    campomatic tv secret service menu

    Hi guys
    i got a campomatic led tv labeled "32s1j" which have a back light problem: no back light.
    i opened it and did some voltage test ,the led driver deliver only 26 v which means that one led or more is fried.
    There is two led strips and each one contain six leds.
    i changed the fried led and reconnect the two strips and the problem were fixed, the led driver now deliver 70 volt when i press the power button and 26 v in standby button.
    i turn the tv on for three hours, after the led strip fried again!!
    My assumption is that the current delivered by the driver is to much for the led which caused them to fry(the led strips are not the original ones,they were changed by another shop before i got the tv)
    To solve the problem a friend of mine told me that i should access the tv secret service menu to change the brightness of the tv which decrease the current and increase the leds life if that make any sense ??
    But i don't know how to do that :-(

      You may be able to turn down the backlight using the On Screen Menu. It's the backlight you need to turn down as low as possible to reduce the strain on the leds and not the brightness.
      Willing to help but I'm no expert.

          Thanks dick
          but i have been told by an expert that the on screen menu is not the solution
          i need to press a combination of buttons to enter another menu.

              I have found that if Backlights strips go bad and you have to open the Panel, then replace ALL the Backlight strips with new strips. Repairing strips by replacing just the bad LED WILL fail again as the other LEDs would have taken some strain already. If you are changing ALL the LEDs on EACH strip that is fine dick_barton is correct when he advised to go into the Menu and reduce the backlight setting. Some TVs you can do it from the User Menu and some TVs you would have to go into the Service Menu by pressing a combination of buttons to access the Backlight setting.

                      How to access Vizio m652i-b2 service menu
                      by tusiime
                      The current main board on my Vizio m652i-b2 only has 1 of 4 HDMI ports working. Also, the coaxial port is not working.

                      So I ordered a replacement board. It boots up the tv, but the display is dark in areas, colors are off, etc. I have seen information online that a setting in the service menu may need to be adjusted. Have tried many ways to access the service menu using remote codes, but none work.

                      Can someone here provide the confirmed method for accessing the service menu on this tv? Thanks in advance!

                      QN55Q60R Service Menu Panel Help
                      by Storyteller12
                      I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.

                      I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.

                      I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.

                      the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....
