    LG 42LV440 Two Fixes for One (Solid Red Light and Backlights Cut Out Repeatedly)

    I picked this one out of a dumpster. It had the solid red standby light with no signs of life when trying to power on. I ordered the repair kit for the main board from ShopJimmy. It consists of U18 and U21. I soldered them both in and hit the power button. The TV came to life but every five seconds, the backlights would cut out. I pulled U21 off, put the original one back on, and the set is now working fine.

    I used wick to clean the pads. I checked the pins with a 40x loupe. There were no bridges and no bad joints. I can only chalk it up to another faulty part from ShopJimmy. Though, to their defense, I didn't need the part in the first place and their description agreed with that.

    The model number is actually 42LV4400, I missed a zero in the title.

      Lithonia Lighting versus Light of America Compact Fluorescent product quality
      by sam_sam_sam
      I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

      I also have back when Light of America had these light bulbs available for yard lights

      The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

      While the Lithonia lighting fixture has all most certain bulb failure

      So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

      I have only had this light fixture for not more than a year if it...

      LG 65UH6030-UA lightning strike, no S/B light, no backlights, no OSD
      by DXseekerMO
      A few weeks back I got a call from a guy who said lightning had struck close to his apartment building, and ever since the TV would not come on. He said a total of four electronics items close to the TV were lost at the same time. He just wanted to get rid of it, and I'm always game for that!

      So finally today I had a chance to check it out. When it's plugged in to the wall there is no stand-by light. When the power button on the TV or remote are pressed the S/B light flashes three times and the Optical Audio light comes on.

      Shining a flashlight upon the screen reveals...

      RAB Lighting 30 and 48 White LED 9-12VDC Blinding Light Bars—> Very nice light bar
      by sam_sam_sam
      I bought these LED light bars from Electronic Goldmine surplus store online

      These light bars are the nicest LED light bars I have ever seen in there online store

      I read the description of these light bars and said yeah right there bright at 9 volts
      Let just see if this is the case or not and just how bright is bright because I bought some of there light bars that they said were very bright and were ok but I would not say they were as bright as they claim

      But I thought I would give these a try only because they had both light bars on sale as a bundle...

      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...
