Yes a new LCD might fix this issue.but it could also be a bad display circuit.

Well your on the right track I would say it's your LCD because your video chip wouldn't make black circles I don't think. The pink and black lines are a symptom of a LCD that has been broken and the circles sound like someone squeezed it to pick it up by the screen maybe. That would be for your venders warranty department to figure out though. If you really want to know you could buy a cable to hoot it up to an external video source if the display is fine, it's defiantly your LCD.

A green line just appeared on screen. how do I get rid of it.


Sad to say, you're stuck with the line. Solid color lines that go vertically or horizontally across the display are because of driver circuit failure in the display panel itself. There's a lot of electronics built into the display to control the individual pixels that make up the display. Sometimes those parts go bad and light up a whole row or column all the time. There isn't any way to get into those parts to repair them; the only way to fix the trouble is by replacing the display.

You can continue to use the laptop and just get used to the line. Using the computer this way won't hurt anything or cause further damage, but it's annoying. Or you can consider replacing the display. It's not difficult to do, and the cost for many displays is reasonable. Many sites show the process for specific brands and models of laptops, and eBay is a good place to look for replacement displays. And of course, you could use this as an excuse to replace the computer if you've been wanting a new one.

Thanks for using Fixya!

When I press ON, my calculator screen displays a couple random numbers and letters scattered across the screen, including a solid vertical line in the upper right corner. As soon as I push any key, the...


There are three possible solutions here. From what you are describing to me, you say the screen displays a couple of random numbers and letters, including a solid vertical line in the upper right corner, are scattered across the screen? Sounds like you are still in graphing mode. There is nothing wrong with your batteries and changing them won't help because I already know that you didn't change the CR Lithium Battery. This is the "memory card" for the TI-83 Plus. If you don't change that, when you insert new AAA batteries in the calculator, the memory has not been deleted. You probably don't remember, but the calculator remembers the last problem that you did, which was a graphing calculation. Try pressing the "Graph" button and the calculator will go back to function mode. If this doesn't work, try resetting all the memory.
  1. Remove a battery from the battery bay.
  2. Press and hold the CLEAR button while re-installing the battery.
  3. While still pressing the CLEAR key, press and hold down the ON button. If the home screen displays, release the keys.
  4. If the home screen is displayed, press 2nd MEMto display the memory menu.
  5. Select 7:Reset to display the "RAM ARCHIVE ALL" menu.
  6. Press the right arrow twice to display the "ALL" menu.
  7. Select 1:All Memory to display the "RESET MEMORY" menu.
  8. To proceed with the reset, select 2:Reset. The message "MEM cleared" is displayed on the home screen.
If this doesn't work, try changing the CR Lithium Battery. It is located in the battery bay at the top with the cross-head screw in it (It says BACK-UP BATTERY). It tells you what type of battery it takes and how to insert them in. I hope these possible solutions help. If all of them don't, then the only other thing I can think of is that it has some internal part alignment issues or a cold soldering iron blob, on the inside of the calculator. I saw one time on the Internet that cold soldering irons can sometimes make electronics not work properly.

Are the lines all the way across the screen? or just a few? Solid black - or trannslucent?

Like this??

Horizontal drive has either data, voltage, or control problem from the pixel registry circuit......get it serviced before the problem spreads causing further damage.

However, in all likelyhood, the panel itself is bad. The Bravia line has had a bad rap about the faulty displays, and at $1800 replacement (plus labor) - it may be time to call SONY direct to complain!

Thanks!!

Lines across the LCD screen


Two things can cause lines across the LCD either horizontal or vertically. The first (and most likely) is a small crack in the display wafer. LCD stands for Liquid Cristal Display. They are very fragile and can be easily damaged if dropped. I broke one in my pants pocket.

The second would be if a pin on the ribbon cable (to the LDC wafer) was not making good contact. If you disassemble the camera it is possible to clean the contacts using contact cleaner (or alcohol). Only attempt this is you are willing to replace the camera if you don’t put it back together properly.

Saved images to the internal memory or to the optional xD-Picture Card


The internal memory and the xD-Picture Card cannot be used at the same time. When the card is inserted the internal memory is disabled. When you want to use the internal memory, remove the xD Picture Card. The LCD display will indicate that images are saved to internal memory by displaying [IN] in the lower right corner of the screen. When using the xD-Picture Card the camera’s LCD will display [xD] in the lower right corner of the screen. These indicators are displayed just above the number of available frames.
