20 Most Recent Coby 40 TFTV4028 LCD TV Questions & Answers

Check the audio setup menu on Tv, the sound bar input selection, and try a cord from the headphone jack to the sound bar, if you haven't already. There should always be 2 channel stereo at the head jack unless it's turned off in tv menus. I see the owner's manual is very poor.

I'd add something to this. We had the same issue with a 40" coby. We'd declared it dead and after a few days turned it on again to show the problem before trashing it. The TV came on. We've since learned that there seems to be a HDMI handshake issue related to this tv. If you turn it off with HDMI devices still sending a signal, it will periodically return to this point, and take a day before it will turn back on (I guess until the caps are fully drained.) If you turn the TV off first and then devices however, this never seems to happen. Dunno if this is the same for others, but I'm curious

If you did not purchase an extended warranty, or if the credit card you used to buy it doesn't extend warranty, I'm afraid you're going to be out of luck. If HH Gregg isn't backing you up , i would not buy anything from them again.
