hello guys!
please help me!
i have HP71 monitor 17" color model D8901A chasis CMC4217.
it was all running ok. suddenly there was a very bright thin vertical white line in the monitor.
i watched closely and found as if the picture was squezed by 1-2mm SIZE.into a thin vertical line.
after few seconds the mionitor went dead and tik tik sound is continuously coming(may be from the flyback). i changed the flyback transistor but nothing happened.
please check what to check/replace next?
please tell me the precise number e.g(R540 OR C217 etc) for checking and replacement.
waiting for your reply
take care
If you have a service manual I could assist you with this repair. Tube type monitors these days you can get used even for less the 50 bucks. Is this monitor worth the time and trouble?
Thanks for the reply!
i am living in a country where monitors are not so cheap! so i am ready to go for the repair!
i shall be highly grateful if you could please help me in this regard.
i dont have the service manual. i have the user manual but i think this will not serve the purpose.
if you have any please send a copy. or devise any way out.
please reply.

Service manuals for computer monitors are basically non-existant. You'll have to fly by the seat of your pants on this one.
Yeppers, these manuals are rare. I have found out though on this set if you get a tick sound the flyback is bad and the part is no longer available. Good luck
thanks!
is that so rare!!!!!!
ok
what next?
should i throw my monitor in the trash?
can i replace the flyback from any other monitor? what are the precautions for swapping the flyback with other one?
will 14" monitor flyback will work with 17" flyback?
thanks
The problem is that every flyback is built differantly. All of the pins do not line up and do the same thing.
