Re: 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.
