    I have a SOVA 27 inch tv and the same problem! I took this tv to a repair shop and they couldn't find the part anywhere to fix this tv! My tv sound plays fine but no picture. The so-called "Check the power supply proper voltage supply" response is lame because it doesn't address where or how to purchase a new one, let alone how to fix it. Hey what are we supposed to be checking?!

Sounds like backlight is dead. Shine flashlight on screen. Can you see video slightly. Replace inverter or some sets have inverter as part of power board. If led set replace led driver board. Also that may be part of power board.

You need to replace your backlight inverter.

Check that all voltages are coming from the power supply as they should. The power supply will be stamped with the correct amounts, and you just read with the multimeter to confirm.

After those check out ok, you will need to replace the inverter to "light" your screen again.


You can hear sound because the tv is ON, but the inverter isn't lighting the screen!


Hope this helps, please rate!

No data is sent to the screen


When the screen goes completely black, shine a very bright flashlight closely at the screen. If you can see the image, then the most likely problem is that the backlight inverter has failed.

The inverter is a circuit board that works like a flourescent light ballast. If the inverter fails, there is no backlight, and the screen is black.

Since the invertor is a high-voltage component, I would also listen for any unusual sounds associated with the failure: e.g. buzzing, whistling, popping.

To rule out some sort of connection failure, see if you can recreate the failure mode when using the TVs internal setup menu. The setup menu does not rely on any external inputs....of course neither does the volume control or channel indicator on the screen.

No Picture. Sound is OK!


That type of problem is becoming all too common with plasma and lcd flat screens 32" and above. There are two boards inside the plasma tvs that are called the y-sus and z-sus boards. From my experience the z-board has been the most problem producer with that no picture and sound ok problem. However, the one issue here is that the power to the to the y board goes through the z board. Most techs I know recommend replacing both. The reasoning being that whatever caused one to go bad would also weaken in some way the other. I am not fond of this type of thinking but since I do not have the tv in hand to take signal and voltage measurements I would start with the z board. On the internet you can probably find those boards and through e bay at a good price. They are not hard to spot once you take the back cover off the tv. The y board is usually on the left and the z board on the right. They have like 6 to 8 screws holding them in and three or four connectors that are keyed so you cannot plug them back in wrong. They are also clealy marked on the board itself and usually with a white sticker of some sort. New these boards can cost from $100 to $200 depending on the source. Shopping around you can find it worth fixing in my opinion if you can replace the board your self. Always disconnect all power when you take that cover off. Good luck and God bless. Roberto

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.
