7 BLINKS OF STANDBY LIGHT BEFORE SHUT DOWNFault: Internal Temperature Protection
- The primary symptom to note when 7 blinks of standby light occurs is, how quickly the TV shuts OFF and goes into protection mode, and display 7 blinks of standby light.
- Does the the TV immediately shut down after the poser button is pressed, or does it operate OK for a short period of time and then shut down?
- A true temperature problem where the internal temperature is excessive will take some time to detect. The temperature itself will take time to sense the temperature and communicate the information to the Main Microprocessor. If the TV immediately shuts down, the the protection sensor IC1007 has most likely failed causing this fault. If so, replace B-board.
- If it takes some time for the TV to shut down and produces 7 blinks protection indication, further steps must be taken to resolve this problem. Check the TV ventilation, room temperature and TV mounting area.
- In most cases, cleaning the TV vents, adjusting the room temperature and/or remounting the TV must solve this problem. Confirm that the TV is not mounted too close to home heating elements.
- If these does not solve the problem, check the internal components. Although this is an extremely rare occurance, check G1/G2 board, and LCD panel assembly for excessive heat.
