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 all,
Re-assembling a Ionmax ION390 air purifier after removing the top LCD control panel, I seem to have 2 extra screws that I, for the life of me, cannot see where they go. I've taken a couple of pictures, buuuuut there's always that one picture you need, but you didn't take :/.
I know it's a long-shot but has anyone repaired this before would have an idea?... -
I'm currently in the process of replacing the LED backlight strips and during the midsts of getting the outer bezels off, in order to take off the screen, I stripped a couple of the tiny screws. Does anyone have an idea of the type of screw/size so I'm able to replace them? I'm just wondering if it's a specific non-conductive metal or not... a bit hesitant on going to the local hobby lobby, matching them up size wise, turning the tv on and then having it explode because it was the wrong metal lol
I was able to extract the few stubborn screws using a Dremel, and making a notch for... -
Hello.
I am in need of ordering replacement stand screws for a few different TV's...TCL / Vizio / Hisense. They all seem to be similar screws. I think they are M4 x ??. Does anyone happen to know what the most common size and length size is and where I can get them in bulk?
Thanks for any recommendations in advance. -
Trying to track this down. 3 boards all same problem. Rampage IV Extreme, Z87 Pro, Z97 pro. All boot and function correctly but all lose bios and time settings if power is shut off. If power is maintained, sytrms boot and reboot normally. I have verified cmos battery is supplying 3v to board. 8 pin bios chip has continuity to ground but no voltage to vcc pin. I assume that's the pin that maintains the settings with power to bios chip. How do I track this down? What voltage do these bios chips require?
