    Are you talking about the optical sound output jack?

        Absolutely not. The red light is the audio output in optical form, hence "optical out".

          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....

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          LG 55EC930V OLED - swich on swich of no screen
          by maxim2511
          My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
          Then I get an idea to take it apart and clean boards from dust.
          In side of Tv was not so bad, I take compressed air in can, and gently blow up.

          Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...

          Insignia NS-LCD019-09 issue: Power light turns blue for 3 seconds, the flashes red before going solid read again
          by cajoeg
          Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

          The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...

          by Pandemic
          Hi all, I have HP Compaq Presario CQ71 that only lights up black light on the screen, capslock button blinking when pressed. Its motherboard is "da00p6mb6d0 rev d op67". what do you people suggest I do? I am also having hard time locating the BIOS chip because there are many chips that is similar to BIOS chip around the CMOS battery. Can anybody please provide me the BIOS file and the location of the BIOS chip?
