About LinkBacksThanx for that info.....I'm trying with both composite or VGA, but getting no luck at all.
Thanx for that info.....I'm trying with both composite or VGA, but getting no luck at all.
If its comleatly dead, ill have it.. £5 inc postage sound fair? Some of its parts will be usefull (ccfl backlight etc...)
I'll see how I get on with some different connectors for the composite try, and then with some resistors for the RGB try.
Proplus what lead you using to connect it from your grapgics card to the screen?
Scott
OK...
PC TV-out socket > the supplied connector from the GFX card which splits into S-vid or composite > composite cable > composite to mini jack converter > LCD
I'm not taking the mick mate but has ther mini jack u have got 3 stripes round it, as I started by usiing just a stereo minijacj (2stripes) and it didn't work.

Silent have you got a voltage reg circuit working?
I'll be constructing one this week and some maplin part numbers would be handy!

kez - not really
Ill be trying a LM317T later when I can be arsed.
This is basic circuit, google for a better one.. http://www.mitedu.freeserve.co.uk/Ci...ower/lm317.htm
You need to set the output with a multimeter. The output might vary under load (although I assume it wont as its designed to regulate...?)
They are cheap and dont need many parts, but a normal fixed output regulator would have been nicer (as its the only needed part).
Pls remind me is 1nF bigger or smaller than 1uF?

errr.....its only got one stripe!! I'll keep a lookout for a 3 stripe one.Originally Posted by skotbites
another way is using a 9.1v zerner diode, maplin number QF52G. 9.1 is slightly too high. 0.7v will be dropped from the B-E junction, giving 8.4v, then using another diode (not a zerner this time, 1N4001 should do) dropping it by another 0.7-1.1v to 7.3-7.7v, which is perfect..
also see here on how to use the lm7805 http://www.mitedu.freeserve.co.uk/Ci.../Power/vvr.htm

uF - micro farrad, nF nano farrad, I think nF is smaller IIRC.
edit: Yeah it is - think CPU cores, 0.9u (microns) is the same as a 90nanometre core.
Cheers Silent I'll take a look.

makes more sense now... heres another lm317 schematic looks almost same.
edit - HERE
Any one took the lid of the psu cube for it? im finding it almost impossible to get off... anyway I think the circuit inside might be useable to regulate from around 12 as thats probably the output voltage of the transofrmer inside.

Here's another you say? Yet where?
PHP Code:$s = new signature();
$s->sarcasm()->intellect()->font('Courier New')->display();
just opened the psu cube WITH A DREMMEL!!! bloody psu case couldnt they make them easyer to open????????????????????????
It has a large capacitor + small ones, a transformer 4 diodes (for rectifing probably), and two TO-220 style chips, probably regulators of some kind. Unfortunatly all the specs are on the sides hidden from my view.
Proplus, I had real trouble finding one and in the end had to pinch it from my dads camcorder!!!
Scott
the transformer has written on it:
MP-130B 1801
SMT-25H-NB238
DC6M12 0239( 01 )
Im not sure what this meansalthough I think it might be 240v in 25v out, which sounds right.
The psu was of the switching type, meaning none of the to-220 things would be at all usefull, and niether would msot of the other parts...
I didnt intend to ever use this psu cube again, so have now desoldered usefull parts, capacitors diodes etc...
