Question about Toshiba Tecra A4 Notebook

Display problems with 2 yr old Tecra

HI - I have two problems, don't know whether they are related. First, similar to others I sometimes find that the laptop screen gets vertical multicolerd lines; theyusually resolve after 30-60 secs, but come back repeatedly. Other times I have something best described as "northern lights' with the normal display turning into vague colored shapes moving up and down. Usually resolves temporarilty too. Sometimes this is frequent, other times I can go a week or more without it.

Second, I need to be able to hook up an external monitor, so I purchased a second hand Dell flatscreen. One i got the hang of the Display properties settings it was fine for a few months. Then it started refusing to display even with power on etc. I fixed it once with the Fn toggle settings. The last time it was on it suddenly went blank and haven't been able to get it back.despite trying all of the above in various orders. THe flat screen shows power on, seems to try to 'glow' green/yellowish at the edges but no cigar. It also occasionally flashes something about 'Analog input' and 'video mode' too quickly for me to accurately catch.

I'd be very grateful for any help with either or both of these -

KW, glasgow

    thanks, it sounds plausible. I'll try to turn it off between uses more often. KW

  • kwglasgow May 13, 2008

    Thanks much, I'll try these. KW

  • kwglasgow May 13, 2008

    Yes, I should have mentioned I connected the monitor to another laptop and all was well, so it doesn't seem to be the screen. KW

  • kwglasgow May 13, 2008

    No magnets in area (unless there's something else that functions as one.)

    Its a Tecra A4, single core processor,750mg ram, 14" screen, etc. I sthere anything in particular you might want to know...

    Thanks, this makes sense. Does one need to return it to manufacturer for repair or is this a job a more general pc repair shop might be able to identify and do?

  • kwglasgow May 13, 2008

    It's a T1300. Thanks for the warning. Would the VGA problem also cause the external monitor issues?

  • kwglasgow May 13, 2008

    Thanks - will need a bit of time to deal with drivers as I don't know/trust myself enough to do it on my own and need to find someone who can help. kw

Try to connect the monitor to check if the display is working, if it is working then the problem is with the laptop or if not then the flat screen is defective get it serviced........

    first thing i will advised you is check first any possible contact on the object that has a magnetic or a magnet into it..

    I recommends turning off the display and unplugging it from a power source for 48 hours. This may correct the problem on many TFTs and LCDs.

    It happens when the image or part of the image an LCD displays doesn’t change for a long period of time.

    To avoid future burn-in, use a sleep mode to darken the monitor during periods of inactivity. A screen saver or a TV channel without a logo continuously present on the screen can also prevent burn-in from unchanging image elements.

    Thank you

    the second may be due to the connections inside ..............if that
    is found and soltered then it will be overcomed............and colour
    dullness and blank screen may also because of using for many
    hours..............

    Ok, this seems like your laptops vga is failing / overheating. Try reinstalling the drivers and re-enableing the 2nd output on the control panel - display properties.

  • Ekse May 13, 2008

    Honestly I'd recommend you go with my support since I've previous experience in these problems also worked in a pc repair shop.

    So try that and report back.

  • Ekse May 13, 2008

    Well its most likely that your vga board is about to reach the end of its life. They don't last long since they get very hot inside laptops, my acers vga died 2 times becouse of overheating with similiar problems.

    If the vga board is buildin into the mainboard then the whole mainboard would need to be replaced.

    So there might not be a easy fix / cheap fix for this.

  • Ekse May 13, 2008

    Also my email is nikoht@gmail.com feel free to email me.


  • Ekse May 13, 2008

    Whats the Tecra A4 Model number?



    Toshiba Tecra A4-S211 for examble

  • Ekse May 13, 2008

    Well most pc repair shops / pc shops not like wallmart or bestbuy but real repair shops they can find the problem and order + replace the parts needed. But have you tryed the drivers and things? Also cleaning the laptop from dust to improve the airflow might help a little. but ofcourse it wont reverse any damage already happened in the chipset.

  • Ekse May 13, 2008

    Yes the same vga board runs both video outputs.

  • Ekse May 13, 2008

    the T1300 is a processor :-P

    Can you check the model number on the bottom? I might be able to find out how much the repairs would cost and is the vga board replaceable or build in.

  • Ekse May 13, 2008

    Also mate, dont forget to accept my solution :-) the button should be right down here.

  • Ekse May 13, 2008

    Hey I can do it remotely if your intrested! please email me right away!!



    nikoht@gmail.com we can do it right now. Aslo remember to accept my solution.

  • Ekse May 13, 2008

    I ment also :-) not aslo

Hi

Sometimes the resolution changes to an unusual setting when an external monitor is attached. make the LCD screen your main monitor and change the resolution to 1024x768 or 600x800 whichever is best.

Hi! no sound from toshiba tecra notebook


Check the volume knob usually along the side or front first.

If you're sure its turned up, then i would install sound drivers from http://pcsupport.toshiba.com and let us know if that doesn't fix it.

Include what model tecra if you have further questions please.

Vertical Dotted Lines on my Toshiba Tecra


Hello,

My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue related to vertical line across the screen . I would like to provide my suggestions on the issue.
I hope that this should work for you and will resolve the issue.

Well, this issue could happen due to below causes:

1. corrupted Display Adapter drivers in PC
2. If the OS gets corrupted.
3. If there is an issue with BIOS


To isolate the issue, I recommend you to try below solutions.

1. Try to work on System Restore if you are using Windows XP or Vista. Sometimes this could resolve the issue.

2.  Then try to load the PC in to BIOS, I mean get into BIOS screen and check if there is any vertical line across the BIOS screen. if you do not see such line while in BIOS, then it confirms that this is an issue with Software related and not  a Hardware related.

3. If  found that this is an issue with Software, then load the pc in normal Mode and then try to uninstall and reinstall the Display Adapter Drivers in your PC. This should resolve the issue. If the issue still persists then go ahead with Reinstall of Operating system. This is only ultimate solution for the issue.

4. If  found issue with Hardware related, I mean if you see a vertical line in BIOS screen, try to Flash the BIOS once. It means Update the BIOS. OR load the Latest BIOS that is available for your PC model.

For your convenience, I made alot of search and found a link for BIOS update.

Link is :

http://www.csd.toshiba.com/cgi-bin/tais/su/su_sc_modSel.jsp?BV_SessionID=@@@@1152030123.1193528933@@@@&BV_EngineID=ccchaddmfmhhlehcgfkceghdgngdgnn.0

Once if you open the link, please select the correct Product type as : "Portables" and then Family as " Tecra" and then select correct model number of your PC and click Ok.

This opens a new web page, try to locate the updated BIOS driver. If you find there is new updated version of BIOS, then please download and install it. This should resolve the issue.

However, if the issue still persists then it confirms that this is an issue with Hardware Malfunction of PC. Then you need to contact Manufacturer on thes issue further.

This should resolve the issue for you.

 If you need any further assistance on the issue, you can mail me at thumuvikram@rediffmail.com . I'll be glad to help you.

Bye.
