I got a coby 19' flat panel TV 2 years ago and NOW i have no picture what so ever! i have sound but no picture. I turn on the TV and all i get is a grey screen with different color lines. is there anyway to fix my coby tv?!?! PLEASE HELP
I'm not certain but it sounds like there is a loose video cable in there...if you are able to, take the tv apart, and literally push on all of the connectors and cables to make sure they are not loose. The main video cable may not seem to be loose, but once it is making contact again, it should clear that mess up. Just look for cables running to the main screen and pull them off and put them back. Then put the tv back together again and see if it worked...it usually does. why does this happen? Some blame it on dust, others blame it on quick manufacturing processes...whatever the case, the cables become slightly seperated from the controller board and that happens...it also happens to computer monitors too...Good luck and take your time. If there are a lot of screws and things either take pictures of where they all went or write it down. I like to make a diagram on a piece of paper and tape the screws on the diagram to show where they went.

I had the same problem and fixed it by replacing the control board. It's a little nerve wracking, but required only simple hand tools. If you'd like to see detailed pictures of the repair check out my blog.

Sounds like the digital control board, 6871qch038a Lg Digital Control Module subs to 6871qch038c. But that's just a first something I would check in this unit. Replace also capacitor C19, 630V big blue square cap very common failure for no video. You might want to shop this one thee are a host of problems with this unit that would certainly get some needed attention if a qualified tech were testing it and looked up the bulletins.
Good Luck!

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
