Re: No Signal from Satellite C50D-A-139 HDMI out port

Hi
I have connected toshiba Satellite C50D-A-139 ( windows 7) via HDMI port ( using hdmi cable) to tv plasma, but on TV screen appears only "there is no signal".
I am sure that HDMI cable works good, becasuse it works with Playstation 3 correctly. I have tried to click "winows button + p" "fn button + F4", but there is no result. nothing happend.
I have also clicked right "mouse button" and choose "screen resolution" but there is also only one screen ( laptop screen) to choose. I tried to click "detect" but nothing happend.
Please, give me some advice...

I have downloaded all drivers from "slim drivers free". Program scanned my computers and said that "all updates have been installed". I have also downloaded "Hw set up" from Toshiba website. That utility is directly for my laptop.
And now,when I have opened "HW set up", I've chosen icon "display", then - appears dispatch like this: " this bookmark purpose is to choose inside display or outside screener during activating/starting computer".
Then i have chosen "outside display device" - Tv and HDMI. After that, if I restart my laptop, signal is transmitted to my tv and my laptop display turns black. But only video signal is transmitted to Tv, Audio is still coming from notebook. After that I've return to previous settings.
I have also downoladed "Toshiba Satellite A300D HDMI Control Manager Driver 2.0.0.1", I have installed it but it seems that program doesn't work at all.
About FN keys : When for example I click "FN+f5"- touchpad switchs off, when I click "FN+F9/F10, volume goes up or down. But when I click "FN+F4" computer "Thinks" for a while, but nothing is happening
As you can see, I have enabled right HDMI port. Furthermore if I disconnect HDMI Cable from notebook and connect it to my PS3 it automaticly works just fine.
In past I have been connecting hp pavillon (windows vista) to the same tv, and I haven't got any problems.

Toshiba 32C120U "no video signal" from my Mac Mini using HDMI to HDMI.

My Toshiba 32" 32C120U is not getting video signal from my Mac Mini. I bought the Mini for my son and this is his TV. I have hooked up the Mini to my older 22" Toshiba and my 56" Samsung with the same HDMI cable and it works great on both. What the heck is wrong with my son's 32" Toshiba? I did update the firmware on the TV and the Mac Mini has been completely updated as well.
I have also tried both HDMI 1 and HDMI 2 ports with his Xbox with success, so both ports work. I have also tried both ports with the Mac Mini and there is "no video signal" on both ports. I noticed that when I hooked up the Mini to the other TVs it automatically selects the best video setting, so there is obviously some communication that happens between the Mini and TV, but that is not happening with my son's TV.
Any suggestions would be greatly appreciated.
Thanks in advance,
John

I solved my issue . . . returned the Toshiba for an Insignia . . works great.

Satellite Pro C650-139 - Faulty USB ports

Bought a C650-139 about 3 weeks ago and after 5 days the USB ports started to work intermittantly and then stopped altogether.
Did a system restore and even tried booting with a linux live cd but the machine would not recognise anything plugged into either port.
Contacted the dealer and they got me a shiny new replacement but now it has gone the same way :(
I only have 2 Kingston USB memory sticks and a USB mouse that I've used in these laptops. The devices work fine in other laptops and PCs.
Windows Device manager shows the USB root hubs installed and if I uninstall them then the OS redetects and reinstalls them.
Anyone else had this problem with this model?

I don't have this notebook model but it must be really annoying when something like this happen.
I agree with Jeka. Bring notebook back to your local dealer and exchange it for other notebook model.
Series C must be new one and I think you should take new A series, for instance A660. I saw it last week and I must say it is really nice notebook.

Anyway to get a 1080p signal from fios?

A couple of weeks ago, I purchased a 32 Inch Sony Bravia 720p but yet 1080p compatible HDTV. I know my TV is capable of receiving 1080p signals as most HDTV’s are in the modern era. However, Fios via the HD DVR only broadcast up to a 1080I signal. My question is this, is there anyway to get a 1080p signal from Fios or will 1080I have to be settled for? What I mean is under video options on the set top box the options are 480I, 480P, 720P and 1080I there is no 1080P option.

