Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

SOURCE: No picture or sound. Red light

Just a correction, it is not necessary that 4 times red light blinking always shows inverter board problem.
It depends on chassis/ model number of Sony bravia tv to what is error code of 4 blinks as it would be mentioned service manual.
I'm Sony tech and can help you, let me know model number written at back of tv to provide you exact info about 4 times red light blinking.
Thanks.

Dont think that it is a case of resettting but a possible failure in the main board.The power supply works but is in the protect mode and so it switches offf. the faultt can vary with a faulty capacitorr to a shorted drvier.
It is important to open and look for the voltage short in the circuit by using a good multimeter and opening out the shorted circuit to confirm. Use a continuity test to check for short in large value capacitor/ display drivers/transformers.
If you notice bad solder joints do a touch up solderring job with care not to tamper or bridge circuits.
Credit if this helps.

G'day Lee, sounds like you may have a 'dry joint' meaning the solder has come adrift, to open the back up will need special tools to fix it. Hope you can get it fixed. Cheers Greg.

Most likely it's a capacitor fault.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the unit and be able to use a soldering iron. If this isn't you then take it to a repair shop.

Sony is, by and large, a reliable brand. The problem is that Sony like most other manufacturers has to buy capacitors from 3rd party suppliers who bid on price. Unfortunately the cost cutting has affected parts quality.
