LG HDTV Vertical Grey Bars

We have an LG HDTV and, quite sudenly, the HD cahnnels delviered by Dish TV no longer stretch to fill the screen. There are two grey bars, one on each side that bracket the image. The image is HD. If I switch to a non-HD channel, the image fills the entire monitor space. I ahve played with the settings on the TV, amplifier and Dish box. They are all set to 16:9. IF I modify the settings to 4:3 the widthtof the grey bars changes, but no setting will make them go away.
I have tried unplugging everything (I use HDMI from the Amp to the TV, and Dish box to Amp). have also killed hte power completely and rebooted. Nothing resolves the issue.
This started about one week ago.
Any ideas?

Where are these lines? In all apps - any time you use the iPad they will appear?

Vertical scroll bar disappears on the timeline?

After I use the vertical scroll bar once it disappears and I am unable to scroll. If I click the film strip on and off, it comes back. Is there a way to always keep the scroll bar visable on the timeline?

That has got to be a bug. Go to the Motion menu and Provide Motion Feedback... !
Otherwise, you can scroll with your mouse. I use a mouse with a scroll wheel, but I think I remember the magic mouse has a scroll gesture(?).
You can make the layers smaller by mousing over one of the lines in the layers list to the left of the timeline. The cursor should change to a double-pointed arrow. Click and drag the layers smaller.
You can open the timeline window wider by mousing over the Timeline top border, and click drag to make it larger.
I use this feature so rarely that I had never noticed before. When the scroll bar does appear, it's not "fully formed" either -- just a grey bar -- no resize controls on the ends at all.

I have a macbook pro 10.6.8. The screen displays vertical grey lines how do i fix it?

I have a macbook pro 10.6.8. The screen displays vertical grey lines. I tried Crtl.command.eject... Did not work. I tried Command.crtl.p.r. way; Didnt work. What is wrong with my mac and how can i fix it?

NVRAM reset is command, option, P and R.
Restart the computer and immediately hold the four keys down. Keep holding the keys down, and let the Mac chime three times, then release the keys. Be patient it could take some time.
That being said what you describe may be a hardware issue, so the NVRAM reset probably won't work.

Artifacts between Logo and Vertical Menu Bar

See http://www.ottawapatentagency.com
Artifact #1: a light grey dot at the joint between the logo and the vertical menu bar, on the right hand side.
Artifact #2: on mouse over 'Home' - the top menu item of the vertical menu bar - there appears a light-colored, 1-pixel separation between the logo and the vertical menu bar.
The logo is a standard gif and the vertical menu bar is a standard spry menu bar, I am puzzled.
Anyone has a solution?

You could try adding the following code above your closing </head> tag:

Also, it looks like you need to add closing brackets to the following two lines:
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon"
<link rel="icon" href="/favicon.ico" type="image/x-icon"

At times when dragging the vertical scroll bar my computer screen oscillates up and down for some time before going blank or not responding to any clicks requiring a forced system restart. What is wrong?

Hi,
Suddenly while working with Firefox if I happen to drag the vertical scroll bar, a very abnormal behavior occurs. My screen dances up and down for a short time before either going black or getting restored but with no clicks working. The only way to resume is to force a restart of the system.
Any help would be deeply appreciated.
Thanks and Regards
Deepak

That didn't work. On trying to install a new driver I got the error the graphics driver could not find compatible graphics hardware. Is there anything else that can be done to at least prevent the hanging of the computer even if it means less features from Firefox being available?

In my macbook pro sees in the screen very wide a vertical black bar and it does not let see what this underneath that bar

Take it in for service. Your screen probably needs to be replaced.

Question on vertical scroll bars in JScroll Pane

Hi,
I managed to display my chat program with a vertical scroll bars by using JScrollPane. Every time some on types a line, this is appended to whatever was previously in the JTextArea (the JScrollPane has a JTextArea in it). Even though this works fine, when the dimension of the JTextArea is full with text, one has to scroll down to see what was the last line of text that was typed.
Is there a way to make the verticall scroll area alwas scrolled down (I mean, scrolled to the bottom so I can see new incoming text without manually having to scroll it down?)
Thanks!
Cecilia.

