Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television

1 Answer

Fade to Blue (same as Green Arcs?)

I shall assume that my problem is similar in nature to the "green arcs" problem. Bummer. Tyvek's (sp) solution for green arcs will probably be the same for my set (CRT replacement). The screen image is perfect when I turn it on, but then the fade to blue happens, 100% of the time, for 30 minutes. TV is also turning off by itself, like others. If we leave the set on continously. the problem is mitigated.

Re: Fade to Blue (same as Green Arcs?)

You can turn the Screen controls down a little bit, but I suspect you will need to replace all 3 crts as most of these crt arc sets require all 3. EXPENSIVE if crts are even still available.

When i turn it on the screen turns green then blue and then shuts off

This is one of a group of sets that had bad picture tubes (RED, GREEN AND BLUE).

The tubes are no longer available from Sony and only available on a rebuild basis---very expensive.

There is something easy that requires no parts you can try in an attempt to cure it. Takes about 15 minutes and I can tell you how and what to do.

If this is of interest to you rate this solution as very helpful and comment here and I will assist you.

When the display is dark i get red and green arcs on the screen


Color arching is an easy fix. You need a screw driver and some patience removing the front panel. You will be looking for a box with 3 screws on it. This is the color gun. THe scews are Red, Green and Blue color only, however, they usually don't indicate the color on them. Turn the screw (Slighlty) till the arching is no longer there. You have to do this with the tv on.. LOL

I expect the answer to your question is YES! The convergence amplifiers are a common problem in many projection sets. When you search for the replacements you should find that the originals have been superceded by improved parts. Also be aware that when these parts fail, they will usually damage a resistor in the convergence yoke return path. The resistor must be replaced with one of the correct value or the convergence, though responsive, will be out of range.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

Green Arcs Problem continues

That model is older than 3 years old. If the lines are mostly visable when you select an input (video 1,video2 etc) that has nothing connected to it and they appear as faint lines that go diagonal then an adjustment wont cure the problem. Some of those set had faulty picture tubes from day one. You might only see green right now but in the futire the red and blue will start showing the same symtom. If pressing the flash foucus and goes through the process successfully then your convergence circuit is most likely ok. The CRT's range in price and now in most cases the blue and the green are no longer availiable and have to be pulled for a rebuild. I personally wouldn't suggest anyone go into the service menu unless they know what they are doing.

Green arcs from bottom up with darkest one at bottom on dark screens

there is a way to get rid of the lines, you need to enter a code from your remote to access a hidden menu. From there you can adjust the lasers in the tv(green lines)I beleive it is very sensitive though, if done wrong can reck the tv. Not sure of the code or directions on how to exactly adjust the lasers, actually looking for them my self. Hope i was some help though!
