Depends on the available connections on the laptop.

You can use the basic monitor out (usually blue) for picture and an mp3 - rca cable for the sound.

Also a white digital out is sometimes present on laptops which can be also used.

There are many ways but as I said it depends on the laptop options.

But better still is hdmi for both if your laptop has it.

Does toshiba satellite m505-s4940 come with hdmi port

Quoted from CNET review:

"A full-size ExpressCard slot and a memory-card slot are all welcome features, but HDMI has been dropped in the S4940--a plugged-up port is all that remains. "

Hello, my question is regarding a toshiba satellite m505-s4940, after opening it for cleaning the screen is no longer turning on, I checked to see all the cables and plugings were connected andi its still...

New screen? Let's not jump to conclusions. You need to diagnose the problem.

1) I hope you observed Anti-Static Precautions. Did you use an ESD wrist strap, and have it's alligator clip attached to a good ground source?

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out,(Short Circuit), the delicate hardware components inside a computer. (Notebook PC or Desktop PC)

Relieve your body of Static before working on your computer.

With a desktop computer it's easy.
Work on a table, computer unplugged from power, computer case open.
TOUCH an unpainted surface, of the metal frame of the open computer case.
(Should you leave your computer in the middle of working on it, {For any reason}, be SURE to touch the metal frame again upon your return)

With a laptop no such luck. You need to discharge Static from yourself, before disassembling the laptop to clean, and ensure during the cleaning process your body is free from Static electricity.

I connect the alligator clip of my ESD wrist strap, to an unpainted surface, of the metal frame of an open empty desktop computer case.
Alternatively you could touch the metal frame of an empty desktop computer case before starting, and during the process.

A Processor is the most susceptible hardware component to Static shock.
If you removed the Fan Assembly, and the Cooling Tube/Heatsink, you are dealing directly with the Processor.

IF, the Cooling Tube/Heatsink assembly was removed to clean the Heatsink fins, the Processor is exposed.

The Cooling Tube/Heatsink assembly should be removed also, to clean the top of the Processor, and bottom of the Cooling Tube plates, which sit on top of the Processor, and graphics chipset (GPU), and to Properly apply fresh, new Thermal Paste.

If Anti-Static Precautions were not observed, there is a good chance the Processor is fried.

[ It is GOOD insurance, when cleaning a laptop, to go ahead, and replace the thermal paste. Thermal paste dries up over time, and loses it's conductivity properties.

If a Thermal Pad is used, it is a definite good procedure to replace it.
A thermal pad is J-U-N-K.
The pad should be removed, and all traces of it removed also.

A plastic scraper, (Old credit card?), and Q-tips dipped in Isopropyl Alcohol, (Will take quite a few), should be used to clean the top of the Processor, GPU, and the bottom of the two metal plates on the Cooling Tube, which sit on the Processor, and GPU.

Isopropyl Alcohol is EXTREMELY FLAMMABLE.
Use in a Well ventilated area with NO sparks or flames present }

The GPU for the Satellite M505-S4940 Notebook PC, is an Intel GMA 4500M.
On the Cooling Tube the first plate away from the finned Heatsink, is for the Processor. The second plate is for the GPU. I'm looking at the Service Manual right now ]

That said, let's go on.

2) Ram memory module/s ('Stick')
Make sure all ram memory modules are properly seated.

3) Make sure the two cables are plugged into the screen Inverter.

To find out if you have a bad LCD screen, or the problem is the screen Inverter;

A) Laptop OFF, monitor OFF, plug a VGA monitor into the VGA port, (Left side/Rear. Is stated by Toshiba as an RGB output.
This example shows a VGA cable, and a VGA port { Connector}, )

You can use a CRT monitor (Looks like a small TV), or a flat LCD monitor that has a VGA cable.

Monitor cable plugged in, screws tightened, turn the monitor on.
If a CRT model allow it to warm up.
Turn the laptop on.

By default the external monitor (VGA monitor) should automatically show a display.
If not, press, and hold down on the Fn key, and tap on the F5 key.
(Display Toggle-Over key)

Still no? Hold down on the Fn key again, and tap on the F5 key again.

If still no display you have a problem with the graphics chipset, (GPU), on the motherboard. Motherboard replacement.

If there is a display on the external monitor, you have a bad screen Inverter, or a bad LCD screen.

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

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

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

90 PERCENT OF THE TIME the problem is the Inverter.

If a display shows up on the external monitor, I would suggest replacing the screen Inverter.
Cost is very economical, and replacement is easy.

If the Inverter does not repair the problem, then suspect the Backlight, then LCD screen.

For the Satellite M505-S4940 models however, the Backlight is a series of LED lights. No Fluorescent lighting is used.
This means if there is a problem with the Backlight, the entire LCD screen needs to be replaced.

One example of a screen Inverter for a Satellite M505-S4940,

Just to make sure you have it, here is the link to the Service Manual (Free) for the Toshiba Satellite M505 series of Notebook PC's,

Scroll down to the second Satellite heading. The one that begins with Satellite A10.
Go to the 5th line down, and left-click on M505.

This is a PDF file. May take up to 30 seconds after you click, before the first page comes up.

After connecting the external monitor, and performing this part of the diagnoses, post back in a Comment as to your findings.
