My Sony standby blinks 7 times. Early on the unit wouldn't turn on until I pressed the power twice. now the unit doesn'tcome on at all.it just makes a couple of clicks and then the standby light blinks. TV repair guy said he has seen it before and that it is an intermittent short in the tube -- oh well. I guess I have an excuse to get a new 40" LCD HSTV ;-)

Sony kv-40xbr800 stand by light flashing no picture


How many times do this standby light flashes? These flashes are fault indication, called blinking codes. From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the number of flashes. If you wish to get more detail about these blinking codes to Sony TVs, check the site linked here. http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

KV-36XBR400 won't turn on, "standby/stero" light


You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

My standby light blinks 7 times ?


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.

Sony kv-30xbr910 my tv won't turn on and the standby fashes 7 times


Good day.
Your unit has issues with the high voltage section. Particularly the vertical and horizontal sections. Blinking lights indicates that your flyback is not osscilating to distribute the supply to the sections. Please have it checked by a repaiman.
