Sony kp-57hw40

It is a set with issues with the 3 picture tubes but it is quite likely if you locate the red screen control and turn it down just a little you can correct this problem.

No picture comes up but tv powers up and the stand-by light blinks for about 3 to5 seconds, i also hear sound when i turn it on and change channels

If in shutdown the power light should continue to blink a specific number of blinks which is a error code.This set is prone to bad picture tubes (has 3) so depending on code may be a fatal issue----sets will before flash bright red, green, or blue when this happens and shut off.

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.

Sony post convergence repair problem

The flash focus is a joke in these sets--only adjusts a limited area and can make the set look worse--like having a cigarette lighter in your car--not really needed.Flash focus rarely if chips have been replaced will SAVE the adjustments.The set stores the convergence adjustments on a board inside--best way to adjust is with the Sony remote to enter the tech menu and adjust there--when done one of the numbered buttons is pressed and Save? in red appears--press same button again and it goes to green which means adjustments have been stored in the set.The tech menu will also always give a much better adjustment of the entire sceen.
