Blinking red light 5 times Sony Bravia 55" tv

The Sony Bravia KDL55NX810 tv powers up for approximately 5 to 8 seconds then automatically turns off, then red light blinks 5 times. I replaced the main board but that didn't fix it Where can I get a diagram of the boards and their names?

How can I fix it ? Or do I need to call a tv repairman?

@bo1 the 5 blink error code can have quite a few different causes. Ranging from the T-con board to the panel and few things in between. If you have the original TV remote than try to see if this will work on your set:

1. In standby mode, press the following buttons on the Sony remote:

DISPLAY....5....VOL(-)....TV POWER

2. On the left side are the blink codes. On the right hand side is the error count.

3. Under 005, you'll see three listings... TCON, HFR, and P-ID (panel).

4. Let us know what errors your set shows.

If that does not work on your set, then you will have to remove the back of your TV and check the boards. Try to rule out/in the T-con board as faulty. Disconnect the LVDS cable to the T-CON board, the cable between the Main board and the T-CON board, and see if the error code will change. Let us know what the result is.

i change also lvds zick but it did not start.

on panel showing 12vdc.


Netram Rojh did you follow the above flowchart for your model?


I am facing the same problem. The red light blinks 5 time and one. Technician has said that its circuit panel needs to be changed. He is charging₹4500/-. He also said he will take the tv to the workshop and it will take 4days to get it done. Pls suggest whether this person is saying right or he is not a reliable person. Pls answer my query urgently


vaishalijthakkar if it is the asme make and model TV try the troubleshooting first. Replacing the panel is always the very last thing because of cost and availability. Yes he could be right with the price. 4 days maybe a bit long but he is possibly doing other jobs at the same time as well.


Hai is it major problem or minor problem of blinking red light in kdl w800d Sony briva tv because just one year I had purchased I think Sony brand will not come mechanic problem but totally I disappointed please give advice
