Try adjusting the power of the blue crt by the controls behind the board in the front of the tv, should see 6 dials, 3 focus and 3 power, lower the blue and it may do the trick for ya, it did for me.

Re: kp-57ws500

Do either the red or the green crts come up at all?? If not the heaters in the blue crt could be bad - loading down the HV and the shutdown circuit turns the set off.. Only repair for that is to replace the blue crt, but I would have it tested first.. In the shop here we use a B&K467 to test for shorts and emission leaks but that's old school.. B&K has since come out with far superior crt tester/rejuvenators..

Screen turns blue and suddenly tv shuts light on front blinking

The Blue CRT is the most likliest cause and will need replacement.You can verify by removing the Blue CRT drive board if the set powers up and stays on you will know the Blue CRT is causing the shutdown.

Sony kp-57ws500 flashes blue, green, red then turns off

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

The screen on my Sony wide projection tv is turning blue after a few minutes. can you help? the model # is KP-57WS500

This is a typical bad CRT. The blue CRT part number is 8-733-647-25 but they are no longer available. It is not uncommon for this eventually to happen to the other CRT's as well. The only fix is to have a technician pull the defective CRT and have it sent to a company called VDC for rebuilding.

The screen is blue all over

Check if your red CRT and green CRT lights up or not. If it doesn't light up your CRT is no good. Because its a damn sony the picture tube is $350. I advice the people not to buy sony.

How to change CRT in Sony KP-57WS500

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)
