Question about Sony Bravia KDL-46V4100 46 in. LCD HDTV

2 Answers

My TV is on standby, but not turning on

I think we may have had a power surge, and for some reason I cannot get a picture on my TV. The red light is flashing for standby, but there is nothing else. I cannot find a "reset" button anywhere. I've done everyting else like unplugging/replugging, etc...

Any advice you can give would be GREAT!
Thanks,
Sharon

Inspect the power supply module, it may be in safety shutdown mode due to short circuits in the power supply or in the inverter board, try disconnecting the backlight inverter board power connection to see if the TV will come back on, you will have sound but no pictures then you will know that the fault is in the inverter board.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

When i try to turn it on i get picture and sound for about 2 seconds and then it shuts off and the red light flashes,


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection 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. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

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.

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.

The red light on the front of the TV blinks all the time. No sound or picture. It is a Sony Model KV-21s65


The TV will cause the STANDBY light to blink or flash when the TV detects an issue.
The number of times the STANDBY light flashes corresponds to a specific issue.

If the TV is plugged into a power strip or a surge protector, please remove it from the power strip or the 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 TV.

Also try connecting the TV to different AC wall outlet and check if that helps.

If the issue persists, the TV needs to be Serviced.

The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired.

Please contact the local Authorized Service Center to get the TV serviced.
