Removing green crt

I couldn't find your instructions on how to remove the crt on the Sony KP57WV600. I remove the fron panel and the circuit card. Is it dangerous and should I hire a repairman? Thank you.

More than likely you don't have to replace the CRT. Go to this blog for instructions for how to fix the most common problems.
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

At the bottom of the page there are comments from users. There are several users that explain how to take off the front panel and where things are located. The model KP57WV600 is different than the pictures in the blog, including the fact that the order of the red, green, and blue adjusters are different.

If you try it and it's not successful and you still want to try to replace the CRT yourself, google KP57WV600 service manual and you can buy it for $9.99 and download it right away.

I wish you well.

I have a 60" 2005 sony wega tv and the picture is


It is possible that there is a fault on the CRT or in the drive circuit in the CRT section.

There is every possibility that the fault can be a dry soldering joint in the CRT section of the TV. So remove panel and make a good soldering on the CRT board, the main board and the connectors.
This must solve the fault provided that the CRT is not faulty.

Speaker panel


The panel just pulls forward to expose the inner CRT cover. If youy have the faint blue lines that appear especially when there is an absence of video on the screen, the adjusting of the blue CRT control is a VERY temporary fix. It indicates the blue CRT is shorting out internally and that the red and green might not be too far behind. The bad news is 2 of the 3 CRT's are no longer available.

Go to this site, follow the instructions, and it may fix your problems. I did, and my tv is better than ever!

I was having this problem with blue. I was able to fix it, and now my tv works again. For those having trouble removing a different front panel, here is what I found on mine -

I own a KP57WV600. Removing the front panel is a little trickier on this model. You remove the 6-8 screws on each side behind the two speakers. You will access these from the lower rear/sides of the TV. Remove the small 2ft plastic pieces. Now from the front of the machine grab the entire lower piece (speaker covers & power/volume/chanel buttons) from the bottom and pull down and towards yourself. There are 4 slots that this piece fits into. I had to take off the lower back panel to see why it wouldn't come out. Don't pull to far because this lower front piece is connected to wires. I'd say you have about a foot of play. Now you can remove the fiber board panel and access the blue/green/red lower screws. When you adjust these, go a fraction of a milimeter at a time.

How to replace Sony monitor case


I couldn?t find disassembly instructions for your CRT; however, I can give you some safety warnings and some general hints. If no one else posts at mine will either discourage you OR give you enough to start. First off CRTs are dangerous, taking one apart without the proper training and precautions can kill or severely injure you. If you don?t already have the training and experience discharging the stored energy in the monitor you should not attempt it even if you have ?instructions?. If you decided to continue on then there are typically four screws holding the back of the monitor case to the front panel. On some higher end Sony?s they are covered with a plastic cover that you can easily pry off with a screwdriver. Once you have them out then the back cover can be removed, exposing the tube and remainder of the electronics. Again a warning, unless you know what you are doing you run the risk of severe electric shock and should not proceed. Usually there are a series of screws that attach the chassis to the front panel, remove them, the panel electronic connections and the disassembly should be done.
