Hi, I bought a second hand TV/DVD combo (Matsui). It worked fine for a week but now when I turn it on all I get on the screen is a 5 minute countdown clock. When it gets to zero it starts to count down again for 5 minutes. Nothing I press on the remote control has any effect. I can't even get the DVD drawer to open now.
If anyone knows what I can try I would be very grateful.
