My Actius has begun having trouble displaying colors properly. Random red and blue pixels are displayed within color fields. Flesh tones and greys often have lines of blue pixels within them, while certain white fields have extra red pixels stuck on.
At first this seemed to be a software problem and happened only occasionally. Now it is continuous.
I am getting red dots on my Sharp Actius PC-AL27. It's doing it on any pictures on the screen. It would only do it once in a while and when rebooted seemed to help. Now its like this all the time.I am getting red dots on my Sharp Actius PC-AL27. It's doing it on any pictures on the screen. It would only do it once in a while and when rebooted seemed to help.

Does the same symptoms reproduce themselves on an external monitor. If they do you have some faulty RAM or Video RAM possibly. If not then you might have a faulty LCD panel.Does the same symptoms reproduce themselves on an external monitor. If they do you have some faulty RAM or Video RAM possibly.

From what you described, it seems as though your LCD panel is going bad or the inverter board is bad. Does it change colors if you were to reposition (tilt) the LCD back and forth in either direction?

Color temperature refers to how red (warm) or blue (cool) the color palette is. This control helps you to adjust the color settings on your TV. You can change the color settings by following these steps:
- Using the TV remote, select settings and look for a menu item labelled video or picture. - Select Color Temperature. A slider should appear that allows you to slide between cool and warm colors. The colors might also be labelled red or blue. - Slide the settings away from red/warm and towards blue/cool using the remote control. You can leave the slider at the point where the color is most pleasing to you.
If you mean you have a pixel that is stuck on and is always red, there's nothing you can do. The only cure is to replace the display. LCD displays sometimes will have a pixel (sometimes several pixels) that doesn't work properly. The manufacturers know this, and as long the display falls within their specifications for what's acceptable, they don't see anything wrong. These specs include the total number of bad pixels, the number of bad pixels that can be clustered together, and where they can be on the display. If you have just one or only a few bad spots, they won't do anything for you. If other problems develop, such as a whole row or column goes bad or a section of the display fails, then you can see about having them fix it if the warranty is still in effect.
I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.
"Plasma flat screen technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each."
You need a 512MB
PC2700 DDR 333MHz SO-DIMM for a laptop (200-pin). The
manufacturer I think doesn't specifically support anything over 512MB. But the RAM is standard and I doubt there is any need to buy it directly from Sharp. The laptop only has one upgradable bay so you may not be able to upgrade past 1.25 GB.
One of the memory covers is not removable, if I remember correctly, that is the one under the keyboard. So the one you update is a panel on the bottom.
I have read that you have a realtek audio card. To get these drivers goto http://www.realtek.com.tw/DOWNLOADS/
and choose AC'97 Audio Codecs (Software), accept if you do on the next page, wait a second, and the NEXT button will go red. The click on it. on the next page choose your operating system drivers. Get the accompanying software on that list.
And in case you need the high defintion drivers they are on this page also. http://www.realtek.com.tw/DOWNLOADS/

There was a post I read on a notebook forum site that deals with a BIOS problem with the Sharp Actius PCAL27 from a guy named fixyourlaptop AT yahoo DOT com. He stated that he was a Sharp tech, and that the main problem with the AL27 is not the battery, but the BIOS.
There is apparently an issue with these BIOS that causes the power usage of the battery to show incorrectly. I purchased my laptop over three years ago, and just recently updated the BIOS sent me by this fellow, and my laptop battery discharges properly. It still only has about an hour of life but this is the first time it ever worked right.
You can email him for the fix at the above address. Just put in the subject line SHARP LAPTOP AL27 BIOS FIX. He is legit and the fix worked like a charm.
If you want to read his post just do a search for the above (properly formatted) email address on google.
