Yes, Gamey did you say the inverter circuit is simple? Well you'd better put it up quick or we'll hunt you down

Hmmm... wonder if this is more efficient

1W @ 3V, 3W @ 5V and 4W @ 6V.

that good and low?

Those are not happy numbers! 600mA AT 5V?
Nevermind! The LEDs are back in commission.

actually, they most likely are

....I can't seem to find a place with the actual inverter (or any data sheets, for that matter). all it says on there is:

"1001
D992

sumida"

I'm telling you, though, this inverter works great (only uses 100mA of power at 7.5V!) but I just can't find any data regarding the actual inverter

oh, btw, I measured 200V at the output with the ccfl tube connected....and 250V without any load. perhaps someone could find an inverter with similar specs..I've looked, but I can't find any

if it's any consolation, check old GC screens for inverter circuits....with any luck, you should be able to find one on there and it'll hopefully work

I got mine from one of these

I checked the Sumida website and couldn't find any that output 200V, I'd check the CCFL of the psone lcd to find out if it has a datasheet so you can find it's exact requirements.

Rev 3 of the PSone's LCD module: http://www.itradekorea.net/data/sm5pane ... 030904.pdf

The CCFL runs at 690V.

edit: Do you have a part number for the LCD and/or backlight in the gamecube screen?

The 289-1134-ND from digikey should work fine, although I'm not sure if it'd cut down on the draw at all. I assume gamelver's cut down on the draw because it's under powering the ccfl.

Post by **Gamelver** » Sat Nov 05, 2005 4:04 pm

the 289-1134-ND wouldn't cut on draw much, if at all, I don't think....anyway, I'm gonna go and find the rest of the lcd board and see what I can find out...

oh, and I'm sure I read 200V at the output....if it is underpowering the thing, then why would it consume LESS mA? wouldn't it need MORE

?...hmm.....

Edit: ok, here's the part number around the backlight portion of the pcb...

DPWBX1039CPZZ Sharp

Edit 2: actually, the 289-1134-ND only uses around 200-400 mA of power...so you'd save a little power, but not enough to justify it being used as a replacement for the LEDs
