Hi, we've got a problem with HP Omen 16-b0009na, ram been replaced, with no change, no liquid damage, I've tried to clean ram slots, no change. Any idea where to start?

Sounds still like a RAM fault. If you remove all ram - still the same error codes? Can you link a schematic (inside the dedicated schematic forum only)?
No screen on startup; 3 long beeps 2 short beeps - HP Support Community - 6979452 -
Two of the most common problems are loose ram slot pins and a corrupt bios.Comment

mon2 I don't have schematics for this model, while ram removed there is still same issue. (Bios I haven't tried yet, would check tommorow)Comment

Any ideas? Tried on different BIOS - Same issue.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
Hi guys
I have a B&O Omen laptop here. It has very specific fault symptoms, hopefully someone can give me some guidance
If I plug in a known good 180W third party charger the little LED next to the power jack on the laptop flashes red once, but the laptop will not start. It will not flash red again unless you unplug and reconnect the power.
If I remove the main battery (I can't see a cmos battery) then the led by the jack does not flash when I plug in the adapter, but if I press the power on button with adapter attached it flashes once white every time... -
(If anyone has a functional boardview file of FX505DV/DU that would be helpful)
(Had 3 problems, now just 1)
I have no experience or knowledge and usage of tools to repair devices besides the entire past 12-10 days of researching, watching YouTube repair videos and troubleshooting this laptop motherboard. ChatGPT was used as a guide to ask questions.
I used boardviews of mostly FX505GD-M, and some FX505DU, FX505DD. Used schematics of FX505DU.
I had originally intended to replace the BQ24780s first (due to previous battery removal while benchmarking) but I...
