Brand new 4603-9101 LCD Annunciator displays System Normal, however trouble light is lit. Main FACP displays system normal. Question is why the trouble light lit on Annunciator and what is wrong.

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK

SOURCE: System Low Battery

Response 1 is correct. If you plugged the transformer into an outlet before connecting the battery the system wont see the battery and give you that error. Should be a simple fix however. Unplug the battery and then the transformer, then reverse the process. Plug in the battery and your Simon should power up, then plug in the transformer. If this doesn't help then you should replace the battery. Did you buy the system from a dealer and have it professionally installed or did you do-it-yourself? If it was professionally installed have your technician come back out to diagnose/replace the battery if needed. Good Luck.

I just read in another forum that the LCD display appearing black (but backlit) could be due to the ribbon connectors being loose behind the screen.
You would have to open the unit to check...
However, this would most likely void your warranty if your unit is still under one.

Hope this works...

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

SOURCE: Display powers of with power up of AVC

This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.
