You can replace every board in the TV and chances are it won't fix it. Like 95% of sets that don't have backlights it's a backlight strip issue, the backlight strips have failed and the power board is shutting down the negative return path because of over current. On a set this sie it won't be easy to do yourself but it can be done, you will want to use suction cups to remove and replace the panel, it's very fragile and the larger the TV the harder it is to handle, order 4 suction cups on ebay or amazon. Also view some youtube vids on how to do it.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts or search the site by type in the brand name of your set, at its search box at the right column.. It will be best to replace the inverter board as card basis.

Changing the fuse on my TCL ROKU tv model 55R613

The mains fuse is the little black T05 sized component called a Wickman Fuse next to where the mains power enters on the power board.
Always choose an identical fuse!

My TCL Roku TV has a steady light (standby mode) when plugged in but does not respond to the remote nor can I use the app. No sound or picture. What can be the issue?

Open the battery compartment and remove the batteries from the remote. Unplug the power from your Roku device and wait approximately 5 seconds, then reconnect the power cable. Once the Roku logo appears on the home screen, reinsert the batteries in the remote
