Solution: 

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in or warped.


Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix. 

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. 

Everything you need to fix it yourself. 

Hi Tracy,
I have the sweetest grandchildren and tey are always willing to help also, so we have to love the children for all their wonderful help. ( NOT !!! ...lol ) But lets not send your son to the adoption web sight just yet. I'll start by letting you know ( in a sigh of releif for you ) that your tv is not damaged forever, although, when the windex drys, you will probably see a dirt stain on the screen, since the windex probably did it's job and cleaned the dirt off, unfortunatly the residue is between the screens. You have 2 layer of plastic screens for your TV. One is a lexan shield and the other is a riffled substance plastic. To seperate the two of them, you need to take the front of the TV off, normally by removing screws from the inside of the TV ( this can be a tricky job and I really suggest you have a pro do it if you haven't worked on TV's in the past ). If you do it, be extra careful not to break the screen or sheild after removing as they can get a bit pricey. When you take them out, they will seperate ( one lays on top of the other, no real trick to them ) and then just grab your windex ( the remains of the bottle that your son left you ) and clean them like you would glass. Of course after you clean the screens, replace them in the oppisite proceedure of taking them apart and wella, all is ok again and junior remians a loving and helpful son. smiling. I hope this helped. Nice day.

Needs convergence IC's replaced....

It is convergence problem and convergence ICs need to be replaced.
If you have basic electronics knowledge and bit experience of big TV repair, let me know to guide you further.
Thank you.

It is convergence problem in your tv you need to replace the convergence IC .

The convergence setting is not proper in your tv . You need to access convergence setting through service menu .

i know this isnt what you want to hear but your best solution is to call a repairman in.if you dont know anything about tvs and ask people on here they will have you so confused and have you spending moey you wont need to be spending on parts you dont need.if it were my tv i would call in a repairman and let him fix it right the first time so you dont have to do alot of running around looking for parts you may or may not need.

Line across screen is problem with LCD Panel. It is not user operational problem.
I hope TV is under warranty so call Sony for warranty cover.

If the D board didnt correct the convergence issue the problem has got to be the wave generator on the A board or possibly the Velocity boards themselves that are bad.

the pico fuse are the two little yellow resistor looking things under the heat fins of the convergence chips

How many flashes? Is it continuous?

If you count the number of blinks, then go to this site:

http://www.iwaynet.net/~nesda/SonyBlink.html

you will get some idea of the trouble. But, continuous blinking is usually associated with the "jungle" chip which is not a clear and easy cure; it must be further diagnosed by a tech; repairs are probably over $200.

i would have a shop reconverge it.thats going to be the easiest way to get the picture back the way it should be.