I’m sort of glad I didn’t opt for a 1080p tv then as in my case it probably would have been a waste, aside from playing BLU ray disk/HD video games. I’m someone who mostly watches their tv and occasional does other things with it (see above.)
All channels are already distributed in compressed format (typically MPEG-2). Some cable providers pass the local HD channels as they receive them, but virtually all apply additional compression on the cable HD channels (i.e. they re-compress). Verizon FiOS is the only major provider does not recompress any of its HD channels to save bandwidth. FiOS does recompress a few [mostly premium] channels distributed in MPEG4 format, but only to redistribute them in MPEG2 for those without MPEG4-capable receivers.
Not all content providers allocate and equal bitrate to their HD channels. Most channels are distributed via rented capacity on satellite, and that costs serious money, especially for content providers that supply mutiple HD channels. More budget consious content providers may use lower bitrates, either to minimize satellite carriage costs and/or make their channels more enticing to cable providers that face severe bandwidth constraints. If a particular cable provider is constrained for bandwidth, they may be willing to add a $10,000 in time and equipment to recompress TNTHD -- a channel many demand -- but they may not be as willing to do the same thing for a lesser watched channel like HGTV. Cable channels like ESPN, TNT, USA, SciFi, Hdnet, MHD, and CNBC all distribute their channels at fairly high bitrates, while cable channels like HGTV, Discovery Channel, Animal Planet, and the Science Channel are distributed with significantly lower bitrates.
Local broadcasters (ex: ABC/FOX/CBS/NBC) all have 19.4Mbps available to work with, but that must be split between the main HD feed, any SD subchannels for traffic/weather/etc, and a limited amount of PSIP guide data. Some broadcast networks also sell a portion of their bandwidth to other companies for commercial datacast purposes. These days, it's very rare to find a network affiliate that uses anything close to 19.4Mbps. Most independently owned NBC and CBS affiliates dedicate just 12-14Mbps to their HD feed, with the rest used for weather / traffic / news subchannels. A 12-14Mbps feed is generally sufficient to provide a high-quality picture on 1080p24 sourced content like movies and episodic series -- albeit with some added blurring on motion -- but is often inadequate to provide a high-quality picture on native 1080i60 video with lots of movement, such as sports. Today, the best network picture is typically found on CBS owned-and-operated affiliates, as they all devote at least ~16.0Mbps to their HD feeds.
Less bandwith for the HD feed translates into higher compression. Generally, the first thing compression equipment does is is filter [out] shadow detail. This includes fine details that you might see in faces, hair, and clothes. After that, compression equipment will reduce the amount of motion information in the picture signal, resulting in more blurring. Compression may also reduce the color gradations in certain parts of the image. When all this is inadequate for a certain scene to achieve the desired bitrate set by the cable company or broadcaster, you'll start to see more obvious defects like blocking and/or stutter (dropped frames). This is most common in motion scenes, which require significantly more bandwidth than static scenes.
In an ideal world, Verizon FiOS would obtain full-bandwidth 19.4Mbps feeds from each ABC/CBS/NBC affiliate, but that just isn't an option without buying thousands of dollars in new equipment for each affiliate. Most local networks use equipment that allows them to output their commercially-integrated channel at one bitrate and one bitrate only, so Verizon is stuck with the same feed used OTA. Perhaps one day, when Verizon makes the move to MPEG4, it will offer to buy new new encoders for CBS and NBC affiliates in major markets, to provide the absolutely best picture available [anywhere] on those channels. We can dream.

Signal from GPS toolkit

Hi, I am working on the example module "niGPS Write Waveform To File". I use the default settings to generate the baseband signal.
Now I am tring to simulate if there is a GPS signal in it. I read signal from the file into matlab, and try to acquire a GPS satellite, but cannot find it.
I checked again and again, do not know what's wrong with it.

Hello usami,
This is most likely due to incorrectly reading the data from the binary file. The file is a 1D Array of I16s that is interleaved I and Q data with a 512 byte header.
The header consists of 8 bytes of version information for the version of GPS toolkit used to generate the file, 16 bytes for the IQ rate and peak power of the waveform and 488 bytes of that are used for padding. Without accounting for this header data you will be unable to accurately reproduce the waveform that follows.
When using the GPS toolkit and an RF Upconverter in LabVIEW you would then upconvert and generate the resulting waveform using the niGPS Streaming From File VI.
Exactly how are you using Matlab to simulate the GPS signal in the file. How are you trying to acquire a GPS satellite?

Dan King

How to change HDMI port settings from output to input to accept signals from cable/satellite box?

I have a new dv8t Entertainment PC with the HP Integrated HDTVHybrid Tuner. The instruction manual provides 2 ways to connect the laptop to a cable/satellite box: (1) coax/rf; or (2) HDMI. The coax is a no-brainer; got it up and running in 10 minutes. However, I am unable to get it to work connecting the HDMI cable, as the HDMI port on the laptop appears to be stuck in output mode. How do I change the configuration of the HDMI port to "input" so that it can accept signals from my cable box?

Thank you Grant for the quick response. Well, it seems I don't know what I'm doing.
So, Mac Pro doesn't have any video INPUTS just Outputs. CHECK.
That is correct I have a six-input-port-selector with one input (SWITCH C2G). CHECK.
What I want is to be able to toggle through the inputs from the HDMI Switch C2G. That way I can use all my devices (Mac Pro, Xbox, PS3, Cable Box) with these monitors.
Since the Switch C2G only has one OUTPUT Slot, I'm thinking I just need to connect the monitors to the Switch C2G Output slot by using a 2 to 1 HDMI Adapter, but wouldn't I lose the true potential of these monitors by not connecting them directly to the Mac Pro?
Currently, I have the monitors hooked up with Thunderbolt/Mini Display Adapters to the Mac. So I guess I would just have to run just one HDMI with Thunderbolt/Mini Display from the Mac to the Switch C2G, and connect the other devices to the Switch as well.
Jeez. Am I right?
What If I get an HDMI Switch with 2 Outputs instead of getting the 2 to 1 HDMI Adapter or perhaps a 4 to 2 Adapter. Heck. I'm not sure what to do here.
I would really appreciate anyones help.
Thank you.

