CY-VH055CSLV1V, screen black but sound available

@olathiza unless you have physical damage there is no need to replace the screen yet. Turn the TV to a program that has sound. Then, in a darkened room, shine a flashlight beam at an angle against the screen. See if you can make out shapes or silhouettes etc. If so you know that this is a backlight issue. If you cannot see anything, remove the back cover from your TV and take a look at all the boards for any obvious damage. Then remove the wire from the power board to the mainboard and see if your TV’s backlight turns on. If so you know your power board is onkay. If not then you have to use a multimeter and measure the voltages going from the power board to the main board. As you can see, you do want to make sure that this is truly a broken panel and not just a failed board.

If you do need a new panel it will be extremely difficult to find one. You need the model number from the back of your panel and then do a online search to see if they are available. IF you can find them the cost for the panel and shipping will most likely cost more than a new TV.

Once you remove the back cover take some good pictures and post those with your QUESTION. That way we can see what you see. Bilder zu einer vorhandenen Frage hinzufügen
