Question about Sony KP-57HW40 57" Rear Projection Television
Posted by Anonymous on
SOURCE: Sony 57 in Rear Projection TV
If the picture is playing fine and you notice that the background is getting more and more red, until it is too red and the set shuts down, it could be that the red screen control is set just a bit too high. If this is the case, you can probably correct this yourself. If you are watching a perfect picture and then it suddenly flashes a very bright red, with thin red lines in the pictureand then shuts down, it usually means that the red picture tube has developed a short in it, between the cathode and heater. A good tech might be able to remove the short by arcing, but if the short persists then the red tube will have to be replaced. Either way, this is something that should only be done by a qualified tech.

6 blinks is usually associated with failure of the horizontal
deflection amplifier - which shuts down the high voltage system as well.
The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).
most of the time it's the horz. transformer and transistor.

I found this solution from SONY's website.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
I hope this helps.

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.
