I got this screen off DX a while ago and when I got it, the screen was just all white. For ~8 months, its been just sitting and collecting dust. I just bought a broken PSP and decided to try the screen again and the screen isn't as white anymore. I could see a little blue now and read the words. Is there a way to fix this screen?
Sometimes when I turn it on, the colors look inverted.

looks like you got ripped off. Y didnt you return it when you first found out it was bad? Well I don't know how to fix it but I'd say to disassemble the screen and see if you can see anything wrong with it.

I sent in request to get a RMA but they never responded... I already tried taking apart the LCD.

try taking off the backlight and then put a flash light up to it so you can see if it might just be a faulty backlight

That is what controls the color of the screen? So i have to desolder it and solder it to my screen?

Hey man I can help you I got like 3 of the entire thing riped from the glass somewhere are you in the U.S I have one in my hand now from a cracked LCD that has fine color but its cracked its still hooked up too so if you are interested 5 bucks and ill ship you 2 of the whole FPC or whatever it is I never had a screen do this on me so I know the other ones is fine too but ill send both in case you have trouble removing one

I already have 3 cracked LCDs sitting on my desk right now.. so I don't need more.

How did you know you needed to replace that chip?

I'll try to swap it tomorrow, I don't feel like desoldering and soldering right now.

Sanctus · « **Reply #14 on:** September 06, 2008, 09:37:44 PM »

Can't you just replace that hole ribbon thing rather than having to desolder and solder?

folklord36 · « **Reply #15 on:** September 06, 2008, 09:44:39 PM »

the entire ribion connects to the glass with about 1000 solder points thiner than any thuman could solder all of them back on

pfft, well if your a ninja that's easy.

what exactly does that ic do? Also isn't it a little hard to solder to a thin piece of plastic that wants to curl up and melt?

ProperBritish · « **Reply #18 on:** September 07, 2008, 10:31:39 AM »

not if you're soldering onto the metal contacts... just dont be clumsy and touch the plastic.

I was just comparing the screens it turns out the screen from DX is missing 4 resistors!!

hmm that dose not nessicairly mean they are missing lots of PCB have missing components it seems but it is just revise versions of the same thing and sometimes multiple resistors are used in older ones or originals and later they are consolidated to one but they tend to use the same PCB or FPC or whatever it is in this case. You should still try and swap the IC If it worked for blizzard should work for you too.

Tri-edge · « **Reply #21 on:** September 07, 2008, 06:36:23 PM »

and if it still doesn't work you can also add the resistors

really? ok i have to know, how can you tell the difference???

If you look at the second picture that psp339 posted, you can see the labels and numbers next to each component, C = capacitor, R = resistor, D = diode.

psppunk · « **Reply #24 on:** September 12, 2008, 12:14:04 PM »

so, other than board markings, theres no way to tell them apart?

folklord36 · « **Reply #25 on:** September 12, 2008, 08:25:41 PM »

smart tweezers or a multimeter that can read caps most can read resistors but ya they are normally marked C** for caps R** for resistors I didn't notice the markings just made an assumption.
