Hi


Thanks for using FixYa. From what you have described it seems the issue is with the power board or the main board and we’ll need to check few things. When you open the unit up; take a look at the power board-the board where the power cords/plugs goes into. You might see some filter capacitors a little bulged up in the top-If this is the case-this is your defective part(you can try to replace them-but some soldering equipment is needed). If not, then probably the main board has gone bad. This is the other board-where all the inputs are going into. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please note that the TV components consists high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.



Thanks
Rylee

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.

If blinks continue without any pause, the main board is faulty.
