    Testing the LEDs inside an RCA 46C45RQ panel

    I was gifted an RCA LED TV model LED46C45RQ a few weeks back. TV will power on, but the panel just pulses quick flashes of light. I suspect one or more LEDs in the panel are bad. I've read that you can test the strip of lights by using the diode function on your meter. I was able to test two of the strips of lights and I believe I found 2 bad LEDs on the middle strip. One of the strips, however, will not illuminate the LED's no matter how I orient the meter leads, no matter what bulb I test. Is it possible that the whole strip is bad? Or is there something else that could be causing me trouble in testing? Short or open?

    Thanks in advance for any help you can provide.

    What does the meter display when you test the bad LED's?

      Finding the wrong part at a loooong led strip, part works fine, part flickers, all parallel...
      by edugimeno
      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...

      un60j620dafxza - Samsung No Display Problem
      by stylishconsultant
      Hi All,

      Need help.

      I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

      So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
      problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
      might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

      SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
      by triplefour
      TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

      tcon is built into mainboard.
      Only one cable goes to panel boards.
      there is a cable from one panel board to the other that links them.
      cost cutting measure that results in us having harder time to diagnose.
      removing the link to the second panel board allows TV to stay on with stable backlight but no image.
      used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

      Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
      by maneatingmonkey
      I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

      There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

      TCL 65S403 Backlight LED Question
      by tmhobadcap
      I got the TV from a friend. He claims that no image but sound from the TV.
      I confirmed that when shine a flashlight on to the screen, I can see the image. And this should be backlight problem.
      I open up the TV and found a few leds failed. And now I am ordering a new set of backlight strips for it.

      But there is something that I do not understand when checking the leds. I do not have an led tester. I only use a bench power supply. I first set the voltage to 3V and current to 10mA. I could not light up the led until I increase the voltage to 12V. I understand most...
