Sorry for the x-post, folks. At my wit's end to find this, been to the usual places.
Got an old Akay CT2590AT TV. The kids have managed to lock the first two AV channels. All I can see is the lock icon in a blue screen. There is nothing in the remote or menus on how to unlock. The manual is away in storage while we wait for new house to be built, so I can't check this. I'm down to only one working AV channel (AV3) without lock. The other two show up the image for a fraction of a second, then jump to this locked icon and nothing.
How the heck do I unlock this darn thing? Tried to unplug it from power for a day, nothing... The Akay website doesn't have any info on manuals or older models. Anyone out there with a manual or schematics for this TV?
Many TIA for any replies.
