How to fix a blank screen?


Dont know anyone who would own a Kyocera Cell Phone these days that would be able to comment about it's workings. Must have enticed you with it's price.
Try charging it with a known working charger.
Remove the battery, Give it three sharp taps on the lower left corner, replace the battery and try powering up again.

I have a whirlpool built in oven. Model RBD275PDQ8. The display (control panel) went blank 2 months ago. I reset the breaker, nothing. Pushed buttons, it just beeps. 3 days later I pushed the upper oven...


it's the control panel behind that touchpad item. and it's not too difficult, just time consuming. My recommend is to grab a service manual online(usually around 20.00) which will provide good step by step,and also parts list.

spares? well, that's a good question. Until you have that part number, and the best way is to eyeball the one that's in side your unit(no offense to the printers, but mistakes can happen with manuals).

then you'll find out what it's like to be truly handy, eh?

Reset bios on toshiba tecra pt831u


I believe your model is Tecra S1 - PT831U. I found htis link and the BIOS version is 2.50. You might need to install things in a certain order, (I know this to be true for DELL laptops)So first some instructions from Toshiba,: "
.....Follow the steps below to procure or view any of the following support-related items for your Toshiba computer:
  • Drivers
  • Utilities
  • BIOS updates
  • Detailed Specifications
  • User's Guides
  • Product Tours
  • Support Bulletins
1. Click Product Support in the navigation bar toward the top of the page of ths website (the Toshiba Support website -- support.toshiba.com).
2. Choose a product Category, Family, and Model from the lists and then click GO.
For example: Portables, Portege, R500-S8199, GO.
A list of Support Bulletins for the selected model will appear, since that tab is selected by default.
3. Click other tabs to see Downloads, Detailed Specs, the User's Guide, a Product Tour, and other content for the selected model.

4. For Downloads and Support Bulletins, you can use the Refine Search By lists to narrow your search to a specific operating system, and/or to a specific technology topic (BIOS, Wi-Fi). A more specific results list will be displayed.
5. Click the title of any item in the lists to view or download it.

That is a memory error. Remove and reseat the memory in your computer. If the error persists and you have more than 1 stick, try each stick separately to find the faulty unit. If you only have one stick, then the memory will need to be replaced.

We just purcased Toshiba 26AV502U, now the screen is blank


Heard back from Toshiba. They said to unplug the TV, wait at least 3 minutes, and then plug it back in. This should allow it to reset itself. Sounded too simple, but after doing just that the tv has worked fine for the last three days! Toshiba noted that if this didn't resolve the problem we should contact them to have a Toshiba Authorized service person come check out the tv. It worked for us, hopefully it'll work for you too. Good Luck

Screen went blank sound ok


Do yo have the remote? Do you have the manual? Manuals are usually available online.
If you are feeding the Toshiba with cable wiring then the problem is with the Toshiba. Maybe something as simple as the wrong input is selected on the remote control. If you are feeding the Toshiba with audio and video cables then the input to the Toshiba would be suspect. Either cabling (the inputs and outputs are plugged in wrong. If you changed anything I would retrace your steps.

Let me know by clicking on 'ask me' and if solved please do the rating. Thanks.

No screen on my toshiba 9100


Hi Alex

I suggest going to Safe Mode and see what happens. You do this by tapping F8 right after the Toshiba splash screen. There should be an Advanced Windows Options menu. Choose Safe mode and wait, if everything appears ok then its probably a driver problem, a reinstallation of those should do the trick, if not, then we might be looking at something a little more critical. Let me know what happens.

Cheers;

Possible bad solder connections in convergence circuit or vertical deflection circuit. This happens in alot of equipment. After warm up, expansion of joint pulls connections loose. Recommend not running like this, could cause component failure.