You might try adding a properties listener to the JTextArea listening for a "resize/size" property change and when it does, force the scroll bar to go to max.

Vertical Scroll bars in analysis - View all rows

Users want to see the whole report displayed in one page with only a vertical scroll bar. They do not want the up/down arrows. Is this possible in OBIEE?
Thanks.

To implement the solution, please do:
1. Change instanceconfig.xml file in <biee11g_install>\instances\instance1\config\OracleBIPresentationServicesComponent\coreapplication_obips1 as following
<Views>
<Pivot>

<DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>

<DefaultRowsDisplayedInDownload>2500</DefaultRowsDisplayedInDownload>

<DisableAutoPreview>false</DisableAutoPreview>
<MaxVisibleColumns>5000</MaxVisibleColumns>
<MaxVisiblePages>2500</MaxVisiblePages>
<MaxVisibleRows>500000</MaxVisibleRows>
<MaxVisibleSections>5000</MaxVisibleSections>
</Pivot>
<Table>

<DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>

<DefaultRowsDisplayedInDownload>2500</DefaultRowsDisplayedInDownload>
<MaxVisiblePages>2500</MaxVisiblePages>
<MaxVisibleRows>500000</MaxVisibleRows>
<MaxVisibleSections>5000</MaxVisibleSections>
</Table>
</Views>
3. Note the new elements added are the following to both <Pivot> and <Table>, the Pivot part controls Pivot view, and Table part controls Table View, my testing was done with Table View.
<MaxVisiblePages>2500</MaxVisiblePages>
<MaxVisibleRows>500000</MaxVisibleRows>
<MaxVisibleSections>5000</MaxVisibleSections>
4. Restart Presentation Server from EM, then run your request, do excel export to verify.
Thanks...

How do i customize the states in a vertical menu bar?

i see that it is possible to change the states for a horizontal venu bar, but i can't get it to work for the vertical one. please tell me we can edit the states in a vertical menu bar.
valerie

Yes, you've hit a bug in Muse, that will be fixed in the next release.
The bug happens when you have a gradient fill for the default state, but no gradient fill for your other state. The vertical menu has this look by default. You can work around it by removing the gradient in the default state, or adding a gradient for the other states.

On every website, my right vertical scroll bar is missing and all of my Toolbar bookmarks unless I minimize the window, click "view" and "full page." How do i get it back to NORMAL?

When I hit "full page" the right vertical scroll bar re-appears, but my bookmark toolbars, my bing bar, and pretty much the entire top 2 inches of my screen disappears. When all of these things are showing, the right vertical scroll bar disappears, and the entire webpage shifts to the right, so I can't see most of the right side of the page. How do I fix this?

HP LaserJet 2430 Prints vertical grey bands

While printing, some characters from each line are repeated at 3 inch intervals along the length of the paper. This happens at about 2 inches and 7 inches from the left margin and appear as two vertical grey bands on the printout (portrait mode). The widths of the bands are approximately 2 characters and 8 characters.
For example when a single line is printed the two characters at 2 in and about 8 characters at 7 in from the left margin repeat at 3, 6 and 9 inches down from the printed line and their intensity of the printing decreases. The same happens with each printed line creating two bands.
It appears the electrostatic mechanism that deposits toner does not get properly cleared after printing each line. The left over electical charge keeps the carbon particles at those (2" and 7") locations subsequently depositing at each rotation of the roller (approximately every 3 inches along the length of the paper)
I followed all the five steps (suggestions) by HP but the problem persists. I would appreciate any help in resolving this issue based on your e experiencewith any HP LaserJet printer.
1. Power is an important part of LaserJet printing and inadequate or marginal power supply can at times cause this sort of issue to occur. Please
plug the printer directly into a wall outlet to eliminate the possibility of power issues caused by other power devices. Please turn off the printer. Remove the printer power cable and connect it directly to a wall outlet. Turn the printer ON.
2. Please ensure that the print media meets the HP media specifications.Please refer to the document at the following URL for information on media specification. HP LaserJet 2400 Series Printer - Paper (Media) Specifications:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00244086
3. Over time, particles of toner and paper accumulate inside the printer. This can cause print-quality problems during printing. Cleaning the printer eliminates or reduces these problems. Clean the paper path and print-cartridge areas every time that you change the print cartridge or whenever print-quality problems occur. Try to keep the printer from dust and debris as much as possible.
Please refer the following document for the cleaning procedure for the HP LaserJet 2400 series of printers: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00243502 After running a cleaning page, print a page and check if the issue persists.
4. Do a cold reset on the printer:
To perform a cold reset, please follow the steps given below:
1. Turn the printer off.
2. Turn the printer on. When the printer begins its memory count, press and hold down the select button until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds.
3. After the message SELECT LANGUAGE appears on the display, press the Up Arrow button or the Down Arrow button until COLD RESET is highlighted.
4. Press the Select button. The printer performs a cold reset and then continues its power-on sequence.
5. Check all I/O settings and reset any customer-set printer configuration values.
5. Do a Firmware update on your printer. You may refer the following document for information about upgrading the firmware for the HP LaserJet 2400 series of printers:

