As I have seen on here that the new leds are going bad more and more often. I just wanted to see if anyone had tips to remove the LCD panel when replacing a led so the panel doesn't break. I have done up to 42" but even that made me weiry. I have a 50" to do and not looking forward to it

Re: Tips for removing big LCD screens
That's what I currently do for the 42"-46". It's hard enough to lift that. I might look into some glass suction cups.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.... -
Hi Everyone
I'm after some tips on how to remove a VERY stuck memory chip on an RTX2070. I am a beginner with this size chip so I bought an old non working GTX960 and I can remove and refit the memory chips to that with ease.
So far I have cranked my hot air station to as high as it will go (It says 450C but I have no way to confirm that but its hot... its a cheap ebay unit. And I have a large square nozzle and have tried smaller nozzles.) I cant get the solder balls under the chip to melt. It has taken some flux in under it but still wont move. I have chipped one of the... -
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... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
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...
