Sure I'll be trying. What else I can do :/. The thing that pisses me of mostly is that I was only reading book and this freeze came out... No fall, no moistured... Nothing. Just using as usual.
But there is still a hope. I found some 3rd party service workshop which specializes in Sony products. But I'm afraid that they can only replace mainboard in reader and it would cost me approx. 3/4 of new PRS.
