I can unplugged from main my TV and waiting some time and then try to measure something,could be the problem some component belong to this circuit like resistors,capacitors?or is the transformer it self?

This will almost certainly be a problem with the Line output transformer, sometimes known as the flyback transformer. It will need to be repaired by a qualified technician I'm affraid as there are dangerous voltages on this part even with the set unplugged from the mains.
Try this: unplug the set and wait about 10 or 20 minutes. This is to make sure that the main power supply filter caps completely discharge. Look on the power supply board, close to where the AC cord attaches to the board. Look for a white resistor labeled "0.1 OHM" (the symbol for OHM, like an upside-down U) and measure it with your ohm meter. If it is open then your switching transistors in the main power supply are most certainly shorted. Older sets had 2 separate transistors on little heat sinks labeled "C4834", then they switched to 2 transistors in one package labeled "MX0841" or "MX0842", and then some sets went to two separate MOSFET transistors. Measure those parts and post your results and we will guide you from there.
Sorry,there are no resetting button,unplugging,waiting for a period of times,ruplugging tv it back that is ur reset back to the factory setting.Tv have the same problems,not working.The power supply board have problems,it dying.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Unfortunately the vertical colored lines usually indicates the lcd panel is faulty. Replacing that part is usually more expensive than just replacing the TV. If you want to try a fix there is a multi wired cable that plugs into the panel. there is a slim chance that reseatting cable on both ends could help.
Phillip you have a problem in the main power supply or in the High voltage shutdown circuit. Now the longer you wait to have this fixed the more its gonna cost ya Unless your a tech then get a schematic and measure the voltage on the hv shutdown pin on the video junglke ic when the set shuts down If the voltage at the time of the shutdown sodent spike up then you know your problem is in the power supply. Good luck
