Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...05-19-2024, 11:40 AM -
Good afternoon,
I'd appreciate help diagnosing my A2442 that's only taking 5v and 0a
This was my personal laptop and I had closed it at the end of a class and opened it in the next class when it just didn't wake up from sleep (The battery was charged). I connected a charger later that night and it booted right up but touch ID stopped working. The next day it did the same thing but never turned back on when I plugged in a charger.
I though the touch ID issue was weird but I'm not sure if that info helps.

I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...05-17-2024, 03:34 PM

Greetings, everyone!
Would need some help with this mini PC, the issue is - after turning on, PC starts, but there is no picture on the screen, no reaction on LED in external keyboard. Tested with another known good RAM. All voltages are present. Looks like BIOS issue to me, right? I tried binary from this site --> [URL]https://www.gigabyte.com/Mini-PcBarebone/GB-BXBT-1900-rev-10/support#support-dl-bios[/URL] ( version F9 ), but still same behavior. Note, I flashed only BIN file from that archive. Although, it says "1.0" in the linked site, but I have board with 1.1 revision....05-17-2024, 10:17 PM -
Good Afternoon,
This is my first post here so I apologize if I miss something.
I'm working on an A1708 that draws 20v and 0a with the board removed.
When installed in the machine, it takes 20v and 0.1a. The fan spins up and the trackpad clicks.
Some measurements:
PPBUS_G3H: 13.13v
PP3V3_S5: 3.3v
PP5V_S4: 5.1v
PP3V3_S0: 0.6v
Any help would be appreciated. Let me know if more measurements would help.
Thanks in advance

Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

Hi all,
I sent my [B]ProArt Studiobook 16 OLED (H7600, 12th Gen Intel) [/B]to the local repair guys to have a very simple DC in port replaced. I sourced the part myself on accessoires-asus (french company) after struggling to find the right part in the UK. It looked completely the same to the installed part from what I can tell. Originally the only issue with the laptop was a bad / loose DC connection, and so the computer and battery acted completely normal aside from a very poor connection that would fail at certain angles. After the repair was completed I brought it home and used...05-21-2024, 08:16 AM -

Hi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.05-20-2024, 08:45 AM -

Hi,
I bought a faulty A2289 for myself.
The USB-C meter was stuck on 5V.
After remove the board the U3100 was corroded and also around but quite light.
So I clean the U3100 and see R2834 in bad condition and its value was not good.
I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.
The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.
How mush current the board is supposed to take without nothing...05-19-2024, 12:20 AM
