psp turning on with sound, but no picture
« on: September 21, 2010, 03:33:45 PM »
Hi all, I'm new to forums so sorry if this has been posted before.

So yesterday I was switching psp cases and once I finished installing all the psp parts inside the new case and turned it on, there was sound but no picture.

Any solutions? Thank you so much!

Check and Double check the back light and the LCD screen cable, its probably loose and you need to ensure the connection to the motherboard. I doubt you have blown a fuse... if anyone mentions it.

The backlight is the screen itself, right?

I checked the LCD screen cable and it's secure. I've also tried using new LCD screens to see if they work, but no luck. Thanks anyways :/

I'd also like to mention that I can see a bit of the psp xmb under a really bright light titled at an angle.

Is the backlight the skinny cable? If so, that is definitely plugged in.

 your black light fuse on your psp mother board is blown....from what you have described. just bridge the fuse with some solder and it will be good as new :tup:

Cool, thanks! :)
Is there a tutorial on how to do this and where is the backlight fuse?

Thank you! What do you mean by 'bridging' the connection? Sorry, I'm a newb at these things. :S

solder a wire connecting the 2 ends of the fuse.... or put a glob of solder over the fuse so the sides are connected

Which method is easier? Also, just solder the backlight fuse, not the LB sound fuse?
