The problem (4 blink error code) on this set is rather generic---it will point to several areas none that are specific----you may be expecting too much as this is typical----again the error code only points to general issues like change this board and then that board and may not even fix the problem.

You might actually be better having a tech or a shop look at the set, sorry if this answer is not what you wanted but it is the way this set is made.

Your owner's manual for the television will contain a troubleshooting section that will describe the blinking codes for the various lights, and what they mean.
However, in your case, it probably means the light is burned out.
The bulb on my TV tends to burn out about every 16 months (I watch TV for many hours per day, so your experience may be different). If your TV is still under warranty, I would suggest you contact the store where it was purchased, or contact the manufacturer.

A 6 blink error code on this model is letting you know that your G1 board is not putting out your +17 volt supply. You can inspect that circuit if you are experianced, or just swap out the board.

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.

For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.
