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 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!).
Good luck!

blank screen 15.20 min before it work?
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.
