STR F6654 is not workimg ,power led is bliking what is the cause?


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.
If STR does not work, how do you get the power light ON at its front panel?

Str f6654 diagram


Check all the solder terminals to this Regulator IC, for any loose soldering. It will be best to resolder all the solder terminals to this IC, by applying a little more solder to each solder terminals, without making any solder bridge short in between adjacent solder terminals. Take extreme care when soldering procedure, as there will be dangerous voltages will be present, even after switch off the set. If you wish to get the schematic diagram for STR F6654, get it from the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by its left side bar, or view it in Timeslide option.
