Question about Sony Computers & Internet

Open Question

I have a Sony CPD E400P trinitron Monitor, screen became blurred.

I have a Sony CPD E400P Trinitron Monitor, bought in 2001. In 2004 it developed a fault - the screen gradually became more blurred, the blurr coming and going slightly. Sony repaired it for me under guarantee. Now, July 2009, the poor old thing has developed the same fault, but Sony (S. Wales) say they have not repaired one of these CRT monitors for 2 years and say they would charge £95 to look at it plus X for parts. Is the fault recognisable. If it is not in the tube, how might I, having a reasonable experience of electronics (e.g. Ham Radio license, rebuilt an old electron microscope), repair it?

Only if you need the heat from it; flatscreens of the same size use around 1/10 the power of the CRTs. Since businesses could make up the cost of the monitor in less than a year of the power savings, in 2000, it's definitely safe and wise to go flatscreen in 2008.

I used a CRT to heat sandwiches in a place with no microwaves in 1993. Otherwise they're hulking abominations that kill species.

SOURCE: LG 700E monitor gives a blurr vision

open unit, adjust focus pot on flyback, may have 2 focus pots.
do both until satisfied.

If the problem varies with temperature (on time), then you may have a failing flyback.

SOURCE: crt monitor gradually develops a

CRT monitors have three color "guns" in them - Red, Blue, & Green. If one of them is starting to go south you will have a tinge as you describe. To make sure it's the monitor, try connecting a different monitor. If the monitor is the problem, it's not worth fixing. Replace it.
If, after changing the monitor you still have a color tinge, you have a problem with your video device in your PC and you need to have it checked out by a PC Technician.
If you have any additional questions contact me by clicking on the "Add a comment" link located under your problem description on FixYa. Also, if you believe that this information was helpful to you, please return to the FixYa website and rate my response to your question.

Monitor


Are you sure this is a monitor problem? I have a user with a Mac that occasionally has the same symptoms you describe. For me I generally have to shut the computer down and physically unplug the power cord from the computer (not monitor), reattach it and restart. Let us know if that works for you.
