Sorry if this has already been posted, but i need a answer quick...
When ever i first start up my pc, turn on the screen... its a blank white screen.. .i've actually timed it it takes about 15 minutes, if you press off and then back on, the picture comes on just fine. If i restart its fine. Just at startup is when it shows the blank screen.... i hope this can be repaired with not such a big cost

I have exactly the same issue - its as if the monitor needs to warm up or charge capacitors to get to a proper operating status. I tried a different monitor from start-up and it worls just fine. If I turn the machine off when its been on for some time and turn it back on the monitor starts up fine. Its just when it hasn't been used for some hours.I have exactly the same issue - its as if the monitor needs to warm up or charge capacitors to get to a proper operating status.

I have a Xerox XA7-19i. It has the same problem as described by many
others - intermittent fault with the display that manifests as a white
screen when the monitor is first switched on. After a few trys of
switching on and off, the monitor works fine until left off for a few
hours. Recently, the problem deteriorated to no light from the panel,
and a flashing blue power light.
I HAVE SUCCESSFULLY REPAIRED MY MONITOR:
I opened up my monitor and removed the power supply board. I de-soldered every electrolytic capacitor, and replaced them with new capacitors of the same uF and voltage rating. I put the monitor back together again and switched it on - it worked perfectly!
Yes
- these monitors have been built using sub-standard / under-rated
electrolytic capacitors. After two years of use, the power supply board
was unable to supply enough power to the logic board and backlight,
causing the above-mentioned problems.
The repair cost me ~ GBP
15 (USD $30). It is not a difficult fix, but one only to be attempted
if you have electronics knowledge. Careful, kids! you'd be playing with
the power supply of a mains AC electronic device. That stuff can kill.
But
- I saved myself (and the environment) from having to throw out a
monitor and buy a new one. If you have a faulty xerox monitor and are
getting no love from Xerox customer support, find an electronics geek
and ask them to replace the electrolytic capacitors on the power supply
board. (but be careful to get the right kind of capacitors, and to get
the capacitor polarity correct. If you have any doubt as to you ability
to do this, don't bother trying!).

Teresa,
leave the Toshiba powered on for a couple of hours with the black screen
why you ask
If it is running Windows it might have downloaded an update
in the background when it was online to the internet without you being aware of it,
Then when you turn off your computer and restart it or power it up.
Windows tries to install the downloaded window's upgrade and the maker's of Windows o/s in their infinite wisdom thought it would be great to display a blank screen instead of the words windows update installing please wait.
Eventually you might be lucky and see a message after 30 minutes to 1 hour of waiting with a blank screen that Windows is updating its operating system
Quick answer - not specifically to change font size, but to change whole screen size
The whole screen size can be magnified (zoom in) by simultaneously pressing CNTRL + ; the reverse operation (zoom out - what you want I think) is performed by CNTRL - (press cntl and + keys simultaneously)
Or change (increase) the resolution of the screen by right clicking a blank a blank area of the desktop and selecting 'screen resolution' in Windows 7 or in XP one the tabs similarly labeled, and increasing resolution if not at max already.
Try starting the PC in safe mode (press F8 as it starts) and then restore your PC to a date before you installed the updates.If that fails you must use your windows 7 disk to repair the system or just install it again.....
Here and here are a couple of links from HP that may help. And here's a great article for troubleshooting startup problems in general. Also helpful may be links at this site.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread. If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!
insert os boot disk if xp choose install first but after it searches disk for previous widows installs choose your already installed windows and select r for repair,do not select repair at first screen or it will load a dos utillity that will be harder to accomplish repair.if vista, after boot disk loads choose repair vista in lower left corner then on next screen choose repair startup option....hope this helps you
The video resolution and/or frequency that's set in windows is not supported by the monitor you have plugged in. Restart the PC in VGA mode (hit F8 after the BIOS messages but before any Windows messages) and change the video settings to something basic, such as 800 x 600 @ 60 Hz. Then restart the machine normally.
It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard?
