Four blinking red lights.

Hi, My sony bravia model KDL 40S2010 did not start up this morning. The standby light flashes four times and then pauses for a few seconds and then flashes again. Grateful for any help you can offer to help me. Thank you . I have the same problem. I replaced the inverter board but the problem remains. What else could cause this?

The error code is triggered by the inverter fuses, which blow when the inverter fails

14 blinks to Sony Brand LCDs indicates a 'Backend error'. It means that, the main board to this TV should be checked for fault. In most cases the main board might need replacement, and a software update too. If you wish to know more details about this blinking code, check this link. It has details of blinking codes to several brands of TVs including Sony. Actually the work is a skilled one, need experience.

Goes from on to Standby by its self because of protection mode that activates for some internal problem. Do you see standby light blinking on tv front? What is model number of your tv? How many times standby light blinking after 3 seconds long pause? Let me know to find out possible cause of problem.
