The picture is starting to go out - when you turn it on the screen is totally white, then about an hour later, the picture begins to appear, will go out, then returns but it takes quite a while before the the picture is normal.

i started having this problem today, on the 52pfl9432d/79 i am pissed off bigtime, lucky its still under warranty, and this is not a once off problem...so i shouold be able to get this resolved within 24 hours just got to find my reciept.....lol
i have sound no picture or menu to change settings, very disappointing..

the display screen is faulty have an expert change it for you

It does indeed sounds like the capacitors, I had this problem last year with a Medion monitor where it would turn on and off, when I spoke to Medion they did say that it would need a repair but at the time I wasn't enclined to pay the repair fees for something that may happen again!

Personally I would stick with your plan of getting a new monitor because my view on monitor hardware issues is that if it's happened once it will happen again even if you do repair it resulting in a lot of hassle!

If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.

This is a processor fgailur - Canon Support will adive the best route for this

I have Fuji FinePix 2650 Digital camera with same problem. I can almost guarantee this is not a firmware problem. I went mountain biking a few months ago and take pictures. I take out camera and turn on. I get lines then white screen. I banged on camera and fixed it. Later a few weeks ago I turn it on and white screen. i beat this thing and get bad menu selection screen for a moment then white again. It takes pictures well and talk to computer no problem but no LCD picture. I thinking it is loose connection for LCD. Send it for repair or if you seek adventure try to fix it yourself!

Spounds like the b+ feed filter capacitor off the flyback that supplys voltage to the three drive transistors on the crt board is bad.
