Blue streak of light running through the screen when watching tv.


Hello,

When a blue streak of light is running through the screen of your television then the problem is most likely from your main board of your television or the t-com board.

You can open up the television with the appropriate screwdriver, then assess the capacitors to see which is faulty, and if none is swollen then the problem is not from the main board.

Then replacing the t-com board will do the job.

Take care

I have blue hazy streaks and tiny blue dots on my lcd tv


You need a light engine. I do not remember if your model is still under Sony's recall. You might want to call them.

Blue streak and no red on Hitachi 50V500A rear projection TV


Check a second source such as a dvd player or game system using different cables. If the same issue happens then the tv will need repair. However if the issue is not the same it is either cables or the original source.

Blue dots and streaks


Blue streaks might have been just your video connection and problem with signaling. But, blue dots is faulty light engine, aka "optical block". The engine in this could be a defective LCD array. Very expensive, a optical block is about $850. Hope it's still under warranty. You could get a rebuilt one, possibly. Need service adjustment too. Bad problem that Sony has with these kinds of sets.

Blue streak and specks


The Optical Block is the problem. Call Sony at 1800-222-SONY and see if they could help with the repairs due to the cost of the repair. I estimate it would cost 1,200.00 to 1,500.00 to get the job done.
Hope this helps,

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

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.
