The power supply could be failing. It starts but is unable to continue operating.

Most likely it's a capacitor fault.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the TV and be able to use a soldering iron. If this isn't you then take it to a repair shop.

Unfortunately, your QWERTY keyboard remote is only for input to the TV. You cannot use it as a computer keyboard and mouse.

You can use the Logitech MX Air Mouse and a Bluetooth keyboard if you want a quality solution. I have a Gyration Media Center Remote which I love but they don't make it anymore. You can search eBay for that if you're interested. You can also try this but I wouldn't have high expectations.

sadly we can not fix this problem not knowing how or what needs replaced usually costs perhaps twice as much as having it done by professional repair shops

Look in the manual for Reset instructions.

The reason for the thick black line is that the screen is receiving no information to that section, either because the screen itself has developed a fault or the processor is not supplying to that portion, either way Im sorry to say the item is more than likley a uneconomical repair.

I have the exact problem. Already changed main board with no result

Unlikely. A new set of batteries is an easy test, but if you have no picture, how will you know. Or do you mean the On light doesn't work? If it works fine started manually, then if new batteries don't work, you need a new remote.

Replacing the power board can be complicated; both the method you use and the model number of the board will vary from television to television. However, it's still a fix that anyone can do at home with minimal experience.

You will need:
  • A soft cloth or towel to protect the television screen.
  • A Philips-head screwdriver. The size will vary based on the size of your television.
  • A container to place all the removed screws in.
  1. Lay the television face down on a prepared surface.
  2. Remove all the rear screws with the screwdriver.
  3. Find all of the fuses on the television. Most have five.
  4. If any of the fuses have blown, replace them. A blown fuse can often be the source of the problem, rather than the board itself.
  5. Locate any wires that connect to the power board and remove them.
  6. Remove the screws that hold the power board and remove the old board.
  7. Place the new board into position, then carefully screw it into position.
  8. Reconnect all of the wires and cables.
  9. Replace the rear cover of the television and secure it.
  10. Plug the television in and test if the repair worked.
