Swimming PSP's <Need Help>

[NeOCzx]

Yesterday...
my fren come and giv me his PSP...
the PSP went swimming once 2 years ago...
so i try to get the PSP working again...
after open the psp can clean it up....
i manage to get the PSP half working...
wif no backlight... but luckily the LCD still ok...
so i plan to make own backlight wif cellphone keypad LED...
but now my problem is...
the PSP wont detect my slim psp battery..
when me turn on... nothing happened....
when me plug the adepter on... the PSP boot up like always..
but the power LED keep blinking..
orange and green...
Does anyone got same situation as me??
or got anyone got same experience wif me<swimming PSP's)
or we can use the slim PSP`s for phat ones?
thats giv me hard time..since me cannot flash The CFW...
its firmware is oficial 2.00

i just have to your pretty lucky you might as well have won the lottery that the kind of luck you must of had

sounds like an extreme short i can't really tell what the problem is aside from the fact that it went swimming

[NeOCzx]

maybe... no other way to detect where it shorts?
but the button,memory card, and speaker works well...
question plz...<me a nubbies.... sorry >
can we use slim PSP battery for Phat...?
or maybe got sumthing like power fuse that already pawned by water~?
it was already 2 years ago...me think all the water already went dry... and my dumb fren...
just giv me the things now... after he sees me modding psp...
can hard wire from AC/DC adapter to battery can solve this...? but pandora battery wont work? isnt it?
or thats got another way to put CFW without pandora battery?

first worry about the psp not the custom firmware

u tried bridging the backlight fuse? so the backlight will turn on

and i dont know if slim battarys work on a phat psp

loi yea same here i don't really know where to start with the plethora of problems you have

[NeOCzx]

tried bridging many times.... no effect..
until me pawned the fuse itself ><
me need to hold wif hand in order to make the backlight work...
now even the existence of the backlight is still unknown... <me lost it... lol>
so me plan to make own backight wif keypad LED's
any sugestion?
should i use 22v? or 5v?
or how much LED? 6 maybe?
and what value of mA of the standard PSP backlight LCD?
me maybe end up to connect the LED parallely.. about 20 ohm resistor of each LED.. wif 5V...

i saw somewhere you can just use a white led as backlight so that could help you

im pretty sure i read somewhere the u cant use slim battery with a phat one but dont quote me

Dude chill out!
Don't do anything else, do only what I'll tell you.
Leave the backlight fuse bridged,
don't add any leds for backlight!
That is stupid,the psp screen is damn wide and you can't light the
whole screen and if you do then you'll need an enormous amount of led,
power and it's gonna be dim.
The only problem that psp has is backlight,so don't touch other stuff!!
The slim battery isn't compatible with fat as I know.
Now the only thing you have to do is completelly disassemble the psp
and take only the motherboard,then take cooking soda(powder form),
mix it with water and with a soft toothbrush rub softly the components of
the motherboard and rub the backlight connector too from the inside(don't rub
the screen connector as it is ok as you said).Then dry your motherboard with a napkin
or with an air blower(not hot air from a hair dryer) and once it's dry reassemble it.
Then backlight will work. Water is salty(hard water) and that's bad for electronics,
you're lucky it works and when it dries salt remains on your components.
Probably the backlight connector is salty and doesn't connect well.
If you clean it the way I told you it'll work.

yea, i might not know much of modding but i know alot about firmware and abttery related things, and no the slim battery will not work with phat, the slim battery has 1200mAH and original phat battery has 1800mAH they both have same voltage(3.6V) so the slim battery might not provide enough power to the phat PSP
