Hi,
Your problem is the T-con board. This is gone bad/faulty. I would advice you to replace it with new T-con board and your unit will back to normal again. You may look for the replacement online. Try ebay.com or shopjimmy.com.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Look on the side/back of the set for the control buttons. Try them. If they work, then you can do a quick check of the remote by;
Get a digital camera (turn on) and point the remote at the lenses.
If you see a flash on the lcd display, the remote is giving a signal and the problem is probably in the remote sensor on the set.
If you do not see a flash the remote may need new batteries.
No camera? check the batteries anyway.
