Cathode ray tubes (crt) for a Sony Rear Projection TV Model# KP-65WV600.

This is a CRT(cathode ray tube) not a bulb. A Bulb is totally different. If you replace one Tube, you need to replace all 3 or the colors will never match properly. However, This model no longer has parts available. Even if they were, the cost would be close to $1000 in parts. I would not recommend repairing this TV.

Hi, if the tubes fade from full brilliance to black over a few seconds, the possible sounds like dry joints in the CRT heater circuits. possibly caused by dry joints (bad solder joints). Most repairs involving rear projection TV's can be a pig (mainly relating to access to work on the circuit boards)

Turn your screen drive down to green and blue tube.
You have a focus/screen drive control block that you can adjust each tube R/G/B

sounds similar to mine (blue) I am told its a faulty crt blue tube.

It is not unusual for the CRTs to cause this problem. In this case the Blue CRT. The problem is that you cannot get them anymore. You must send the CRT assembly to Sony for them to rebuild it. Due to the age of the set and the cost of this process, I do not recommend repairing if it is the Blue CRT causing the problem. The only way to be sure is to have a professional check it out.
I hope this helps,

A CRT is the Cathode Ray Tube (CRT) or picture tube. That model has been known for the green tube shorting. Its not too hard to replace a CRT if its done safely and correctly but they are kind of pricey to purchase. let me know if you need any further assistance.

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.

I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
