Hi,This is what I know.
Continuous Blinking: Not getting reply from IC301 Jungle IC, Bad "IK" video path, possible short to ground

One Blink: Not used

Two Blinks: B+ over current protect, short in power supply or HV circuit

Three Blinks: B+ over voltage protect: power supply short, check transistors, resistors etc.

Four Blinks: No Vertical Deflection, Check IC1509, Q1505

Five Blinks: AKB Circuit, Check Q705,Q732,Q761, on C board, also check Q218,Q219, Q220 on A board, IK circuit can also cause this try turning screen control up a little

Six Blinks:No Horizontal, No Raster, checkC515 C516, & Jungle IC,IC206

Seven Blinks: High Voltage Shutdown, Flyback, shutdown circuits/components

Eight Blinks: Audio Circuit, IC406, PS401, PS402

These Blink Codes are stored in the set and can be looked up to see what error codes have been stored, To pull up Diagnostic Screen push; Display, Channel, 5, Vol MINUS, then power, a screen should appear with the codes and number of times they have occured. Once the set has been repaired the ERROR CODES have to be removed by the tech, clearing is done by going into the service mode; display,channel,5,volume PLUS, power. Press 8 then Enter everything returns to the factory preset condition.

Why won't it turn on?


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 section 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 procedure, to many popular brand TVs and other devices.

What does the red blinking lights on the "standby"


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.

The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

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.

If blinks continue without any pause, the main board is faulty.
