Hi, unfortunately Coby is not manufactured any longer. I have a problem not the same as yours, but I can't use my headphone when using my Panasonic Blu-Ray player. Have to use the sony digital surround sound. nothing comes through the Coby...If you have an extended warranty, I would call and have it replaced with another 40 inch brand..They can't fix it.I'm calling to have mine replaced or repaired...sorry i couldn't be better at helping..

Coby uses Samsung parts in their TVs such as the screen itself and the control board. My suggestion would be to try Samsung remote codes. I did this with a Coby 40" LCD TV

TV will not turn on. At first I coule get it back on and then it would soon go ogg again. Now I cannot get it to turn on. Now a No Signal comes on. Thanks for your help!

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

Contact Coby customer service by phone if possible to get the info--they likely will be standard ones that can be easily purchased locally.
