Re: reaseat cables ? line going down the left side of the screen
thanks tom i was hoping you would chime in
i was thinking after reading some post it was a buffer board , but when you say panel im guessing you mean in the screen itself ... probably my fault when i put the power supply in one wire i left off and i forgot the tv was on , and yep it arched on me i bet i sent it to the bone yard 
dam i paid 50 buck to fix the power supply yesterday lol i guess life lesson
yea its 2 pixalated lines flickering all colors like staticLast edited by passman; 06-09-2015, 08:13 AM.Comment

Re: reaseat cables ? line going down the left side of the screen
Yes, if you connect Va voltage to panel while it is live and the rest of the set is "dead" this can kill the panel.
It's a good lesson for the future... 2 thin lines... you got off easy.
I've seen panels, where the whole display is covered in lines (due to Va connection while live.) Ouch!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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.... -
Right SIDE usb.c port charges and transfers data without issue, two left side uSB c ports charge but do not receive or see data. Was liquid damaged, and repaired significantly and thought we were in the clear but appears this is the last issue that is rearing its head. I am trying to locate the RETIMER chip that communicates the DATA TX/RX but I cannot seem to find it on the schematic or maybe I am just so tired my eyes wore out lol. Any help would be great.05-29-2025, 10:35 AM

Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area.... -
- Prior owner tried a replacement main board. No difference.
- Samsung 2x red blinking standby LED = panel fault
- Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
- Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
- Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display
