Hi, The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. Few examples are given below; some of the issues may be resolved without the need for service. 1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set. 3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue. 4 blinks: - This indicates that there may be a back light or lamp power problem. 6 blinks: - This indicates that there is some kind of audio problem with your set. 7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced. 8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset: Try the following steps to check if the issue can be resolved. Turn off the television. Unplug the television power cord from the electrical outlet. Let the television remain without power for 60 seconds. Plug the power cord back into the electrical outlet. If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television. If the issue continues to occur, service may be required. Thanks for using Fixya.
To answer your question;
In sony tv`s the seven blinks(sony error codes)usually means a high voltage safety shutdown( h.voltage has exceeded 33k volts) and is usually caused by the power supply regulation and/or the horizontal deflection circuit.
Which means that some repair will have to be done before it turns on again.
Hope this help. Happy Holidays
Follow the instructions from the image provide and see if that works, if it does not work; you have a hardware failure in your TV. The hardware failure could be the HOT or flyback transformer.
Let me know if you need further assistance.
The Sony error codes go up to 7, so when the standby light flashes 11 times it usually means that one of the clock or data lines deep inside the set is shorted to ground. This is not fixable from the front or through the remote, so the set should be serviced by a qualified tech familiar with Sony sets.
