Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Red Bowed Lines / Red Hue

I have noticed it more lately that during dark screens or no source screen you can see a series of arched horizontal red lines spanning the entire screen left to right, top to bottom. This is also accompanied by red hue overall!! They are present all the time but only noticable in dark areas or dark screens.. help

    I'm also having the same problem but today it seems like the red and green are both out of allignment. The tv hasn't been moved so I know it wasn't jarred at all and the allignment button is not working.

I tried the solution that was posted for this problem and it worked!
Just remove the Low front panel by removing the two bottom screws that are covered by two screw covers, then remove the second panel (black) by removing the 4 screws then you'll notice a module with 6 adjustment knobs, get a small screw driver, and with the t.v. on, being carefull , and with somebody accross the room looking at the screen begin with the lower left knob and turn left very slowly and ask the person across the room to let you know if the screen is better or not, after this I had to adjust the green as well so, I adjusted the next knob over to the left. Do this adjustment carefully and try to remenber the original position of the knobs in case you have to go back.f
Good Luck,
Californian.

Blue and red arched lines on screen when background dark


Sounds like you are describing retrace lines that could indicate that your CRTs or something in the drive circuits are bad.. Check the resistors on the CRT sockets to see if they are in tolerance. If they are try turning the red and blue screen adjustments down just a little this should take the lines away. You will however be needing service in the not to far future. Turning the screens down should help if the resistors check out. Let me know if you need anything further.

White arched lines appearing on dark/black screens.


it sounds like you are seeing the vertical retrace for all three colors together (white). Its possible that all three screen adjustments (red, green, blue) are off, but I suspect a problem with the screen power supply.
there is also a recall on this set

Very fine red lines across srceen


It is an adjustment, but it's an adjustment you may not want to do. It's the red screen control. It's located behind the front panel so the entire front panel has to be removed in order to access it-which will expose you to hazardous voltages. if you like, I can post detailed instructions on how to get that front panel off, it's kinda tricky.
