Sony Trinitron 17" Monitor - No Image, Out of Range, Power LED lit though - HELP!

[Mark Brooker]

Hello, I havent got a clue about fixing monitors. I am interested in knowing
what the problem could be, whether it would be worth being fixed.

Here's what happened:
I was poking my graphics card about while my pc was turned on - because i
have bought a dodgy ATi that causes major gliches in games. By pressing on
it i can remove theses glitches. Anyway, i was pressing on it as usual and
suddenly i got a blank screen with an "Out of Range" message box in the
centre. Then it shut down.
I managed to restart it with no problems, everything was runing normally, i
then fiddled with the card again and this time, no message box appeared it
just shut down.
Now the monitor's light turns green when power is provided, but there's no
picture at all.

The Monitor's max refresh is 60Hz, but i tried running it at 70 for a week,
and it worked fine. I cant remember if when the incident occured i was
running at 70Hz still, as i'd been changing settings all over the place
trying to sort out my graphics problems.
The resolution it was in was 1280 x 960, and i was playing Myst: Uru. The
refresh was noticeable.

I have checked the cables, the pins are perfect, none missing, none bent.
Also swapped power cables, and tried wiggling the ends incase of poor
contacts.

I have left the monitor off for a few days and tried plugging it back into a
different system, with video set at 60Hz refresh. Nothing.

I can hear a quiet high pitched sound from the back, getting louder and then
dying, repeating itself after turning the monitor on for 5 secs.

Any ideas? If your interested in buying this off me also, let me know. I
live in the East Midlands, England.

thanks
Mark

Something is shorted, probably a diode or transistor in the scan circuitry.
Good luck getting someone to buy it, I have one sitting in my garage with a
similar problem I haven't been able to give away for free so far, I'm sure I
could fix it but it's hardly worth it, used monitors have very low resale
value.

The video card may not properly be loading the video driver. Is there
a display during the initial PC boot? (POST) If not, turn off the
computer, remove the ATI card, clean contacts, reinstall card, turn on
and boot. Also look for a defect in the VGA cord from the monitor.
Wiggle the plug.

In BIOS look for a secondary video port on the Motherboard, disable
it. Set "AGP" or "PCI" first VGA priority according to the slot type
of the card. Try booting while continually pressing and rebooting
the F5 key to get into "Safe" mode" Does the display appear here?
Unfortunately the ATI card drivers generally don't remember settings
entered while in Safe Mode, and upon normal reboot it may go back into
the unsupported scan rates. If this happens go into "Safe" mode
again, then UNINSTALL the Video card in Device Manager, reboot, then
reinstall the correct drivers, NOT saving previous serttings. Finally
the video card may have had static damage, or has a dry joint, but the
way these things are put together the latter is unlikely.

On another tack, some Soyo boards do have mechanical problems with AGP
video card mounting, also a few Asus boards such as the CUSL2 "forget"
to assign resources to the video card, thus even initial boot doesn't
show. The above procedures should clear that issue. If not go for
broke -- with power removed from the power supply, remove the battery
to reset the Bios, put the battery back in, boot to Bios and set to
"setup" defaults, then reboot.
