  1. LCD Flat Panel Displays
    Hi all, I have a Sony KDL-70W830B 3D TV where it turns on, the front LED flashes 4 times, then it shuts off. According to Google searches: It displays the menu and even the app selection screen briefly (< 5 sec) before it turns off, so this tells me that the LCD hardware itself is fine (I...

    Hi. The LED Backlight Sync- What Does This Do? Is It Important If You'll it as 2nd Monitor/extended monitor only? This is a cable in the iMac that can do Target Display Mode (Late 2009 iMac). Thank you. God bless, Proverbs 31
  3. LCD Flat Panel Displays
    Hi there, I have a Samsung UE46F5500. I have both backlight and sound. I see a grey glow in the dark and also white spots visible from the rear vents. The TV LED light flashes red when I turn it on (can't remember if it did this before the fault). No burnt or damaged components/capacitors...

    Hey fellow A/V geeks. I have a quick question for those of you who sell or otherwise deal with Sony TVs on a regular basis: Have you noticed an unusual number of product flaws and defects this year? I have sold Sony products for nearly 10 years, and generally they have been go-tos for me when a...

    I have Samsung LCD TV 32 inch Model No LA32E420E2RMXL. It suddenly died yesterday. As you can see in the pictures, the backlight inverter use SEM2106 IC and i cant find the datasheet for it. The inverter balancer board is confusing for me. In every CFL connection ive seen, theres always two...
