Sounds like a bad solder connection on the CRT driver board, or around the high voltage transformer. Also a possible bad connection in the Y/C circuit. If you have no TV repair experience, play it safe and have a pro give it a look, as a simple problem can turn into a major one if one does not know much about the item. Good Luck

How to disable ipod


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.

Hannspree HF229H will not stay on


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

My Acer AL1714 monitor was given to me, the person that gave it to me said last time the last time it was connected it work but the monitor had been stored for about 2 years. So I bought a 19V-2.3A power...


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.

Starlogic 20 inch widescreen monitor screen keeps going black


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.

SCREEN WON,T STAY LIT UNLESS I TOUCH IT


You are simply in blackout mode. This is so at night you aren't blinded by the glow of a screen. Here are instructions right from the manual to turn on or off.

Blackout Mode On and Off
When Blackout mode is turned on, the monitor display will turn off to
reduce power consumption.
This additional power enhances the sound quality.
1 Touch [VISUAL] on the main source screen.
The VISUAL selection screen is displayed.
2 Touch [OFF].
The backlit-display portion goes out.
3 Touch [OFF] again to cancel the display backlight.
To make the setting, set to “Setting the VISUAL Touch Button” (page
34).
If any button on the unit is pressed during Blackout mode, the
function will be displayed for 5 seconds to show the operation before
returning to Blackout mode.
While the backlighting is turned off, the function indicator

Nothing appears on the LCD screen. What should I do?


The camera may have shut off automatically to save power. Press the POWER button to turn it back on. Also make sure the mode dial is turned completely to the desired mode. When the camera is connected to a computer, the LCD screen is disabled. When it is connected to a printer, press any button to display the print progress screen. After a moment, it disappears again.
