Your iPod touch shows a lock symbol on the top of the screen when it's in lock mode. This protects your iPod from being accidentally bumped on or off while you're focused on other things. Getting in and out of lock mode is somewhat intuitive, but can take a couple of tries the first time.

What Does Lock Mode Do? Lock mode keeps you from accidentally turning your iPod on or off.
This helps save battery life if you have it locked while it's asleep.
It prevents your music from turning off if you've put your iPod in your pocket. However.
it's not an advanced security feature -- anyone can bring your iPod out of lock mode if they know how.
Lock Symbol When you see the lock symbol on the top of your iPod touch's screen, it always means that the iPod is in lock mode. There's no other reason for that symbol to appear. If it appears and your iPod is not in lock mode, just turn your iPod touch off and then on again and it should disappear. b> Entering Lock Mode b> Press the Sleep/Wake button on the top right of the iPod touch. You may need to hold it down for a couple of seconds. Don't hold it down for too long, as ten seconds or so will force a restart and turn your iPod completely off and then on again. b> Exiting Lock Mode b> Press the Sleep/Wake button again, and wait a moment for the screen to light up. You'll see a slider bar that prompts you to slide it to wake up and unlock the iPod touch. Put a finger or thumb on the solid part of the slider, then slide your finger to the right. This gesture is simple, but might take a couple of tries. You need to tap firmly on the slider, then keep contact with the iPod as you slide to the right.

railbird56, Common problem for ALL BRANDS of "cold-cahtode-fluorescent-lamp" back-lit lcd monitors! Here are your options!!! Cheapest to most costly!! 1. Warranty repair. 2 DIY repair???? 3. Local or distant repair. 4. possible old + cash swapout with Hannspree for refurbished same model?? 5. Trade-in for new wide screen. My best guess on your monitor (no history) is that the unit's SMPS is in partial or full shutdown mode during it's black screen moments. How much do you know about "electronic ballasts" "switch-mode-power-supplys" and how to repair them?? 12fixlouie

mccampbell71 Probably a failure of inverter circuit(dc to ac 600-1100vac) to light-up (sustain) "cold-cathode-fluorescent lamps" causing the "switch-mode-power-supply" to go into full or partial SHUTDOWN mode. Black Screen of Death strikes again!!! The Question I have is why did you BUY a "black-brick" supply? Did the other one fall out of the car or get run over by a train? Only you will be able to make the decision of to REPAIR or Trade-in for new. You are no different than 5000 others worldwide (all brands) who have monitor's with BSOD! Yes, some (75-90%) can be saved to work 1-3 more years! Read some of my other responses in my profiles (12fixlouie aka louie12fix) to learn of the options you have open to you. Bye for now 12fixlouie If this info was of some use please rate on fixya.

This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.

If you don't see an image with the flash light, then it could be the main logic board.
