Display Of Standby LED Count
Standby LED Count Display It is very important for the user or technician to understand how to solve the red light blinking error. Consider the red light blinking error: For example, if your TV has a 2-blink red light error, the red light of your TV will blink twice, and then after a three-second interval, it will blink twice. I will also put its chart in the form of a picture below so that this formula can be easily understood. It can be very useful for users to know this. The user can decide for himself what the fault in my TV is.

My Experience with Sony KDL-50W800 Blinking Error
2 times blinking (Main Power Error)
2 times blinking fix In this model, the LD Plus power supply board is used separately. The function of this board is to provide supply to the main board and to provide supply to the backlight. To fix the two-time red light blinking error, you should check 12V at the output of this board and check the 19V supply at its main jack number CN9000 because the reference required for two blinks comes from the main 19V supply.
3 times blinking (DC Alert & Communication Error)Â
To fix this error, you first have to check the voltage of the 5V voltage regulator. A slight fluctuation in this voltage can cause errors. Number two, this error is also related to audio. Check the 19V supply on the audio amplifier IC. Check the communication of the IC to the source connection with the system IC.
5 times blinking (Panel Communication Error (12.5V NG)
To fix the 5-time blinking error, you will have to check the VCC voltage of the panel, 12V. If it is OK, then check the LVDS cable, especially the clock data points, to ensure that their connectivity is correct from the main board to the T-con board. If all this is correct, then your T-con board is faulty.
6 times blinking (Backlight Error)
A 6-time blinking error is caused by a backlight fault. Usually, edge backlight is used in this model, which I think gets damaged quickly. Apart from that, this fault can also occur in the LED board. Check the boost-up circuit in the LED board. If the voltage is boosted and then disappears, then there is a high chance that the backlight is faulty.
7 time Red light blink errorÂ
7 times blinking An over-temperature error occurs. If for some reason the main IC overheats, this protection is activated, or if the clock data of the temperature sensor IC does not communicate with the system IC properly, this error occurs.
