thank you ,i have a problem with this ic tea 1716 in led tv power supply NO POWER, her problem is that it was exposed to high voltage, and I found the main capacitors swollen, I replaced them, but the IC heats up greatly, but it is fine because I removed it and tried it in another card and it worked fine. Where is the problem? Is it in the components surrounding the ic tea 1716? but which pins of ic responsable for overvoltge or which components must be change smd capacitors and resestors or all .

not necessarily a "repair" question.. but I'm working on a project with a LG LED 55 inch 55UK6090PUA. I got it free because the screen stopped working but not the backlights. I'm using it to make a Movie Poster backlit frame. Question. How would you go about powering just the backlights? I need to be able to dim them as well because it is REALY bright and I no longer have a way of seeing the settings menu obviously. Don't need to waste the power on the rest of the TV components. I'm in Clearwater FL and have the parts I don't need if you could use them. Thanks

My problem is that my tv from JVC goes on but only for a split second where I can see the JVC logo, then everything goes black. The blue power on led stays on but the screen is black. Yesterday the TV actually started after a few tries and after that I could turn it on and off but when I unplugged it and moved it to the tv room the problem was back. I wonder what could be wrong?

Did you check the two capacitors where the power connection for the LED's go into the EAX power board? Sounds like a leaky capacitor.

Have a Samsung 4k 6900 series that has one problem: A vertical grey bar, about 9 inches wide, at the extreme left side of the screen is present most of the time. Sometimes it flickers and goes off. The connectors to the TFT display and TCON board seem secure so is this a bad TCON board? NOTE: Rather than sending a tech to look at the TV Samsung said to scrap the TV and sent a check for a replacement. Can the TV be repaired? ANY ADVICE? THX Steve Morris
