Question about Flat Panel Televisions
I've replaced both MCZ3001D IC's on the D Board and it worked for a whole day. Next morning, back to 6 blinks. Can solder and have DVM. Any components more likely going bad with 6 blinks? Thanks
For 6 blinks Pls check following area.
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.
And NOTE: 6 blinks also can be Low B+ protection.
Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.I think this will help you to solve the issue.
Dont forgat to Rate!!
