I have purshased one year ago a portable dvd MP4 TV player from china. Last week suddenly the monitor has stopped working.When pushing the power button the lcd is just lighted (so I don't think it's a backlight problem) but no logo in the screen (nothing).I have to notice that the video output is working without any problems (by using rca cable from the dvd player to an external TV)but nothing with the lcd itself. I have tried all buttons combinations of the lcd and the remote without result.Any idea to fix this Please.} PS : Please bear with my english language.
Unfortunately there is no way for the average consumer to fix this dead screen. If the video outputs work fine then your TFT is dead. Or the input to the screen is already damaged.
