I have same problem in my a/ c does anybody knows how too repair. It

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty.

Look thru the set up menu and see if there is an ambient light setting that adjusts the brightness of the TV based on the light level in the room. If there is then turn it off.

Do a hard reset to this TV, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Take a flash light and shine it on the tv screen at an angle . if you see any picture then the problem is with the backlight or the power supply for the back light. if you see nothing then the problem is somewhere else. it can be the T-con board or the lcd panel itself.

Base on my experience. It's time for new one. Fix it or replace parts will end up more then new one. Good luck Mai

First, test fuse if there is one. Second check high voltage near 390 to 400 DC volts at the capacitor. Hopefully, there is only one capacitor.. The high voltage circuit is near where the AC 120 volts plug enters the TV. So, without high voltage, TVs are shutdown. Today's TVs are like computers, sensors on the circuit boards, feed back to a "CPU".

Backlight check

There should be a label on the inside of the cabinet saying what the voltages to the VS and VA should be along with any other voltages that are adjustable, have you set the various voltages to the correct specs

Your issue is in the LED lamps or power supply, test the voltage at the connector that comes out of the power board and see if you have voltage there of 100 plus volts DC, if you don't unhook the connector and see if you have around 150, if you do then you have at least one lamp that is bad and needs replacing, if there isn't any voltage there its the power board

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

Press the settings or menu button on your remote. There should be an option for aspect ratio. Set it to widescreen or 16:9

Good version
