good day friend. I have a Sanyo TV model DS20930 and I made the mistake of not marking the position of the card's plug and the 2-wire plug that goes to the screen is not fixed, connecting the plug and turning on the TV caused a failure. I disconnect the plug and the TV turned on with a blue image and a few seconds and turned off and on intermittently. I didn't want to invest it since I don't know if I could cause damage to the TV. What happens if I reverse the plug? I hope you can help me. regards
