My sony KV XBR 250 tv stopped working after I moved. The sound works but the screen will not turn on

SOURCE: sony tv picture keeps flashing

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.

posible solution is adjust the screen to low.also check the trimer if it is working.check the resistor in the heater line...weng

for my post #108 for a step-by-step solution with pictures. $21.83 is all it cost me. I fixed my own TV as many others on that forum have. Feel free to contact me at [email protected] if you run into difficulties.

Hello, my TV was dropped (rolled forward) and experienced the same problem. The shadow mask has shifted. In general this shift should be localized to section of the screen (usually the top). I managed to fix the problem using an array of magnets. It took a few days to arrange the magnets to compensate for the shifted mask. I used 10 strong small circular magnets. The picture has normal color but has some nonlinear streching (barely noticable) near the top of the screen.
Hope that helps if you need more advise try me at [email protected].

sounds like you have some cold solder or bad joints,power section, inspect it ,with the back off, but be carefull.........i had one that did that...bad connection in solder joint...had to resolder,if you have to resolder,make sure it is unpluged.hope this helped....
