by NicktronicHi all, just curious if the BL_ERR signal is active high or low? TV has the 6 blink error code and I've changed the backlights as they tested questionable (4 strips tested - 203VDC, 203VDC, 203VDC and 175VDC). The new strips all tested at 175VDC. Now when I turn it on, it tries twice to come up and then the 6 blink code. During the this time the BL_ERR pin is high and drops low momentarily, then does it again on the 2nd try to boot (so Im assuming active low). The other thing is the backlight voltage ramps to ~280VDC from around ~160VDC and then back down as the TV tries to boot again. Does...06-03-2024, 07:30 PM

by GjacksonHi all,
got my hands on a Samsung UE60JU6800K, initially it apparently had a bunch of white circles on screen which I confirmed was due to loose diffusers when I opened the set up and found a mountain of them at the bottom. The person I got if from stored the TV unused for a lengthy period after this so when I got it the backlight was completely gone. I took out the strips and almost all of the LED's have a crack on the yellow phosphor form the center of the LED outward, the ones that don't have this crack seem to work still (Maybe due to humidity after a long period?). Anyways I...Today, 06:03 AM -
by Stigsolbjerghi again
this time its a mainboard from a mowerrobot, when i connect battery it shorts it, so the bms shuts down battery.
when take the mm in beepmode and measure from the positive to the negative battery terminal on the board it beeps shortly like 0,25 sec, and when i reverse the probes it beeps again shortly 0,25 sec.
when i mesure on the cap thats missing in pic nr 2, the bottom solderpath goes to the negative, the upper one is 1,2 ohm to negative is this a short?

by Arc717I 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

by danny1roHey guys, I'm new here and I'd like to say thanks for all the knowledge on this forum first of all.
I am learning electronics repair, been fixing GPUs and laptops mainly until now, and I'm slowly trying to fix desktop motherboards now.
I had a few successes until now, but I messed things up with one of my recent attempts, namely a Gigabyte H410M S2 with which I burned my test cpu.
I had identified a mosfet which was burned, removed it, cheched for shorts and I didn't find any.
When the new mosfet came, I put it on the board and checked for shorts again and didn't find any....06-08-2024, 08:38 AM

by DgeHi,
I purchased one of those units for a project and the BIOS is password protected. I was able to dump the BIOS (Insyde), it's 8MB. Tried various ways to clear up the pwd to no avail. Hoping someone can figure out how to bypass it.
Thanks!-

by titomno2Hi guys,
I currently trying to figure out why the laptop of my friend did not charge.
It is a Acer AN515-42 (Ryzen 5 2500U), I manage to make it works on AC and battery but no charging.
At first it was not working on Battery, I discovered that PQ201 was knocked off and replace it => work on battery precharged on another computer.
I also checked the small resistors between PQ312 and PQ201 and even if they are ugly values are OK.
My issue, when I plug the charger computer off, it drains 0.25A during few seconds with amber light on (charging) then amber light blinks...1 PhotoToday, 11:52 AM -
