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 rear projection kp-577hw40, screen turns red after being on for 10 minutes

This model and some others had bad picture tubes that are no longer available---there is an option here.

If screen gets bright red, green, or blue set will shut down as it detects too much current being drawn.

Seen over 100 with this issue--what can be tried and usually will help is a physical adjustment inside the set.

No parts to replace and takes about 15 minutes to do.

I can tell you how if you want to know.

The screen turns blue after about 2 minutes of turning on the TV

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.

I have a Sony KP-57WV600 projec. have picture for 10 seconds then screen turns blue for 10 sec.then black and I still have sound red light does blink but I dont know how many times. Called Sony they told...

You have a shorted blue CRT (picture tube)

The problem is that these TVs are known to have defective CRTs but Sony can no longer supply them. There is a company in Texas that rebuilds them, but its an expensive repair.

Its a shame that Sony has not been forced to take care of their customers. I've replaced hundreds of these CRTs and seen hundreds more after the supply ran out.

Sony knew about this issue way back in 2002 but only resolved complaints for a limited time and did nothing to notify owners whom they could easily indentify by serial number.

Let's hope we don't give up our auto industry or we'll soon see the same behavior there.

Blue Screen and TV shuts off

Here's a shortcut to what the blinking codes mean.
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here:

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.

Blue Screen and TV shuts off

Yes, you are correct on the phrasing. The CRT's were a common issue with these units and all three must be replaced as sooner or later the green will follow the other two CRT's. It was a great model and had a beautiful picture when operating normally. The CRT's are costing about 200 each for rebuild as the green and blue are mostly no longer available. Your repair cost are going to approach $1000.00 or more.

After 5 minutes of good use screen goes redish color

It certainly sounds like the Red CRT (picture tube) has heater-cathode leakage and is not likely worth repairing, as all 3 tubes usually have to be replaced at the same time for best picture quality.

There is a good possibility the green picture is arking and making the set turn off,SOMETIMES if you pick up the set from the ground about 3 inches and then drop it takes care of the problem,then the same symptom becomes intermitant or goes away for a long time,replacing the picture tube is a lot of work and then it needs to be adjusted completly that is why the high labor,If you decide to try it dont over do it,if that does not take care of it the only solution might be to replace the picture tube.Please let Us know if you need more information.
