Sony KDF-42WE655 Won't power on. Red Power/Standby light blinks 5 times

I have a Sony KDF-42WE655 and recently replaced the lamp. Now, a few months later, the TV won't power on. After the green Power/Standby light blinks for about 30 seconds, the Red light starts blinking...5 blinks at a time. I believe from many forums that this is a Ballast issue. Is that true? And if so, it seems a new ballast is about $150+. Can I replace it myself? Or do I need an expert to do it? The TV is 10 or 11 years old and if this is a $300+ fix, I may just get a new TV. Thank you to anyone who can help.

These 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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

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.

My Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?


Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

If lamp light is on at tv front then replace lamp as existing lamp sounds dead/ broken.
Lamp replacement procedure would be written in user manual of tv.
And if lamp light is not on but standby light is blinking then let me know how many times it is blinking to find out problem cause as standby light blinking is an error code.

If you just replaced the lamp then there's something wrong in the power circuit or you have a bad lamp. If you can I would take the back cover off and look at the board where the power cord connects and lok around it for swollen capacitors. Let me know if you find anything.

Tv will shut off and red light will flash 3 times


If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.
