If your Samsung TV has a VGA input then connect a VGA cable to the TV and the other end of this cable to the video port on your Dell laptop. Turn on your TV and select the VGA (computer) input then boot up your Dell laptop.and then the video data from the laptop will automatically divert to the TV.
You can toggle between the TV and laptop LCD screen by holding down on the Fn key and press the F8 key.

When you connect the vizio try changing the resolution settings on your laptop to see if that makes a difference. Could be that your video card output is not really compatible with the higher requirements of the Vizio.

Let's start with two small primers first;

A) An LCD screen cannot produce light. It needs an additional light source. A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)
The Dell Inspiron 1564 Notebook PC can come with either a CCFL backlight, or LED backlighting.

http://www.laptopscreen.com/English/model/Dell/INSPIRON~1564/

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[ Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.
Basic example. Look at the last 9 photos,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/ ]

A screen Inverter is used to convert the electricity from the laptop, for the LCD screen, and Backlight.
For LED backlighting a screen Inverter may not be used.

B) For a Dell, video cable is Display Cable.
LCD screen = Display Panel
Switch Cover = Power Button Panel
(Cover that is a strip of plastic essentially, that is above the Keyboard, and below the LCD screen. Has Power On button)

Display Cable:
The display cable attaches to the motherboard, in an area under the Power Button Panel. (Above the F2 and F3 key, approximately)
It then routes under the left Hinge, and up into the Display Panel Assembly.

From there it attaches to the screen Inverter, if used, and to the back of the LCD screen.
A example of the cable,

http://www.ebay.com/itm/DELL-INSPIRON-1545-LCD-FLEX-CABLE-LED-R267J-NEW-/370491513861?pt=US_Laptop_Screens_LCD_Panels&hash=item564303dc05

The cable may become pinched in the left Hinge. This can cause pulling on the cable, and/or damage.
Pulling may cause loose connections of the cable. Loose at the motherboard side, or LCD screen side.

Doesn't take much of a loose connection to get issues like what you are seeing.
In fact it may be so minute (My-noot) that it won't be visually seen.
The ONLY way to be assured the connections are tight, is to PHYSICALLY check them. Try to plug them in tighter.

This means checking the display cable on the motherboard side, and LCD screen side.

http://support.dell.com/support/edocs/systems/ins1564/en/sm/powerpan.htm#wp1061007

The Power Button Panel contains the Power On button/switch.
It can be removed, and laid over so that the motherboard connection can be checked, with the Power On switch still attached. This way after physically checking the connection, the laptop can be turned on, and display checked.

[Lay the Display Panel Assembly back as far as you can. Suggest covering screen with soft cloth, or suitable device to protect screen.
Screen has to be handled as if it is good, until diagnoses shows differently.

If the Power Button Panel cannot be laid back far enough, to get out of your way, unplug the Power Button cable. Plug back in to check display.
ALL power removed BEFORE disassembly.
Replace Battery, and AC adapter (Charger) when going to test display, after checking connection ]

For the LCD screen (Display Panel) side of display cable connection,
remove ALL power, then,

http://www.insidemylaptop.com/replace-broken-screen-dell-inspiron-1564-laptop/

,disassemble down to Step 7. This way you can lean the screen out, and check the connection.
Display Panel connection physically checked reinstall power, turn on, check display.

IF there is obvious visual signs of damage to the sheath of the Display Cable, there may also be damage to the tiny wires inside.
(Stretched/Broken)

A continuity check with a multimeter is warranted.
If the Display Cable's sheath does Not show obvious signs of damage, it is still best to perform a continuity check, so you can Positively rule out the Display Cable as the problem.
Suggest go to a local 'Mom and Pop' computer store, and for a coupla' bucks have them check it.

Or replace it.

Display cable checks out 5by? (OK)
Go on.

Screen Inverter:
The next item to check is the screen Inverter, IF a screen Inverter is used.
90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.
One example of an Inspiron screen Inverter,

http://www.ebay.com/itm/New-Genuine-Dell-Inspiron-1545-Series-Lcd-Inverter-Board-15-6-H251M-0H251M-/300756244730?pt=US_Laptop_Screens_LCD_Panels&hash=item46067818fa

Yes. It's an Inspiron 1545 screen Inverter. Couldn't find a listing for an Inspiron 1564 screen Inverter. Means to me that most of the 1564's use LED backlighting, or everyone is switching to an LCD screen that uses LED backlighting.

Display Panel:
If the screen Inverter checks out, the problem is the Display Panel.
(LCD screen)
IF there is No screen Inverter used, the problem is the Display Panel.

I'm willing to bet you have a loose Display Cable connection, or damage to the Display Cable.

For additional questions please post in a Comment.

[ For the areas you are going in no ESD wrist strap is needed.
It IS however, always a good practice to wear one, and have it's alligator clip attached to a good ground source.

Electro Static Discharge.
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer. (Laptop or Desktop)
Doubtful that you will see it, or feel it. Poof! Your computer is fried.

An ESD wrist strap relieves your body of Static. You CANNOT just touch a metal frame of the laptop to relieve your body of Static, like you can a desktop computer.

