Curtis LCD 4680A TV keeps reverting to AV2 source instead of staying on HDMI1 setting where I had it on. The TV is connected to a Dish Network receiver using HDMI1, I had this as my default Input Source. It is also connected to a Nintendo Wii on AV1 and a VCR/DVD player on AV2. All three were working just fine until 3 days ago. I switched from HDMI1 to AV2 using the side control panel on the TV. After watching our movie on AV2 I switched it back to HDMI1. Now every time it gets turned off and on it reverts back to AV2. I have tried the following and it still reverts to AV2 when you turn it on: 1.) Switched it back to HDMI1 using the remote as well as the side panel several times 2.) Reset TV to factory settings, several times 3.) Unplugged all components from the TV, Reset to factory conditions, Unplugged the TV from the Outlet and the Back of the TV, also turned off an on off switch it has in the back for 3 hours, then turned it back on I need it to default to HDMI1 when I turn it on. Please let me know if there is a way to return it to factory settings that will not result in the TV starting on AV2. Or if there is any solution to this problem. Thank You!!
