Blue streaks, looks like a spill from the top

We just recently replaced the bulb. Since then, the longer the TV is on the brighter and bluer the streaks running down the screen become.

My dad has Sony Model KDL-42V4100 that is about 3 years old. It has a smoky vertical streak that almost looks like water has run down the screen---any ideas on what it is or how to fix it. It appears...


This is called "clouding". It is very common with a lot of the lcd panels. I suugest going to sonys e support website to see if it might still be under warranty. I have a sony lcd tv that I purchased back in 07 and its under warranty until october 2012. If it is still under warranty then sony will fix it for free.

Your really messed up
First ,get an owners manual,if you don't have one already
Then always look up what the bulb or lamp # is,BEFORE you buy them. Looking up fuses and bulbs,is the main reason you ,absolutely need the owners manual.
You also need one, so all these silly people,stop asking what the check lights are for.

Blue wide streaks in my 42" Sony TV model KDFE42A10.


I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.

What lamp did you replace it with? Some of the aftermarket bulb sources are not the original brand and do not work as well.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
