      Samsung UE46F6400AWXXC not powering on, standby LED off
      by UltimateNeutrino
      Hello, since yesterday our Samsung UE46F6400AWXXC no longer powers on, with the standby LED off. It turned off when someone attempted to clean it, not sure if related. A few days ago, there was a similar issue, but it was solved after unplugging and replugging the power. Additionally, another user of this TV reported issues of the screen turning off randomly, which were solved changing the channel.

      I originally suspected the PSU, but if the mainboard is unplugged the PSU relay closes and the backlight turns on. It's only when the mainboard is connected that the relay doesn't close...

      Sharp LC-65N7004U / 65A6100M not powering on
      by vizi0n
      Hello Badcappers,

      I have this tv that does not turn on. There are 2 model numbers on it : LC-65N7004U and 65A6100M.

      When powering on the tv, the Sharp logo briefly appears with a dim S, and the tv turns off. While the Sharp logo is on the screen, the power light will blink 6 times (the last blink being very very quick).

      I suspect a bad LED driver, or bad LED(s). Do you have any suggestion on how to troubleshoot this ? I have ordered a LED tester and should be getting it next week

      Here is a link to a video showing what happens:

      I have read through the Basic LCD TV and Monitor troubleshooting guides.
      https://www.badcaps.net/forum/showthr...956#post305956, I am no ELEC engineer but can use a multi meter and soldering iron

      In the meantime I could not see any damage to any caps on the cold side of the power board, so I have replaced all of them.

      Unplugged the power connector on the board, I plugged the power cable in waited...

      Sharp LC- 58Q620U - Standby Light, No Backlights or Image
      by Tecc1229
      Hello, I have a Sharp LC- 58Q620U 58" LED 4K TV.

      When you initially plug the TV into the 120V outlet, I get the initial standby red LED light. After you press the power button the red LED goes out and no other lights come. There is no backlight flash, nor image on screen. No audio with HDMI source plugged in, nor does my laptop detect another monitor plugged in. T-con board makes a clicking sound with or without LVDS cables hookup or off.

      My first thought was that it had a faulty PSU. Reading voltages, I was getting a swinging voltages from the DC output from the...
