Question about Pantech Duo Smartphone

2 Answers

Many probs but mainly I am looking for a way to open the case

1. My backlight stays on as long as the battery is in the back - even when its not in windows mobile.
2. My screen has started to go into 256 color mode (think the lcd ribbon has come somewhat loose). How do I go about opening the case - I removed 4 screws on the bottom under the battery - but the top part by the camera will not 'pop' out, is there some magic I'm missing here? I just want to take it apart so I can check the connections.

Thanks!
Tim

Well, there are screws on all 4 sides of the top lcd panel, and the keyboard panel, but the slider doesn't slide in that direction so they are always hidden. I figured you have to start from the bottom removing layer by layer. Can't get the camera point off and I'm scratching the case in the process.

How to increase battery life in LG GT505


Feeling tired that after surfing the web or playing a few games, the battery is halfway through to being dead?
So this Tip is for you!
What we're going to do, is put every setting on the minimum so that it doesn't waste battery life that much when you're just typing a SMS.

1 - Open the Menu and click on the last icon (on the right bar) on the bottom. - Settings

2-Open Phone Settings, and slide the Power Save button to turn it ON.

3- Now go back to Settings and go to Screen Settings and choose Brightness. Set it to 0% and Save it (click Yes even if it tells you that you are changing the Power Save Settings)

4 - (Optional) If you don't mind your phone turning off the backlight real quick, you can change the amount of time it stays on, but if you send or read a lot of messages, it can become a bit annoying, so it's really up to you! Anyway, in Settings, choose Screen Settings, then Backlight, and choose whatever time suits you. Keep in mind, that the lower the time stays on, the more it saves up battery life.

Imagine you just made a phone call, then put the phone on your pocket. For some time, it's backlight is on for a long time, maximum brightness and you're not even looking at the phone. That's a waste of battery power!

Using those new settings, you can get up to 3 days battery while playing a fair amount of games!

Why are all the lights on LCD screen on?


How to troubleshoot and fix video problems
Here are some tips and tricks for troubleshooting and fixing laptop video problems. Video issues are very common within portable computers and with the following tips you should be able to detect and eliminate basic laptop video problems.
Laptop LCD screen has a faint image.


all-lights-lcd-screen-4ztirbadqll2ypvmakqp10pq-2-0.jpg
Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the backlight stays off even when you open the LCD screen or turn on the laptop. The switch turns off the backlight when you close the LCD display to save the laptop battery power. Check the LCD lid close switch. Usually it is a small plastic pin located close to the LCD hinges. Try to tap on the switch a few times to turn on the backlight. If after tapping on the LCD lid close switch the backlight stays on, you fixed the problem.
It is also possible that after tapping on the LCD lid close switch the backlight works fine, you see a normal video on the screen for some time and then the backlight turns itself off again. In this case I would blame the FL inverter board. Try to reseat cables on both end of the FL inverter to make a better contact between the cables and the FL inverter board. If it doesn't help I would try to replace the FL inverter board.
Laptop LCD screen is solid white color.

Most likely it is just a bad connection between the LCD display and the system board. I would try reseating the video cable connector on the back of the LCD screen first and check if it fixes the problem. After that I would try reseating the video cable connector on the system board. I would also try reseating cables if there is no video on the LCD screen at all.

http://www.laptoprepair101.com/wp-images/bad-laptop-video/washed-lcd-image-1.jpg
Try to connect the LCD screen to an external monitor. If the external video is fine, you have a problem with the LCD screen or the LCD video cable. You can try to fix the problem by reseating the video cable on the back of the LCD and on the system board.
If you see the same garbled video output on the external monitor most likely it is not the LCD screen problem. In this case the system board (with onboard video) is bad or the video card is bad.

GOOD LUCK.

I have a Cornea 1702. It just stopped working altogether. It doesn't even show the menu nor does it search for a signal as it used to while scrolling thru options or select input! I think it's fried, but I...


OK, first off, I'd like to say that I've never worked on the Cornea 1702, but most monitors follow similar designs, especially generic brand monitors.

So there are a few things I need to know:
What exactly happens when you press the power button?
Does the power light come on?
Does the screen's backlight come on?
Does the screen just stay black as if its turned off?

OK, so if the power light turns on, but the screen stays black with no backlight, the problem is either the monitor's power board/inverter or the backlight itself.

If the power light turns on and the backlight turns on, but the screen stays white or black, then there is most likely a problem with your monitor's main board or a problem with the connection from your LCD panel to your mainboard.

If the power light never turns on, then most likely you have a bad power board.

In general, I doubt it would be cost efficient to purchase a replacement board if they are defective. It would probably be both easier and cheaper to buy a used monitor on craigslist for $30-$40.

You might be able to fix the power board/inverter or backlight using the following methods, provided that your monitor doesn't use an AC adapter for power:

If you feel adventurous and want to open up the LCD, I'd unplug the monitor. Then be sure to ground yourself and get rid of static electricity by touching some metal object near you. Then take apart the monitor.

To open it up, you need to first remove the stand, then unscrew all screws on the back, then pry apart the casing at the seam with a small flat-screwdriver or something like that. That should get you into the casing, then you just have to look around and see where to go from there. You may have to remove other covers to get to the powerboard. Also, I wouldn't touch the cable between the monitor and the main board, just in case.

You then need to visually inspect the powerboard. Most likely you will need to replace bulging or bad capacitors on the power board. They will likely have voltages between 16-25V and capacitances of 470-1000uF. If you notice bad capacitors, you will need to desolder them from the board and solder on new compatible ones. You can go with higher voltages and capacitance, but nothing lower than whats there already. You can buy capacitors cheap on eBay or pick them up at RadioShack for $1-$3 each. If you see bad capacitors, replacing them should solve the problem.

If the capacitors look fine or replacing them doesn't solve the problem, the problem may be with your backlights themselves. If you are able to test them, that would be best. Replacing them is a pain as you will have to disassemble the LCD panel itself to get them out. You will then have to replace them with compatible backlights of the same size, which you can salvage from similarly sized broken monitors on eBay.

Keep in mind that the suggested actions above are for individuals with some experiences in soldering and repairing circuit boards or LCDs. Also be sure to wear anti-static gloves or wristband and keep the monitor unplugged when performing the above stated actions (except of course when testing voltages).

If you're not comfortable doing that, then find someone with experience in fixing or opening electronics and/or PCs. Good luck, hope it works out!

Display flickers and darkens


There are two main possibilities.

1) The cable between the inverter and backlight burn on the screen is loose. You will need to open screen to reseat it.

The other is that the inverter or backlight is dying and your display will stay dark sooner or later.

If you find this helpful please rate so.

Thanks

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.
