Hello..We replaced our tv when it went out a couple years ago, but were hoping to perhaps get it fixed now if it's not too costly. I can't remember exactly what happened, but as I recall when I turned it on one day all the color zoomed in to a small dot in the center of the screen and was out after that. The power light would stay on, but the screen would stay black or perhaps had some wavy lines in it. I don't remember for certain, but do remember thinking a picture tube or whatever a projection tv has must have went out. I had called for service, but was told it would be quite costly just to get an estimate. Do you know what this could be caused by and how much we could expect to have it repaired? Thank you!

Re: Tv doesn't work
If your projection went down to a single dot in the center then you are most likely at the minimum replacing all three projection tubes due to that dot. It will leave a permanent mark in the center of each CRT and not repairable. The cost on that old set aren't worth it.

I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps
Yes the Ics are easially replaced if you can solder. You will need two STK392-560 Convergence ICs and possibly the 12 4.7 ohm 1/2 watt resistors as Sony sets will usually weaken the 4.7 ohm. You can get the replacement ICs ad resistors at the following link and they provide free instalation instructions with picture as well as free online tech support in case you need additional help.

My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.
Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.
Camaroguy: This exact problem happened to us about 8 months ago. A board had to be replaced at a cost of $500. Yesterday, the convergence has gone on the set. You get a blue and yellow shadow on the picture. From what I have been reading, this has happened on a few TVs and it will cost another $500 or so. We refuse to pour more money down the drain so we just went out and bought a new plasma (RCA) for half what it cost us for the Panasonic 4 years ago. We have never had a problem with RCA in the past (two tvs for 20 years a piece).
