I have a 3 year old 57in Sony projection HDTV,when the picture is dark you can see faint blue lines in a curved arch like pattern across the screen.Any ideas? Thanks
I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. I'm not a technician but i read up on it in a repair manual and it worked perfectly and saved me a $100.00 for a service call. It took about 10 minutes to do. I also have a friend who expiernced the same problem with a different model sony projection tv and it worked for his also. Apparently this is a common adjustment that needs to be made espicially if the tv is moved.

I have a rear projection Sony KP57WV600. When I turn it on, it turns blue after a minute with blue arched lines at the top and bottom and then the flash focus blinks 5 times. the TV never comes on even though the sound is on. What could be the possible problems and how much will it cost to repair it?

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.

About six months ago, my Sony KP-57HW40 started flashing red and then turn off. The Timer/Standby LED flashed 8 times. If kept turning it ON several times, it would eventually stayed on and worked normally. About a month ago, I started seeing curving red lines across the screen when the background was black. Today, it stopped working - no picture with a moment of light blue screen and it flashed several times then turned itself off. The LED now flashed 6 times. I opened the rear panel and noticed that the RED CRT was not working at all!
I am an electronics engineer but have never worked with TV. I am afraid that my problem is more than the FBT, as I read from the previous posts. I hate to give it up yet. I really need helps. I would appreciate any suggestion. Thank you.
ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.

The screen becomes green after 3-5 minutes of switching on.Probaboly Green CRT is defective.How it be changed
CRT is expensive!!! Try to shuffle the electronic parts driving the CRT tubes first, it has three sets of parts, all are the same in each color: red, green, blue. Sometimes cleaning the leads or metal parts of the circuits, specially the green region, will gonna solve the problem. Do it first, it wont gonna cost you a dime, just time. [:0)

I just connected my Sony Projection KP-57WS500 to a Motorola DCH3200 from Comcast using a HDMI cable with a DVI connector. The picture is not very clear at all since I am expecting 1080i ouput from my HD channels.
Even though I can see the picture, I am not getting the clarity (1080i) that I was hoping to receive from an expensive tv.
Can anyone help me?
Thanks so much.

Be sure that you took the time to force the output of the DCH3200 to 1080i. They do not seem to come set that way by default! This is true whether you are using either the component or HDMI output.
Power OFF the unit and immediately push the Menu key on the front panel. Using the remote, be sure that the 2nd line of the config is set to 1080i and not something less.

There are red lines runing across the TV screen. The lines are very thin and are curved. Can I fix myself of does this need a repair by a tech? John
I had the same problem with my sony KP-57ws500 rear projection tv and thanks to the thread I fixed it in 10 minutes. At first I thought it was a white curved line but then after a closer look it was a very light green curved line. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover. The two screws at the bottom are the only screws and you just have to wiggle the facing off by pulling out and down. You will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off.
You should see 6 adjustments screws. on the top for is focus, do not touch those.
Below the focus adjustments are the Red, Green, and Blue. The adjustment is slight so turn the correct color slowly and don't push hard on the screw. I had to turn the green to the left to get the lines to disappear and it was only about a 1/32 of a turn. Very very slight. Good Luck.

When I watch my Sony KP-57WS500 TV57 in. Rear Projection Television, especially when the picture is dark, there are curved, blue horizontal lines that appear on the whole screen and are about 2 inches apart. Can anyone help me fix this problem?
Hi Guys
Your problem here has to do with the amount of aging that happens to the three colour tubes - red, green and blue.
Blue actually ages slower than red and green. What actually happens is the green tube deteriorates and due to green being the predominant colour for brightness causes the blue tube`s flyback lines to appear - especially when switching between inputs or when the video is blanked.
No replacing the blue tube will not solve your problem as the tube is actually the best one of the three.
As someone mentioned there is a way to adjust this by removing the speaker grill assembly in front of the set. Doing the service mode adjustment with the remote is not the right way to solve the problem - you would be adjusting the colour gain and off-set values and would seriously be compromising the white balance of the set.
On the left hand side behind the speaker cover you will see a black square block with six adjustment points. Look for the one marked SCR BLUE, Switch the set to a unused input so the blue lines become visible. Now adjust the BLUE point counter clockwise until the lines disappear. A small adjustment should do it, Switch back to a picture and make sure the whites are still white.
This should sort your problem. I would however suggest asking a Sony service centre to do this for you. This is a dangerous thing to do as you will be working close to the 35Kv supply the the anodes of the three tubes.
I hope this answers your question.
Goo luck.

i pressed the flash focus botton but it did not fix it
The convergence output IC's need to be replaced. That is a very common problem with all projection tv's.

I have a 2002 Sony KP-57WS500 that occasionly (randomly?) flashes red lines and then goes to a full screen red while giving an electrical "cracking" sound before shutting down. Once shut down, the red power light blinks 8 times in a cycle. Any thoughts? I have unplugged and moved the plug to a different outlet.
Seems like your RED CRT is shorting out or failing. Do you notice any other colors besides just red having problems? The blinking of the red light eight times is a High voltage error. It could be your D board but I'm thinking it is more likely the red crt is probably shorting out.
