Iphone4S screen stays blue, won't shut off. nothing works

ok, does the entire TV shut off or just the screen?

hardware issue i think

I have minor shutdown problem with mail, won't close or shut down. My ans top left APPLE drop down, force closure, turn of each programme listed. For me works a treat.

the fan on the CPU working? Try a different power supply the one you have might be faulty

Try changing the input device to something you are sure, works such as a DVD player. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

is everything working properly? I have an iPhone4 reply back please what happened to yo iPhone

Press and hold the power button and the menu button.Wait until the apple logo appears.

Hello!
"blue screen" means: picture is all blue, but there is a signal coming through? Do you see channel logo? Menu? If so, blue CRT or CRT board is at fault. Depends on the age of the set. If set is fairly new, then try to bang on the neck of blue tube with rubber screwdriver hands. Very gentle! While set is working. If you see the retrace lines and TV shuts down then, CRT is at fault. If not, try to play with blue "screen" control of "focus block". Black plastic module with bunch of thick wires attachad to that. Has 3 "focus" and 3 "screen" controls. For each of the tubes. In many cases you'll be able to adjust "blue" down to normal. Usually, those controls are smeared with white paint and hard to turn by hand. Loosen those with little pliers, then adjust manually or via small "phillips" screwdriver. If nothing helps: CRT board is at fault and must be replaced or repaired. In this case you won't see any characters on blue CRT, just solid "blue".
good luck,
Alex.

Yes. It's broken.

Hi, maybe you can take a try of this rescue program called BootSuite. I came across similar blue screen situaiton on my HP laptop (win 7) and it helped me get rid of it and rescued my data back. It is an awesome toolkit that includes a boot CD and several other data rescue tools that help get your PC going even if Windows won't start or computer won't boot up at all. Good luck.
