Question about Sony KP-57WS500 57" Rear Projection Television

Sony KP-57WS500 cutting off

I am adding to a posting i placed a week or so ago. When i cut on my tv and just have the video screens showing, it is a light blue screen with arced lines in the picture. In the 15 seconds it stays on, i can scroll through the video screens and see this on all of them. When it gets to the non-video screen, it just looks like a normal static screen. I was told by a tech i called that this may be more than a flyback transformer on the d board. Can i get a second opinion to what this could be or if it is still the transformer. After it shuts off it gives me a diagnostic code of 8 flashes.
Thank you

Since you get a picture for a while, it is unlikely to be either the flyback or the horizontal output transistor as those would not allow a picture for any amount of time. You would jsut get the 8 flashes. This sounds more like an over voltage problem that could be in the regulator circuit. I'll look up the service manual on this one and get you more details.

THE LED ON THE FRONT OF THE SET SHOULD BE BLINKING IN A SERIES OF BLINKS THEN PAUSE AND REPEAT THE SEQUENCE. IN ANY CASE IT NEEDS TO BE SERVICED BY A SONY AUTHORIZED SERVICER.

Get them back out there and and make them fix the problem. Obviously it was not properly serviced. $800 for a repair that didn't take is a rip-off. If they refuse, report them to your local BBB and post negative feedback on ripoffreport.com, angieslist.com and as many other places you can come up with.

BLUE SCREEN


I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
