I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction. Lets do a simple test to check the functionality.

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
