Re: Digital Pic Frame LCD dead?
Thanks selloor but i opened them up and do not see anything bad at the naked eye, tested some components where the power enters in circuit board did not find anything, i wonder why this things just fail with no or litle use, one of them is not mine the person ordered it and it did not work out of the box he did not send it back within warranty i guess it's his loss, i think this is not worth the trouble,thanks anyway.Comment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hello, I removed the graphics card from my laptop and I want to heat it in the oven. What I want to ask is, is it okay to heat the card without removing the metal mounting frame on it?
As you can see in the photo, there is a plastic (black) gasket between the metal frame and the card. It sticks the frame tightly to the card.
I previously removed the metal frame while heating it, but it is quite difficult to separate it from the surface it is attached to. If there is no problem, I do not want to remove it.
What worries me right now is the possibility that... -
Some new tvs have an LCD screen attached to the outside of the frame with foam tape. These are "edge to edge" as they are called. I am trying to figure out how to reattach an LCD panel back up to the frame. The manufacturer used 3/16 inch foam tape along the top and rh/lh edges. I used a razor blade to separate the panel from the metal frame. The metal frame that the panel is taped to is 1/4 inch wide along the 2 sides and top. I completely removed the residue from the metal frame. There is some residue on the panel itself along the 3 edges, I removed almost all of it using alcohol and... -
Hi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
