Blink codes are the auto diagnostic system in some TV Brands. Blink
code can tell us the faulty section of the TV by the number of time
blinking standby led light. When a system diagnose the fault in any
section of the tv it turn the the tv on into standby/protection mode and
displays the blinking.Sony Blinking Code:
Following blinking codes behaviors may be different according to different models:
No Blink: Its mean unit is dead. Check VDR and Fuse is the Power Supply
Continuous Blinking: Problem in Jungle IC. Communication is broken
One Blink: Not used for mostly models
Two Time Blinking: 2 Blinks Error

Panasonic Blinking Code:
One Time Blinking: 1 Blink Error
One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in
the field. Therefore a replacement is required.
Three Time Blinking: 3 Blinks Error
Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP
board is repairable. Therefore the use of an ohmmeter and peak-hold voltmeter is required to determine the cause of the shutdown. An over voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Four or Six Time Blinking: 4 Blinks, 6 Blinks Error
The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board.
The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Five, Seven, or Eight Time Blinking: 5 Blinks, 7 Blinks, 8 Blinks Error
The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V
sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Nine Time Blinking: 9 Blinks Error
Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A
board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Time Blinking: 10 Blinks Error
Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of
the power LED requires the replacement of the A board.
Panasonic Plasma Blinking Code:
All Panasonic Plasma TVs feature a protection circuit that will force the TV to shut down in case of a problem. The malfunctioning part can be identified by the numbers of blinks of the power light.