The problem looks like the fuser. Bad spot at 2 3/16 inch from the left.
Part on order.

T43p with one vertical white bar 1/2" in width 3" from right side of screen

I have a T43p with this vertical white bar that is new as of an hour ago. Not sure where it came from or how to fix it. I don't think anytihng is loose because I wiggled and pushed on every part on and around the monitor to see if it would change color or flicker at least a little. No change was noted. I also restarted and no change. External monitor shows no signs of this bar so it is not due to programming. I believe is is all due to hardware. Any ideas on an easy cost free fix? any help woud be awesome.

Welcome to the forum!
I don't believe that there's a cheap fix for an expensive machine such as T43p. Do you have any warranty left?
Have you run PC-Doctor on all video aspects of the system?
Good luck and let us know.
Cheers,
George

Grey bar on top of page onYouTube ios safari.

Ok, so suddenly I have a big ugly grey bar on top of the page when I try to look at youtube on safari on the ipad.
The grey bar is displaying the YouTube app icon, with a button to open the app ( because I have the app installed, I imagine it would say install if I didn't.)
Now if I wanted to use the app, guess what, I would. I prefer to look at youtube on my browser.
The problem is that on the grey bar at the top left corner is a tiny (X) button to dismiss the grey bar, which I would very much like to do, but it is impossible because I cannot press the (X) because it is positioned in such a way that its like there is no button there. I tried repeatedly to close it, instead, it just keeps opening the YouTube app, which I don't want to do.
Is this bar going to remain on safari all the time when I want to look at youtube?
I don't understand why I'm being pushed to use the app. I know I have it, I don't need reminding, I'm choosing not to use it, i prefer safari version to app, why is safari doing this?
I feel like Apple is trying its hardest to annoy everyone and ruin what was a slick seamless service before Steve jobs left the game.
There are several other little annoyances like this that I can't even be bothered to get into, all beginning immediately after Steve was out of the picture.
Meanwhile, chrome browser for ios is displaying everything beautifully and is becoming my main browser on ipad.
Are they trying to push me toward the Google phones and tablets, because it's working.
Does anyone know how to dismiss this irritating grey bar?

Hi all,
I am having trouble getting some things done by changing the html/css
we use apex 4.1 and sapphire theme 17
all I want to do is to decrease the size of the bar on top of the page and get rid of the ugly border at the bottom of it
this is code you find on page 0 , region
<STYLE type="text/css">
#topbar {
border-bottom: 0px;
#header {
height: 15px;
</STYLE>getting rid of the bottom border ok
however as soon as I make #header smaller than 50px, the whiole layout gets messed upThe layout is behaving exactly as requested. What you're seeing is not the "layout getting messed up", it's the background image with a fixed-size "header" applied to the page <tt>body</tt>, visible through transparent elements that are now in positions not anticipated by the designer of the theme.
You need to shift the page background up with respect to the viewport to allow for the 35px difference in <tt>header</tt> height between the theme's 50px and your 15px:
body {
background-position: 50% -35px;
}Note that this introduces a subtle change in the header as the gradient fill now appears to start with a darker shade.
