Usually it is a power supply problem, so check voltages, 5V circuit is usually the culprit caused by leaking capacitor, so you have to look closely at tops of the large capacitors on power supply board and if top is swollen, that is problem, very typical in all flat panel TV's, cheap fix for about $6.00 if you have solder gun.

Good luck. FREE-PPV

If you're not an electronics expert, your best bet is to get the number off the main board and look online for a replacement. There are a few places (Shopjimmy is one) that have boards pulled from broken TVs. I did that a few years ago - spent $50 and a couple hours and got my TV back working.

But before you shell out even the 50 or hundred bucks, try a trick I learned over the weekend that fixed a TV that was not receiving any signal from the HDMI inputs. Some problems, especially those resulting from power surges, can be fixed by baking the circuit board. I know it sounds strange, but removing the main circuit board and putting it in the oven (NOT THE MICROWAVE) at 385 degrees F for 10 minutes may do the trick. It remelts the solder on the board just enough to restore connections than have been broken by a power surge. If you're down to replacing the main board otherwise, you have nothing to lose. Google "baking a circuit board" for more info and specifics.

Anti theft light won't go out


There are 2 things to try:
1) Use your key to manually unlock the driver's side door - sometimes this alone is enough to reset your security system.
2) Put your key in the ignition and turn to ON position (do not try to start the car, just turn to ON)- after 30 seconds, attempt to start the car and see if the security light goes out.

2003 impala everything works won't start won'crank


If you try to start the vehicle and there is a click when you turn the key, but does not start, you may have a solenoid problem. This is usually about 3 inches long and 1.5 inches in diameter and attaches to your starter. Try giving it a sharp tap with a hammer as this is often enough to loosen contact points inside.
