Sony KDF-E55A20 Pink vertical lines

Hi, I was given the above TV by a friend the other night because it was diagnosed with a bad optical block and he chose to replace the TV instead of repairing it. I had to transport it face down when I moved it from his home to mine. When I plugged it in and powered it up it played perfectly all day. However, when I turned it back on later on, the screen was filled with pink vertical lines about a half inch wide and all across the TV screen. If the optical block was bad, why did the TV work fine for a while? I'm thinking a bad connection or a loose circuit board may be the problem. Do you have any suggestions on where to start and are there any common problems with these TVs that have the same issues as I have described and if so, what was the repair? Thanks

Dear, the circuit for controlling speed is affected and that circuit is composed of passive componets inductor, resistor and capacitors. the only possibilities is to check loose connections a round the line transformer and around the vertical section. also check and measure the values of your electrolitic capacitors, cause these also change values when wax finishes in side them.
check that and contact me for the out come.
thanks for asking fixya.
okay.

I have a KDF-55E2000 Sony Grand VVEGA Color Discoloration


Bad news: The issue can only be solved by replacing the optical block for the TV. This was a defect in the design of this TV. Replacing this part is very expensive (over $1000) and time consuming (need to take whole TV apart).

Good news: Sony extended the warranty for the optical block for this model. They are covering the cost of parts and labor for this TV. Contact Sony to have them refer you to a authorized service center near you.

The lamp?


Hello,

This unit does not contain any CRT's. This unit uses a Optical Block Assembly to produce images on the screen. There is a lamp that is user replaceable for this model (KDF-E55A20). You can find the lamp for this model listed below.

6 red light blinks-possible thermal fuse prob.


The thermal fuse is located under the optical block. However the optical block needs to be removed to replace it. So unless you are very familiar with the disassembly of this tv I suggest you have a Sony ASC to do the repair work for you. You don't want to take a chance of damaging the optical block.

I want to clean the projector sitting in the back as I see that there is some dust on it. I dont know if that is a good idea or not or if it will even make a difference with the image on the screen. I want to take a pc of cotton and windex to it while I am waiting for my thermal fuse. Anyone with advice?
