So before reinstalling my ancient 7" Microvision LCD, I decided to make sure it still works, so naturally I connect the turn on, power, and ground wires to a good ole 9V battery...aaaaaaand...nothing. Well, sort of. The screen goes dull white for a split second, then off, then one again for a split second, lather, rinse, repeat.

So am I doing something wrong with this insanley basic test, or is it shot?

PS - If it's shot and anyone has one lying around, I need to buy it.

 

You may want to try a 12v source

9v is probably at the lower limit or right below its operating voltage.

 

yea id say use a 12V source, ive had similar problems with computers monitors

 

would have thought you'd guess this, Metal. typo?

 

lol, no typo. IIRC, it does fully power and illuminate blue when powered from a 9V source, but I mihgt be wrong on that. I was testing it late at night and hoping this would provide ample powah, but we shall soon see if such is the case, or if I need to get a Lilliput TFT...

 

touch screen ftw anyways. what are your plans? or are they top secret

 

Nothing top secret. I am about 90% done the final interior overhaul and needed to test zee screen before putting it in the center console.

BTW: 9V works, turns out the battery just did not have enough juice to power the LCD, we're GTG
