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.... -
My Yamaha MOX8 synthesizer recently developed two issues.
Firstly, after booting up, it operates as normal. However, after about 5 minutes, the sound starts to get distorted (broken up screeching sound) almost like putting it through a guitar distortion pedal. After a while, the distorted sounds will go away for a while and comes back. At times, the synthesizer will also freeze I need to power off and on again.
Secondly, when powering off and on again, there will be times where the synthesizer will freeze during the boot sequence (freezes at the MOX8 Opening Screen),...11-07-2024, 03:28 AM -
Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
Hi,
Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.
I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.
I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)
Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)
Anyone... -
Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but...
