Mark this solved, my fix is working nicely...😃...
-
As far as I can determine, the component in question here, works with the other two 12 volt components to regulate the voltage / current to the second half of each LED strip. Therefore, the second half of one row will not work unless I can identify the proper component replacment. Also, a complete LED set replacement is likely not going to work without these component regulators on the LED strips, because the power supply will not start the second channel LED power circuit. Thus I cannot find any suitable zenor diode....

Thank you. I am aware of all the places to replace the entire set of LEDs, but since every LED string tests good, I want to get this one last strip working so I can test both channels of its power supply. Any idea if what the pictured component is?. Most new replacement sets, do not have these three components on the first half of each strip, so may not be compatible with my power board. Currently, only 4 of the nine led rows illuminate, with the 15th pin of the power board's LED connector showing ground. Ideas?...Leave a comment:

Part identification for Samsung UN50F6300
I need to replace the pictured small (3x2 mm?) Samsung LED strip component. I traced it the entire length of the first section of the strip. I assume it provides the positive voltage for the 2nd, shorter, plugged part of the strip. It's the one labeled 24V and scribed with 4E. AJ. Ideas for replacements, thank you. -

Anyone in here with knowledge of the components to assemble a USB / BT U2F security dongle? Or maybe phone app? -
Re: The 2023 Operating System Thread
OUCH..... I thought I used old stuff.
Daily driver is W10 22H2. I fix computers for my daily bread and W11 is a no go. Just more MS snooping and all the GD ads......just say NO. This has become nothing more than a personal info gathering machine... At least I know how to stop them from snooping in W10....I think.....??Leave a comment:

Re: ROG Front Base repair
I wish I had something that took those kind of pictures. What is it? Otherwise I have no clue what kind of thing you are talking about and probably nobody else can troubleshoot your issue until you post so MODEL NAMES AND NUMBERS for the thing in your pictures. Assuming that little lack dot it the controller, and then you should check the ribbon cables for damage. Assume that your MB plugs into that broken female socket, the socket is not the issue unless the contacts are damaged inside. It looks like to me the CONTACTS for that connector are on the side...Last edited by captainKKK; 01-08-2023, 05:01 PM.Leave a comment:

Re: Inspiron 530S - boot issue
Mark this one as a tribute to Badcaps forums as fixed. After tear down the PS the second time , I found a 2200uf 10v cap hiding deep inside, that was just barely pouching at the top and after replacing this 10 cent cap, it has worked perfectly for 10 reboots and 8 hours of operation. Never think that ONE bad cap will not fix your issues.Leave a comment:

Re: PC Win 10 random freezes help
I briefly read the previous posts. My first reaction is that it is overheating. Try opening the device manager and delete everything in there and not reboot when prompted and then get as far as you can and reboot and let it find everything again. Start at the bottom and do not delete the usb or the kybd or mouse until last.... Otherwise does EVERYTING work on your computer? Nothing flaky like the net adapter or sound or wifi if built in?Leave a comment:

Re: Dell xps 8940 bios master password request / bypass
You dont need any utility to clear the NVRAM, to do this all you need is
enter the BIOS and put on caplock, scroll lock and num lock and then hit alt
e + alt f and alt b system then reboots and the nvram is clearedLeave a comment:

Before you begin, follow the Safety Precautions When Working with Electronic and Electrical Equipment.
Turn off the computer and disconnect the power cable from the computer.
Locate the password reset jumper (PSWD) on the system board.
Remove the jumper plug from the password jumper-pins.
Power on without the jumper plug to clear the password.
Wait until the desktop is loaded and then shut...Last edited by captainKKK; 01-07-2023, 09:34 AM.Leave a comment:

Inspiron 530S - boot issue
The green light on the PS is on when plugged in and the orange light on the motherboard is lit but there is no response of any sort when I press the power button on the front. The led on the power button does not light and there is no beeping. What I have tried is shorting the PSU with a paper clip from the green wire to the adjacent black wire in the 24 pin plug and the PSU fan turns on and the CPU fan starts at max speed. With the CPU fan still at high speed, I remove the CPU four pin power connector (12v black and brown wires), from the motherboard and when I am testing the voltage diagonally...Last edited by captainKKK; 01-06-2023, 07:36 PM. -
