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

1 Answer

Green Arcs My TV is about 4 years old, I have had green arcs across the screen for a while now, and just today the screen would flash and go all green then shut off and the standby/timer light flashes. The green arcs change positions when I play with the wide mode. Also when this problem first started I would get a flash of red when the set was turned on and when turned off. Just noticed it doesn't do that now. Any help would be greatly appreciated. Thank you.

    I tried the fix for the lines from another post "Faint blue arched line across picture" and worked great, the green arcs are gone. Unfortunately, after about an hour of watching the set it still flashes green, the screen goes all green and the set shuts off with the timer/standby light flashing.

    I have the same problem with the green arcs, then green flash and shut down. Sounds like the CRT's will need to be replaced by what you've indicated. My brother gave the TV to me. Is it worth fixing? How much are the CRT's?
    Serial # is 9004851

    I have a Sony KP-WT46-500 rear projection TV with the same problem. Unfortunately, the set went out completely and does not stay on and I don't get any picture Sometimes I get a blue screen, sometimes I get a light purple screen with several pink and purple arcs. I hear 1-2 clicks then it shuts off and the red standby light blinks. .... any ideas what is going on? Is this worth repairing?

You will need to have all three CRT's replaced. This was a common issue with this year of Sony projection TV's

    Depending on the serial number on your TV, that will determine the availability of the CRT's. I have done some recently where only the red is available but, the green and blue have to be pulled and rebuilt. Post your serial number and I can research the pat numbers you need.

Projection TV no picture flashing horiz arcs across top of screen sound okay

You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

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!

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.

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!
