Re: Kdl 32m3000
I replaced the lcd driver board (Tcon board) but it didn't improve the quality of the image. Please take a look at these links of what the image looks like, maybe that will shed some light?

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

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,
I picked up a Samsung UN65RU8000FXZA 4k Smart TV a few weeks ago, in hopes I could repair it and get it working. It was purchased in Nov 2019, Samsung already replaced this tv by the original purchaser.
I have eliminated the main board and power supply, and back lights are working. It was cycling on and off when i got it, I disconnected ribbon cables until I pinpointed it down to an LED driver board, and with the suspect board or ribbon cable section, 3/4 of the TV will now stay on and it no longer cycles on and off. I haven't found any shorted capacitors... -
