Right then,
6 inch Plasma plate arrived yesterday evening form hong kong so heres my experience.
Opening it up it seems like a nice solid sturdy piece of glass and the box on the back really is not as big as all the pictures lead you tro believe.
So plugged it all in and switched it on. There are three switch positions, ON/Sound/Off
The on postion gives you a continous dancing array as you would expect and reacts, somewhat to you finger touchs, nothing really impressive though.
I bought this to place in the front of a Jukebox so my interest is with the sound reactions.
Switched it to sound mode, Nada, wiggled switches, carefully sliding it to very possible postion whilst shouting at it for a reactuion,still nada,
Absolutely no response to sound at all.
OK, Looking at the back there are 4 screws in the plastic housing so i undid them to reveal small , rather, shoddily constructed circuit board. My intention was to check the solder points on the slide switch and also locate the built in Microphone.
The switch looked soldered ok, although not exactly seated level but the pins were solid.
Moving on to the tiny microphone. There are two pins that attach the Mic to the circuit board, One of these was detached from the base of the Mic, so in efect there was no mic.
Out with the trusy sldering iron and twenty mins later i have removed the Mic and using some telephone wire extended it out of the unit so that i can place it in a more appropriate and receptive place later.
One word of warning.!
THERE IS A CAPACITOR on the circuit board which is just waiting to discharge itself on you, so be careful as it zapped me good, wasn't expectng it and it made me laugh, but still, had a hefty discharge on it. Lol.
You've been warned.
The only other thing worth noting is that the HT lead that connects the glass dish to the circuitr board seems very fragile and i would expect moving it a dozen times or so would snap off and render the dish useless.
Anyway, once the unit was reassembled i switched it back onto sound mode and shouted
"YOU'RE NOT VERY WELL MADE ARE YOU" to which it flickered back in agreement.
hope this helps.
