Psone screen Backlight

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Psone screen Backlight

Post by GamecubePerson111 » Wed Jul 14, 2010 8:42 pm

I was using my psone screen when all of a sudden the psone's backlight stopped working. I can see the picture very dimly but the backlight does not turn on. I was wondering how should I go about fixing this. Thanks

Replace the backlight with LED's or get a backlight from someone on the forum.

Are you powering the screen off batteries? They may not be powerfull enough. Usually the stock CCFL backlight shuts off if the screen does'nt get enough amperage. I think it needs around 650-700ma to run unmodded. Also check if the backlight plug is properly attached.

You have either

1) Fried the Transformer to get it from whatever voltage (Lets say, 12v) up to I think it is 10 000v to power the CFCL tube. Though, you would of herd a 'hisssssss...' sound from it if that happened.

2) Shorted out a pin somewhere? Which is unlikely as you said it is dim...


Just do the LED mod. That is is best option as the CFCL and Transformer will use a lot of power for nothing. Oh, and there quite dangerous too :D
