blank, and it doesn't boot up.
I suspect there might be a problem with the BIOS, and I would like assistance...Today, 05:13 AM -
[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]
While wall mounting, I mistakenly picked a screw 0.5cm too big than the clearance and damaged the trace and one of the part (a capacitor, I think) on the board. Images attached.
Is this repairable or will I just have to get the entire board replaced? Please guide about this.[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]

I am still new to this, so I might sound brainless/ignorant in parts of my description/questions, since I have a lot of gaps in my knowledge, but I will do my best.
The laptop is Lenovo Legion Y540-15IRH, and the motherboard model is NM-C221 Rev 2.0 (Schematics and BoardView can be easily found). To save time I have the exact problem in the laptop as the one shown in this video:

Hi guys,
A few days ago i asked a real hard question regarding plasma tv's but nobody could respond. I need to ask if anyone has replaced this IGBT with another type that actually worked.
The industry is awash with fake chinese knock offs.
I am so frustrated.
Kind Regards

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.
When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...Yesterday, 01:30 PM -

Hello everyone, Due to a bad bios flash this Omen has a weird issue.
In the BIOS it says the ME version is 0.0.0.0 and when I try to update the BIOS it writes the bios region but when it reaches the firmware and ME it says it failed.
Tried HP USB recovery way and nothing worked.
I am kinda stuck, the main problem right now is the laptop would boot within 5 mins until the ME drivers load in windows and all works normally....Today, 03:02 AM -
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.05-07-2024, 04:34 PM -
Hello,
This special tool from Apple is used to recover data from Macbook A1706. I've been using it for a while but it stops working. When connecting Thunderbolt 3 between the tool and working Macbook, Macbook should prompt "new device detected, allow or not"... but it doesn't.
Has anyone ever experience this ? It's not a cabling or power supply issue, some IC have stopped working but not sure which one. Probably the one that manager thunderbolt 3
Thanks
