Pandora fail?

[Snowpaw]

I got my pandora battery and magic memory stick today, put them in, and tried to unbrick my PSP. The screen turned on, and the console stayed on, but it did not display anything. I tried to hit X to install the firmware and it didn't seem to be doing anything, so I shut it off. Next time I turned it on (still with the two custom things) it turned on but the screen was seriously blurry, so I installed the custom firmware and it worked, fixed the screen. However...now I turn it on and it boots up, shows the backlight on, and even plays the sounds but there is STILL NO PICTURE. What gives?

If you have a psp with Ta88-V3 matherborad or Psp Slim 3000 with Ta90-V2, ther aren't hackable.

If you was on cfw, there are only two possibilities.

1) Something wrong in megiv memory stick.
2) A main board fault.

The psp did not have cfw before I got the pandora and card. Also this is a 2000 series, and my friend checked it against a list, using the serial number and made sure it was a 2000 series that is hackable. It is possible it's a motherboard problem, but if that's the case, is my only option to send it in?
