Question about Televison & Video
The TV clicks and shut down because an internal fault is detected. This cause the TV shutting down and going in protect mode.
To start ensure that you go through the basic troubleshooting illustrated here: Why my TV does not start up?
Basic troubleshooting consists in disconnecting the power cord for fifteen or twenty minutes.That will hardly fix the problem, but must be done.
If that does not work, 7 blinks means that there is an horizontal deflection problem.
This is usually caused by faulty convergence ICs. Both the convergence ICs located on the D board must be replaced. The Pico fuses located near to the ICs must also be replaced.
Job is done de soldering old components and soldering new ones on board. Better using soldering compound to do the job.
The ICs to replace are marked IC8002 and IC650. They are both MCZ3001D (power amps). The ICs must be de-soldered using a proper iron. The cost of each IC is about $15, the labor is about $100/$120.
