Sony KP 51HW40

Everybody is having the same problems with this TV all at the same time. Do you know if we can all get together and do something? Do you know if there was a recall on this?

    its the kp-57hw40 but the manual lists both the 51 and the 57...no matter how i hook it up..it fades to blue screen. Sometimes I get a momentary glimpse of the menu but not long enough to change anything. The sound is good. Its like a giant night light at this point. They should have said the life expectancy of the thing was 5 years and they should have i
    ncluded funeral expenses in the price.

My Sony KP-51HW40 is underscan!


If you have already changed the aspect ratio on your TV, then change it on your cable or Sat box. Your TV appears to be operating normal.

KB-51HW40 blur with different colors layers


Its called the Convergence. Its likely a device on one of the main control boards is failing. these are a common issue on the projector tv's usualy it will be a whole board replacment, OR componnt level trace and replace. This is something unless you are familiar doing can be quite hazardous. If your not sure get a local shop to give a free estimate, all my projection tv's have done this with time, you can even go into the menus and realign it through tv settings, but sometimes they will start to wander out again.

Screen shakes / jumps vertically on my Sony KP-51HW40


The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

I read it online that this is a very simple problem. It needs highvoltage splitter. I tried to open the front panel to see where the splitter is. However, I need some hint as to how to open the front panel. Good luck. Kiran