Satellite C50D-A-13G affects Wi-Fi connection of other devices

Hi all, first post and a problem, like most I guess !!
Bought my first W8 Laptop Tosh Satellite C50D-A-13G
The wifi is driving me mad
When it does connect to my BT wifi,, all other devises in the house loss their wifi connection,,
Seams this new laptop , "hog's" the connection,
Only way to get out of it, is to pull the power from the BT box,, and wait 5 mins !!
I am guessing its a window 8 setting somewhere,, but regret I am somewhat of a IT dummy !!
Any help would be appreciated please,,
TIA
Tim

To be honest you are the first who reported something like that in this forum community.
From my point of few there must be a configuration problem with your WLan router.
I would recommend you to reset the settings and to reconfigure the router again.
Check also the router user manual and maybe support website of router manufacturer page for possible issues and workarounds.
Fact is that if DHCP is enabled in your router settings, the notebook and all other devices will get the IP address automatically from an IP address pool. This should not affect other devices since each device would get an separate IP address.
I would also recommend you to check in router settings the different WLan standards like 802.11 A, B, G or N and different frequency modes 2.4Ghz and 5Ghz and channels.

Satellite L70-A-139 - SSD upgrade

Hello,
I have a Satellite L70-A-139, and I want to upgrade my HDD to a SSD. I already opend the back to see, and there is a label that saids 'only 7mm'
The ssd that I want to buy is a SSD 840 EVO 250Gb.
But that one is 6.8mm in height, will it give installation problems?
Thank you

I don't think so. Carefully remove two screws that secure HDD assembly and disconnect the HDD assembly from the connector on the system board.
When the HDD is out place it on flat surface and remove HDD bracket.
To build in new SSD should not be complicated.
I hope you have created recovery media. If not do it. this recovery media you can use to install original Windows version that you got with your machine.

Wireless signal from iMac to TV?

I have a new 20" iMac G5 isight on the way and have a question. Has anyone tried to hook up the iMac (or other mac) wireless to your TV. There is products like this www.amazon.co.uk/exec/obidos/ASIN/B000068TYR
ref=erra_acc_dp1/026-6032989-4654855 that will send a signal from your antenna to your TV wirelessly. I thought mabye in combination with a TV tuner like EZ there would be a way to get the signal from the mac to the TV. That way I dont have to drill a cabel-hole in my livingroom floor down to my office to enjoy FrontRow on my TV. Or is there any other solutions/suggestions?
(And i dont think there will be an Airport Express A/V launched next week... though I wish!)

You should be able to connect your ATV directly to your iMac using Internet sharing, but you can't use the same NIC that the iMac is using for its connection. If your iMac is connected to your router by wi-fi, you can share the Ethernet port with the ATV. If your iMac is connected to your router by Ethernet cable, you can share your iMac's AirPort with the ATV.

Getting Started with Labview.pdf ‏901 KB

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

"Example on reading combined signals from a serial port and separating them for display purposes". I am a beginner in Labview and would appreciate if anyone help with that

I am working on a wireless vital sign monitor. I have 3 signals; heart rate and temperature. I filter and amplify the signals before converting them into digital form. I then pass them via MAX232 before passing them to RS232 serial cable.
I am therefore working on a program to receive the combined signal and separate them.
I have come across serial read and write examples on ni.com but am looking for one where I can actually separate combined signals and display them separately.

Reading the serial port will give you a string. How you divide the channels depends on how the data was formatted before it was sent over the serial channel.
If you are designing the instrument, as it seems from your query, then you can set up any form you wish. If your data is always floating point numeric, you could use space or tab characters to separate data words. You could use and XML format. If the instrument is provided by a vendor, contact them for the protocol.
If tabs are used between words and returns between sets of readings, the resutlant string can be interpretted by the Spreadsheet String to Array function in LV.
Things to avoid are characters often used by serial communications systems as control characters. Carraige returns are
often used as command terminators by serial protocols, but may also be used by the port.

How to compare signals from two different .tdms files?

i'm developing a lie detection system in labview.so inorder for that i need to compare the threshold physiological signals from the .tdms file with the signals i acquire continuelsy from the subject for each question asked.i use respiration monitor and heart beat monitor together with the sensorDAQ to acuire the physiological signals.so which are the function i should make use of?i have the following toolkits
1. advanced signal processing toolkit
2. adaptive filter toolkit
3. digital filter design toolkit
4. biomedical toolkit
please give me advise on this.
thank you.
Solved!
Go to Solution.

Lie detector systems (polygraphs) generally work by looking at the physiological responses to the own subjects baseline, and do this in real-time. You could use a file that represents the stored "baseline" for the subject, but the overall environment, circumstances, general state of the subject, etc. may not be similar enough to easily see subtle changes.
From the stored file, you might determine a set of parameters or thresholds that indicate "normal, relaxed" for each signal. You could read the file into your LabVIEW program, process each channel, and save these parameters. Then when you have the new data, you can read the new data file in and process it in a similar way and then determine whether the parameters are outside the limits that you established for a "lie".
