    it looks like T801 is bad (singing quietly) any idea on where to get parts ? unsure if the part has a pn# on it.

    awesome, thank you for the help. i'll be ordering next week. one other question , which end does the flyback unplug from ? the flyback side or the distribution block side? i've pulled on it from both as hard as i dare (or think i should have to ) and it's not comming loose. i would assume it comes unplugged from the distribution block side but i could be wrong . Thank you again for all the help.

    disreguard last , i got the flyback out and off the board the pn# on the flyback is 8-598-928-01 will the pn# you gave me work? or do i have the newer superceeded#

    Thanks :)

    ok we received the flyback (thank you) and replaced it , no more singing but still the same problem . which board would be the vertical board? all fuses are good in the unit and nothing obviously blown was found. the power light blinks 3 times on power up and the screen is bowed / compressed from the top and bottom into the middle of the screen. the information (picture) is not steady either. we'll keep going until we get her fixed lol

The vertical circuit needs to be checked. It could be the vertical output needs to br resolderd or you could possibly have a bad capacitor. if you need more assistance let me know.

    You can get a new replacement flyback at the other site that work for as a support tech . you need flyback number 145318911 for your model its 65.95 and that includes taxes and shipping. they also provide free tech support with online instant messageing incase you need some tech support. I had Dawn move the flyback to their front page so you could find it easier. Heres the link.

    If you order through the link I provided send them an email with that number and they will do a cross reference on it so you get the right one for your model, they will need the serial number of your set also.

I am having trouble adjusting my colors for my kp 53s25 there seems to be a lot of yellow how can i solve this?

This TV has had a long life. Your picture is looking more yellow these days because the Blue picture tube is wearing out. Not saying the Green and Red tub are much better, but Blue tube is a major player in the picture brightness and white balance (the color of white which the TV reproduces). The cost involved wouldn't be justified. You should enjoy the balance of the TVs life; when it's time comes... have the new TV delivered and ask them recycle this one. Best wishes.

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.
