To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

by gbaicu51Hi all,
Looking for advice please, regarding those 2( film capacitor?? - honestly not too confident if are film capacitors). Short version of story : I bought a stagepass 500 active speakers, and found those components nearly blown. I know they are 1= L 125. Any advice where I could find them to buy, and also what else could lead to this fault?( I have a multimeter and soldering iron and I can get fixed if someone could give me some instructions)
Thanks all4 Photos-

by NagyeszHey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...05-13-2024, 03:05 AM -

by Mathias1xxXHello, I have a customer who updated his bios on his GT72-6QD Dominator G series, He flashed the newest bios (even tho it said first upgrade to v10) But now the device powers on, the fans are turning but nothing more, no image. I tried to download the BIOS from the website and flash that using CH341A Black (GD25B64CISG chip) but still nothing, can someone provide me with the correct bios to flash on the device? Thanks!

by Carm99Hi
I have a Citronic AC-1USB.
When I run a turntable into it and then try to record it. The volume is too loud and distorting. In the red. Mainly 12” Singles. I haven’t tried a CD into it yet. I’m wondering if there is any way to bring the volume down inside the unit itself. Change a part or two. Put a small pot somewhere as there are no adjustments at all in there. I’m looking for the schematic but not found one yet.
Heres the circuit board inside.
Cheers

by RunlincHi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.
I am left with a good image apart from the black horizontal lines that I cannot get rid of.
I cannot find anything on the buffer boards that has shorted.
Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.
Many thanks for your assistance5 PhotosYesterday, 07:40 AM

by jasko_jackerThis motherboard has two chips one is UC4 -> 16MB which contains the main bios without the me inside, in fact if
use ME analyzer to check, it returns (see pics) "file does not contain intel engine/graphics/indipendent firmaware".
The second chip is UC2 -> 8MB, it contains ME data (see pics) and other things like PMC. If there are problems
like power management or ME, the chip to be rebuilt is UC4 and not UC2. Anyone confirm this?
I unzipped the exe file via this guide on the official Lenovo website

by ritaloHello,
I have a MacBook Air 13 inches 2014.
I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.
I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.
Then I have to find this value in the file : $SVS because it indicate where is the password.
But I can't find the value.
I have attached the file

by E--ManHi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...5 Photos05-12-2024, 10:52 AM -
