Question about HP iPAQ HX4700 Pocket PC

1 Answer

Backlight problems Intermittently, but most of the time, when I turn off my HP4700, the PDA does not turn off, but the backlight does. I have set the power to turn off the device after 2 minutes, so it is not a major problem. I get a similar problem on turning on, namely, most of the time the backlight is turned off, so I have try and find the light slider in the dark. I have checked the button to turn on the backlight when a button is pressed or the screen tapped but it doesn't happen. Any ideas?

Well if you hold the power button too long the PDA will just turn off the backlight. If you just hit the power once and not hold it then it should shut off (of course it really never "shuts off" completly because if it did then you would loose all your data).

How to fix my Samsung tv ..picture goes in and out intermittently

The inverter board is responsible for the backlight so you can see the picture. If the picture just goes off intermittently then that means that the backlight is being turned off. And since the inverter board powers the backlighting you might want to look there.

How to turn off the blue light

Normally, i'd say "Don't violate any traffic laws, wear your seat belt, and don't call attention to yourself, so that the Boys in Blue don't pull you over.". However, since you show a cell phone, pda, ect. I would say this is your solution. Go to Menu, Tools, Settings. Backlight, and scroll to adjust the time the backlight is lit, or to off. Or consult the manual or any store who is your Carrier, and ask for their assistance. Possibly a search on the Web at Google or Bing with your phone/pda name and model # will let you look at, read, and maybe download and print a manual for your use. But, given the complexity of the device in your picture, be prepared for a lot of ink and lot of paper if you want Adobe to print it out for you. Probably over 200 pages. Looooong print process. I would go to my Carrier's store or Kiosk and ask the Techs and Sales Reps there. Good luck. Kindest Regards, Slats.

The wired keyboard backlight turnes off too quickly

You would need to go into the Setting Menu and find the Backlight or Power setting to lengthen the display and keypad backlight times. Just know that your battery life will decrease the higher the settings especially since it is a VGA screen.

You can configure iPod so the backlight turns on for a set amount of time when you press a button or move the scroll wheel.
To access the backlight settings:

No backlight

A couple things to try:

1st check the backlight settings

Turn on Backlighting and Control Brightness To use your device in dark environments, enable the automatic backlighting feature:
  1. From the Jump screen, press MENU t02003-15.gif then select Settings > Battery & Display.

  2. In the second group box, select the Turn on backlight when using device check box.

  3. Highlight, then select the Brightness slider to open it for editing. Roll the TRACKBALL right to increase brightness; roll the TRACKBALL left to decrease brightness. After you've made the adjustment, press the TRACKBALL to exit edit mode. t02007-55.jpg

  4. Select the length of time you want backlighting to stay on from the Turn off after pop-up menu.

  5. To use the device's light meter while the backlight is on, select the Use ambient light sensor check box.

  6. Press JUMP t02003-14.gif to return to the Jump screen and save your setting.
Now, when you press any button or key, or flip open the screen, backlighting will turn on for the set amount of time. Note that as long as you press a key or button before the set time elapses, the backlight will stay on.
  • Even if you have not selected automatic backlighting, you can turn on backlighting at any time by pressing MENU t02003-15.gif + JUMP t02003-14.gif . The backlight will remain on for the time specified in the Backlight Turn off after pop-up menu.

  • When in key guard mode, you can turn on the backlight by pressing the RIGHT SHOULDER t02003-66.gif button.
If it still does not work, then you can try resetting the flex cable to the lcd.

Reseat the SidekickFlex cable

If that doesn't fix it then a new lcd assy will take care of the issue. they run about 45 dollars on ebay.