Average cost is around $3 to $6. One example,

http://www.radioshack.com/product/index.jsp?productId=2103245

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. I do not feel an anti-static mat is warranted.
You can also set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or use a large metal knickknack (Unpainted ]

8 Beep Codes means its a Display failure. It could be a problem with the Motherboard or the LCD display itself.

Turn off the system. Press and hold down the 'D' key and press the power button once, do not release the D key you should see a set of colors on your screen.

If you do and the colors are fine then there is nothing wrong with the LCD display and the problem lies in the Graphics controller on the Motherboard.

Please call Dell Technical Support for appropriate part replacement.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Meaning the graphics chipset is OK.

Problem lies with the Video Cable, or Display Assembly.
(Dell: Display Panel Cable = Video cable)

The Display Assembly is the;
1) Display Bezel: Plastic thin frame in front of the LCD screen.

2) LCD screen (Dell = Display Panel)

3) Screen Frame: The thin metal frame which surrounds the LCD screen layers, and also holds them in place. (Resembles a picture frame, and can be disassembled)

4) Camera (If applicable)

5) Screen Inverter: (Dell = Display Inverter)

The Display Panel Cable (Video Cable) is a thin flat ribbon cable.
One end connects to the motherboard, the cable then goes up by the left Hinge, and the opposite end connects to the back of the LCD screen, in the Display Assembly.

1) A connection may be loose. One end of the video cable may be loose, to it's connector.
BOTH the connection on the motherboard, AND the connection at the back of the LCD screen, need to be checked.

This means partial disassembly of the laptop body, to check the motherboard connection. It is under the Keyboard.
ALL power removed from laptop, AC adapter (Charger), and Battery, the Center Control Cover needs to be removed next, then the Keyboard,

http://support.dell.com/support/edocs/systems/ins1545/en/SM/keyboard.htm#wp1179911

Also look at the condition of the sheath, of the video cable. If there looks to be apparent damage to the sheath, the tiny thin wires inside may also be damaged. (Stretched/Broken)

Checking the connection of the video cable at the LCD screen, requires opening the Display Assembly.
This requires removing the Display Assembly first,

http://support.dell.com/support/edocs/systems/ins1545/en/SM/display.htm#wp1109848

Both connections check out? Prove to be tight? (If you open the Display Assembly, and the video cable falls off, it wasn't tight)

I would then suggest performing a continuity check of the video cable.
Check each wire in the video cable. (Multimeter set to Ohm's, see if electricity passes through the wires. Continuity)

If the video cable proves to be good, then the screen Inverter is next.

An LCD screen cannot produce light by itself. (Or enough light)
It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.
The Dell Inspiron 1545 Notebook PC uses a CCFL as a Backlight.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
{ Example: 2mm Wide and 334mm Long. That is approximately a little thicker than 1/16th of a inch, (.078), and a little longer than 13 inches }

A screen Inverter converts the power (Electricity) from the laptop, for the Backlight, and LCD screen.

90 PERCENT OF THE TIME the fault is the Inverter.

Fortunately it is also the cheaper of the parts, when compared to an LCD screen, and is easier to access.

It is behind the Display Bezel, and mounted at the bottom of the LCD screen frame.

[ In the Display Assembly link above scroll down to the subheading -
Display Bezel.
In the first photo under the subheading, the screen Inverter is shown at the bottom, of the LCD screen.

This example shows it in more detail,

http://www.batterysupport.com/dell-inspiron-1545-inverter-p-206027.html

To test a screen Inverter you need a sensitive multimeter. This = $$$$
(Or you can use a good Inverter to test)
Barring that the two examples above are not feasible, the alternative is to buy, and replace the screen Inverter.

A) Video Cable checks out it's on to the screen Inverter.
B) Replace screen Inverter does not fix the problem, the problem is a bad LCD screen.

I'm betting on a loose connection of the video cable, at the back of the LCD screen. Just my thoughts.

Post back in a Comment, (Or Comments), as to your findings.

8 beeps indicates a video card problem. Do you see where your monitor plugs in? Is it a seperate card and is that card seated well or is the cable coming from that card plugged in where it needs to go?

You just need a HDMI cable to go from the laptop to the TV. It is refered to as a patch cable. You then go into the TV menu and set it to component or in some cases it will say computer. The VGA on the TV just allows both style interfaces to be connected.

1. remove all ext peripherals
2. remove battery
3. check first the ac adapter if it has led on (make sure ac adapter is not connected to the laptop)
4. try any other wall socket check if ac adapter will led stay on
5. if ac adapter stayed on then connect to laptop (without the batter)
6. after connecting the ac adapter to laptop check if the ac adapter led turned off, if yes then check ac adapter laptop pin on the side if is loose or damage.
7. if ac adapter stayed on after connecting to laptop press now the power button on the laptop just once. check if the power led on laptop will turn on (check if power led stays on or it blinks amber)
8. if it blinks amber then remove all CRUs such as dvd drive, memory, hard drive and wireless cards. put them back one at a time. make sure you turn off laptop when putting removed hardware. this will check and isolate which causing the power led to blink.
9. if the power led stays on then turn it off again then wait a couple of seconds then press and hold on Fn key then press power button. wait for about 5 minutes while the power led is steady on, until you hear beeps once you hear beeps it means that LCD has problems. try then connecting laptop to an external monitor if it shows display there. press on Fn + F8 to toggle the display from LCD laptop to the ext monitor. if no display replace the motherboard. if it has display replace LCD.
