I contacted a sony repair facility and they told me that I would need a red tube because they dont rejuvinate any more, but the problem is that the red tubes are discontinued. Do you know how to get the red tube for this tv?

Re: screen turns red after 10 minutes
First, lets see exactly what is happening and what is causing it. If your picture starts out fine, and after 10 minutes or so you notice that the picture is getting redder, and the redness slowly gets worse and worse, until finally there is red everywhere with faint curved lines, then chances are your Red Screen control is set just a hair too high. This is a very simply thing to correct. If, on the other hand, the picture is fine for 10 minutes or so and then suddenly flashes very bright red, followed by the set shutting down, then your red picture tube has developed a short in it, usually between the heater and cathode. A good tech might be able to remove the short by arcing. What is your set doing? The KP-51WS500 is one of the newer 16x9 1080i HD sets and the tubes are available from any Sony distributor. When they told you the tubes are not available, that was their way of saying they do not want to bother helping you. The Sony tubes are quite inexpensive, costing about $175, and they come complete with sealed coolant chambers, so replacing a tube is quick and simple.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.
IF THE SCREEN IS ALL RED WITH VIDEO VISIBLE AND RETRACE LINES. ADJUST SCREEN CONTROL IN THE FRONT FOR THE RED TUBE ONLY. TURN CONTROL COUNTER CLOCKWISE. IF THAT DOESNT DO IT THE TUBE CAN BE REJUVINATED.
It sounds to me like you have a problem with the sony tv. In many cases I have ran into a problem like this. If the tv blinks a certain number of times it is a defect code intended to direct the service person to the problem. I am almost posative that five blinks usually means that there is a problem in the screen circuit or picture tube. If you noticed any discoloration on the screen it means the tube has weakened, but don't lose hope. Sometimes when this problem occurs you can save the set by having your local repair center rejuvinate the picture tube. Using a piece of equiptment designed to burn debris from the filaments, a picture tube restorer/rejuvinator is your best bet in this case. One more side note, you can usually temporairily solve this problem that you are having by slightly adjusting the master screen control located on the flyback transformer, (which is the large, dark colored object with the big red wire coming from it and feeding high voltage to the tube). Hope this information is helpful to you and feel free to contact me if I can further assist you, Russmann.
ON THE 36 INCH SONY THE PROBLEM LIES ON THE PICTURE TUBE.THERE IS A LEAKAGE EITHER HEATER TO CATHODE OR G1 INSIDE THE CRT.THE ONLY WAY TO FIX IT IS REPLACE THE CRT OR HAVE THE CRT GUNS CLEANED THRU PICTURE TUBE TESTER/RESTORER/REJUVINATOR AVAILABLE ONLY FROM TV TECHNICIANS.GOOD LUCK.4TUNE.
i too have 57wv600 and your problem is same as mine VOLTAGE withen tube is off ...this is common problem sony knows full well and will not tell us this voltage can be adjusted with a philips screwdriver i had blue lines then solid blue then shut off...7 blinking lights ...went to this site followed directions (too simple)and now i have perfect picture.serviceman said i needed new tube.b.s. ...so never change your tube it is not the prob!!!!!!!....go to www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html read post(comment) near bottom of page by paul t dated 12/26/2007 and instructions on how to remove our front panel is fully explained ...a screwdriver will fix your problem I guarantee it.....
This is the classic symptom of a CRT (picture tube)that is starting do get weak. The picture takes longer and longer to come on, it appears greenish and blurry, and it blinks on and off in different scenes, and when it is off the timer LED blinks 5 times. Sony has a circuit called "IK Blanking" which monitors and adjusts the colors in the picture tube, and shuts the picture off when the tube is getting too weak. The good news is that the Sony tubes always respond beautifully to a CRT rejuvination (recharge), and the picture returns to perfect. Since the set is 36 inches and VERY heavy, it should be serviced in-house and an appropriate charge for a service call for your set should be around $150.
donot quickly replaced the tube! try this first get 2 megohms 1/2w resistor solder it between blue gun and green gun.if this make the picture still, bad tube.u can still rejuvinate it.if not,bad capacitor in vertical or bad g2(screen) adjuster.
