I have a TCL Roku T.V. 55 inch . When I go to turn it on it has a light blue screen, when i disconnect the power wait a few seconds and plug it back in the TV reboots itself then goes to menu just like it should. Some times it will show the blue screen and sometimes it works just fine. What's going on with it, should i buy a TV repair kit maybe TCon board, power board or main board

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

SOURCE: Hello, I have a Samsung LN-S4692D.

You cannot test the T-Con bd with a meter. However if you have the luxury of having another same model tv, you can install the bought T-Con bd and see if it is good or bad. Since you said the Menu and channel flashses, then I would replace the Main board.

Roku 1 not working with remote


Check the condition of the battery in the remote. If no good, replace.

Reboot the Roku by disconnecting from power supply, wait a few seconds and re plug unit. Should work then since I have had my Roku lock up like this on 2 occasions.

If neither solution does the trick you just hope unit is still under warranty.

It's connected to my wi fi but it's telling me it can't connect to roku it says error code 011


The E011 error code is usually a router firewall problem. If you can turn off the firewall in the router when installing Roku that may solve the issue. This is not to be confused with the computer firewall in Windows which is left ON. When you go into SETTINGS/NETWORK your screen should look similiar to the attached picture. 25351243-jkwiv2v3rghcuytcwoewo3pc-1-1.jpg

My 39 inch tcl led TV power cord got abrubtly unplugged while watching TV. Plugged it back in and now the TCL logo on the start up screen stays there frozen. Many times already tried to unplug it, wai


Unplug the tv and hold the on/off switch on the tv (not remote) for 30 seconds. This should clear any power left in your electronic boards. Then plug it back in and try again.

TCL Blue Screen "No Media"


I HAVE FOUND THE ANSWER!!!! I just bought an TCL TV last night and was given the wrong remote. Screen was stuck on "no media" screen BUT I noticed that when I turn the tv on and keep pressing the menu button, the menu screen would pop up for a half second before the no media screen popped up again. So I knew it was able to access it. SO, it took a few try's and with no exact method I turned the tv on, waited til I saw the TCL logo and then simultaneously pressed the menu and channel up button repeatedly. It will open the menu for you and allow you to move between the input channels!!!! It WILL take a few tries to catch it but it worked!!! Your welcome!!!!
