    Has anyone seen a Sony 55X900C led strip do this?

    The LED light strip along the bottom is randomly flashing off about 10-15 leds in a row. Maybe a bad led driver board? Or maybe some strange HDMI switching issue? Seems to get worse once the TV is on for a few minutes.

      Edge lits are typically wired in banks. One intermittent in a bank can cause that section to go out. You can lower the backlight level to see if it gets better but you should replace them all with new. LEDs wear and burn out just like light bulbs and your first suspect with backlight issues.

              Sonys typically don't have a backlight setting but backlight level appears to be set in the brightness setting. Most backlight failures I have seen in Sonys comes from putting the picture mode to Vivid which runs them at max.

                  Hi There!
                  I'm trying to help my friend who owns a restaurant be just bought.
                  He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
                  It's stuck using, I guess, the 2 sided tape that comes with the strip
                  The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...

                  Sony KDL-46HX850 Can't upgrade/update firmware
                  by dkneyle
                  Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

                  Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...

                  220v Led strip flickering
                  by adelage
                  Hi, I am installing a long led strip and I noticed that it frequently flickers slightly, it is not a strong nor regular thing, but it is noticeable and annoying. I have measured the voltage of the mains and it shows some fluctuations, it normally stays at around 226v, but often (every few seconds) drops down to 218/219v), and the flickering happens exactly at the same time. I have measured this at the counter and with every appliance off, so it's not related to the house electrical system, but that's how it comes from the supplier.
                  I know that the best solution would be to get a voltage...
