Not having had a 3/600 generation reader, I can't speak from experience, but if they had the same eink technology screen as the 3/650 and T1, this shouldn't happen, and you may have a hardware problem.....

However,  I have a vague memory of someone in Waterstones , when I first started thinking about getting a reader, a salesperson saying, about the 3/650, that they "now have a screen enabling you to read easily in sunlight."

Which perhaps indicates they had improved technology? Or they may simply have been comparing to other readers which didn't have it at that time.

Have you had it long ?

Anyway, someone out there must have first-hand experience - if you have no luck, PM me.

I had this same problem with my 600 the first time I went on holiday. At the time the reader was about 8/9 months old so took it back to WHSmith and got a full refund.

Then bought the 650 which doens't have this problem.

Unfortunately the 600 is a terrible reader and I'm very glad I got rid of it. The 650 is, for me, perfect.

Tried to PM you, but your avatar  name not recognised...

I wouldn't hold your breath.  I discovered this problem almost as soon as I bought my PRS600 because I use my eReader on the boat and so reading in 'direct sunlight' was why I bought the Sony in the first place.  I spoke to somebody in Sony about it, and was informed that direct sunlight does not  actually mean direct sunlight and that text disappearing is perfectly normal.  What a load of tosh, but of course no joy on any refund or replacement as my eReader was a present, bought at my request.

Well that is good to know - I might just invest in upgrading to a T2 because it sounds like it might be worth it.  Ufortunately it does not look like it is available in the UK yet so I shall have to be patient - not my best suit
