Likely power supply failure. Sometimes affecting the series of sets.

Remove the back panel (unplugged, of course), locate the power supply which will be a separate block of components with larger, coarser parts.

The parts most likely to fail (electrolytic capacitors) may be exposed enough to examine them.
Look for cylindrical parts, usually 90 degrees from the board plane, with exposed aluminum that is scored, mostly in a "Y" pattern.

Look for any whose tops are bulging or indeed split open along the score lines.
This is about the only visible indication of failure, otherwise a special (LCR) meter will be needed for testing.

If you find such parts, you might try emailing Sony to see if they have an exchange program on the supply; these are not tough to remove and replace.
If not, try to find a local tech who will check the possible failed parts and replace them.

If you go this route, tell them to add 0.1 to 0.47 microfarad (25-50VDC OK) ceramic caps (under the board) parallel to the replaced parts
This will prevent renewed failure of the capacitors by bypassing the chemical caps for the high frequencies which causes them to fail.

SOURCE: No sound no picture, the stand by light blinks four times

If you have the above model, then the four blinks indicate a backlight failure. The back light inverter board might be defective or the voltage from the power supply (+24v) is low or missing.
Let me know if you require further assistance.

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).

The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

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.

It does sound like a power supply problem but that can be misleading because a problem somewhere else in the TV can be "holding down" the power supply. This can usually be determined by using some isolation techniques.
