    Changhong LED49YD1100UA Blinks power light 8 times

    Hi all, I have a 1 year old 49" Changhong off brand LED TV (LED49YD1100UA), when I went to turn it on the other day the power light gives 8 blinks and stops, it doesn't power on, not sure how to troubleshoot this but I am sure the 8 blinks is a code for a specific error. I've looked all over and it is difficult to find info online for this TV. Just wondering, has anyone run across this issue on one of these TV's per chance that could give me a rough idea of what this issue is? I'd hate to throw it away as I currently have it all apart and looking it over none of the caps look bad, it was purchased late 2014 for my wife and I as a thank you gift for some work I did for a friend.

      Pictures of internals could help....

      So many of these cheapo-chinese things around without seeing it--who knows what it is.

        Hi
        Did you figure out what was wrong? I have the same TV, also a bit over 1 year old and am having the same problem.

        Not sure if it's an easy fix or if I should toss it.

        Thank you for your help

          You will not get much help without uploading good clear pictures of the whole back side of the TV showing all the boards and pictures of each board. We do not have the TV in front of us to see what we are dealing with.

            You must have bought your TV from NewEgg on nearly the same day that I did because mine went out within a few days off yours.

            I opened mine up and saw a smudge of spot on the tconn board. One of the things you'll appreciate about Chinese market TVs is that they're alot easier to get into than their American market counterparts. If you see any carbon on a part, just match the model number and replace it. It worked for me and cost $12... As a bonus my insurer had written the TV off and replaced it.

            I ordered my board off of Ali Express... It is not the exact same board as one the one that came with the TV but is about 98% similar and it works.

            I hope you haven't tossed it yet. That TV is all plug and play on the inside and you can find everything you need on the cheap.

              I believe I have the same issue with Changhong LED50YC2000UA. The panel suddenly went blank, unpowered black. Turning the TV off shows the red standby LED. Turning on again causes the panel to temporarily power up (powered black screen) and immediately go to unpowered black with the standby light blinking 8 times. I removed the rear panel and looked at the boards, but was unable to identify what user Aleph says as "any carbon on a part".

              Here are photos of my actual TV components: https://imgur.com/a/AFzpTzL

              Any advice is very much appreciated!
