Random Blue Lines

I have much the same problem as another person did on this page. 1. When the T.V> is plugged in it come on automatically. 2. There are blue lines racing all over the screen (like x'sfrom one corner to the other) looks like the old Vsync. 3. No volume / menu / video select will change but still blue lines everywhere other than one setting. I have pulled out the power supply board and saw the 3300 uF capacitor mentioned in the other post but was not sure that it was bad / not leaking. not sure where the pico fuse is exactly as i have no diagram and not much exp working with TV's. I found that the power supply was available from www.bestbuy.com for 69$ but wanted some opinions on this before i spend money i dont have to spend. Do you think replacing the power supply will fix this or have you ever seen this before? Thanks in advance. sorrowfull APEX T.V. owner...

    O.K. The voltages are listed there on the board. I will measure them tonight and if any of them is off then I guess without a doubt it should be the PS. I also found a circuit diagram of it as well. I will let you know what I find.

You should'nt replace anything untill you get a multimeter and measure the voltages on the Power supply PCB. Call Apex in your owners manual and see if they will supply a service manual so you know what the voltages are suppose to be. Or that manuel is avail as a download at http://www.servicemanuals.net/ for 15.00 bucks! Then you will get a better idea on what needs to be done , instead of shotgunning the repair. Good Luck

How do I bypass administrator password on my Dell Latitude d 630 tag number H7YT8F1 - 595B...PPLEASE HELP

not told any history at all (sad face)
1: bought it like this, (send it back)
2: kids messed it up (brats?)
3: out of the blue it does this ,not before, (CMOS DEAD)

dell.com
ask them,
or learn to hack using google
google "Dell bios Password reset back door"
and pay the hackers.

or send it back to seller or ask them for PW
out of the blue.?
the COIN cell CMOS is dead and when dead BIOS goes MAD
it endlessly lies to you in fact and for a fact is random lies.
is that fun? no and must be replaced.

2007 PC no PC coin cell works that old, H3LL same with big BAT.

page 70 in your manual states and I quote to you new is

If you forget any of your passwords, contact Dell (see "Contacting Dell" on page 140). For your
protection, Dell technical support staff will ask you for proof of your identity to ensure that only an
authorized person can use the computer.(end)

Why blue lines when document printing?

You need to do a head clean you should be able to find this in maintenance section of the printer program.
They get a little dry spots or dirt on the cartridge.
This is a ink eater so uses a heap of ink could take 2-3 head cleans to clean it.

The Drive light flashes and the car loses power and sometimes won't start.

It is either your Vehicle Speed Sensor (easy to change) or your Automatic Transmission Computer (capacitors burn out on these boards, there is a fix for this too, the picture is at the bottom of this page). You need to diagnose by removing the lower right plastic kick panel on the passenger side. There you will find a blue plug. With the car OFF stick a paper clip, wire or stuff the plug with foil to make electrical connection so that the two terminals are touching. Then, turn the ignition to ON (not enough to start it though, just power it up). When you do this, count the blinks in the "D Light" or count your blinking Check Engine Light. Both are different but can refer to different things wrong with your car. A long blink is the first number and the short blinks that follow are the second number.
So imagine this as being 14 : ___ _ _ _ _

Below is a decoding chart:
