SELF DIAGNOSING SERVICE MODE AND POWER SUPPLY CIRCUIT

I checked on the schematic, there is a self diagnostic mode for the tv accessed with the remote control. If the TV does not turn on I would highly recommend finding a local reputable service facility as this might be completely a fault inside the TV. https://www.encompassparts.com/shop/model_research_docs/?file=/SON/sm/KDL46V4100.pdf

Please check page 12 for self diagnostic procedure.

Hi Mizanur,

First of all, thank you for posting your question here at Fixya.

Your TV has a built in self diagnostic software that can help us diagnose accurately where the fault came from once the unit gone to malfunction. To activate it, press the following buttons on the remote control within a second on each other in standby mode( red LED is on), "Display", "5", "Volume (+)", "Power". Initial screen will be displays as follows :




To display the self diagnostic list, press on the remote control.

The screen will display the list of error log as follows :




Numerical value "0" means that there's no error detected, "1" means that an error was detected.

Please let me know what error code(s) with numerical value "1" to continue our diagnosis.

Kind Regards,

Hi Gerard,
3 flashes of the led light on most KDL series is a power supply malfunction. To confirm the error code, lets access the self diagnostic screen by following the steps below.

Unplug the unit from the outlet for 30 minutes and then plug it back in and check if the symptoms remain the same. Wait until the led light stops from flashing and then press in rapid sequence the "Display", "Channel 5", "Volume (-)", "Power" button key on the remote control. Self diagnostic screen will be display. Let me know the result.
