Re: LH70BVPLBF/ZA samsung 700DX2 power issue
As far as a kit i realize I'm on my own with it. There is actually a ton of room on this thing inside the casing to hide a power supply, a power supply of which based on my math will need to be 12v and at least 10 amps for the length as far as I'm reading I'll need at least 10 meters of led tape which is about 600 led's, and laid out horizontally I should only need 6 pieces at most. the tape I'm going to use has 5050 led's and from what I read I should use is coolest white possible, please correct me if I'm wrong about my choices and if my math is off. I do realize 10 amps might be pretty hard to find off the existing power boards to tap which is why I'm considering a separate power source, however I'm wondering how I could tap it in to be switched on when the monitor gets turned on.
And as far as pictures I'm in the gluing the middle LCD panel supports back on that broke off from being brittle so there's not really much to take pictures of at the moment.
Thanks for all the help guys it's really appreciated, my total cost involved so far is really only 20$, new ccfls would be 45$ for 10 through aliexpress and they've all got just about their life out of them. I could do the 10 but I can almost guarantee I'll be changing more out sooner than I'd like, it's a project that I'd like to just be able to put it on a wall and leave it when doneComment

Common LED strips aren't suitable replacements to convert a CCFL monitor as you might see bright spots in the image (each led) and chinese led strips aren't the most reliable option either.Comment

Re: LH70BVPLBF/ZA samsung 700DX2 power issue
I'm not really worried about hotspots in the pic, there's a ton of room to mess with positioning of the strips once they're all wired in now that the ccfls have been removed, my question is where can I find 12v at the needed 6Amps for this home made led "array". I bought a separate power supply for them just in case I couldn't find it but I'm not even worried about heat dissipation because the entire surround is aluminum so all the heat will be dispersed well, I'm more worried about safe operation and not having to do the hokey pokey to turn on the back light then the monitor, any ideas on what I would look for to wire the backlight into the on switchComment

This is what I bought to replace the ccfl's. 10 meters of the cool white 5050.Comment

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

Hello Everyone, this is my first post and I am excited to be a part of such a great community. I've been reading these forums for awhile and there really is some good friendly people here. No bashing and being rude like 90% of other forums Ive been to. Lets get to the good stuff.

Hi all,
My Samsung TV display recently stopped working while I was playing PS4 (no storm or anything to indicate a power surge). I could still hear audio through the PS4 but no display. The TV kept trying to turn on but would turn off after a second or two.
I tried the obvious troubleshooting steps like unplugging, replugging, trying different outlets and power cords with no luck. Someone on another forum suggested that it may be a power supply issue so I purchased a replacement power supply board but that did not help. I then disconnected the main board from the...08-31-2021, 09:32 AM -
I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the... -
I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.
Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:- Verified that all critical voltages are present:
- 3.3V and 5V are always present if DC is plugged.
- 1.8V on the BIOS chip is present.
- Checked the power button functionality:
- When pressed, the voltage drops to 0V, indicating the button is functional.
- Inspected the flex cable connecting the USB, audio, and power button to JUB1:
- Confirmed connectivity is intact, ruling out issues
