I have Skyworth E3000 Series TV, has been working fine but yesterday went to turn it on and screen is black. I can see a faint pictures if I hold a flash light up to the screen and the sound works fine. What can I do?
Hi @chodan , It seems as though there is a screen LED backlight problem. Either with the power supply to the backlights or the backlights themselves. Can’t find a service manual or a teardown video for the TV so I don’t know if there is even a separate power board or not. You would have to disconnect the power from the TV and remove the back cover of the TV to find out. Check what board that the power cord from the wall outlet is connected to. If that board then connects to another bigger board which has the different signal input connectors on it e.g. HDMI , coax etc. it is the power board. If everything is on the one board then it is incorporated into one. It may be easier to use a backlight tester - examples only to check whether the problem is in the backlights or the power supply. The tester can supply power to the backlights without the need for the TV to be powered on. There a lots of videos on YouTube that show how to use it and test the backlights and also how to replace the backlight LED strips or even individual LEDs if necessary. The LEDs are in series connection so one faulty LED can turn off a whole strip.
