Question about Sony KP-51HW40 51" Rear Projection Television
I have a 4 year old tv and when I turn on my tv the picture shows after a couple minutes the screen turns blue and I can only hear sound. I read it might be a blue tube problem and sony knows about a manufacturers defective tube. How would I know if its a manufacturers defective tube. If sony doesn't change it for me, where can I go to find a blue tube for a low price.
I had just adjusted the lower right adjustment on the screen focus block. 1. Remove the front speaker panel (there were 2 screws) 2. After the panel is remove, unscrew the sheet of plywood that's held together with 4 screws, this will expose the TV's innards (guns, etc) -- be careful. 3. At the bottom, there's a small box with 6 adjustable (via a philips head screwdriver) screws. Disregard the top row of 3 (they're for focus). 4. What I had to do was adjust the left most one ever so slightly with my philips screw driver. It seems the TV was over-firing blue causing everything to have a very slight blue tint as well as the lines. Once adjusted, the TV was good as new.

The CRT's are the most common problem on those sets and if you have to replace one, plan on replacing all three otherwose the other two will follow shortly. This was a defect in the CRT's and Sony did cover them up to 4 years from date of purchase.

Could be a blu tuibe but also i've seen many bad sony CRT Drive bds(the circuit board connected to the neck of the tube). You won't find really any place cheaper than the next if your a consumer. just try partstore.com Oh, and forget about sony paying for it 4 years is way out of warranty.
