Unfortunately….the TV Screen is bad. The LEDs are at fault.. It is nearly impossible to remove screen cover to replace the LEDs in any TV. When under warranty…we will receive a new panel (screen, once called the picture tube) and replace. Take boards out of bad TV and install into new panel. A new panel is as much as the TV $. I have seen many TVs with this problem, and is common to all sets now. Thanks for asking, Matt of Martins TV Repair.
I have repaired many of these. Unfortunately the LEDs are not operating correctly. It may be the LED board. But truly the LEDs are flickering because of a faulty LED. These units can have approxitimately 40 + LEDs. If one goes out….they all go. The only real poosible repair is to replace the entire panel (What you actually watch is the panel). You may have seen repair on line, replacing LED strips…that may be fine. This is very time consuming and can be a complete waste of time. Under warranty, ( year old or less) a new panel is sent. We remove the boards from your now TV, and place them into the new panel. I would consider shopping for a new set. Thanks for asking, Matt of Martins TV repair.
Another thing you want to try, in TVs with this issue. LVDS cables may need cleaning. These are the TAPE (CABLE) RIBBON you see to and from power supply to main board. The other RIBBON CABLE to the T-con board or the TV its self. Unclip these carefully and slide out. With a can of electronic cleaner spray a chamois stick. Clean the contacts at the end of the RIBBON CABLE (TAPE), and then the board contact its self as well. Thanks for asking Matt of Martins TV Repair.
