Re: Trouble

Rookietec, I have the same type of problem with our Sony 51" KP51HW40 as well as thousands across the country. I have done a lot of research on this and have been in contact daily with Sony and my area service dealers. This is what I have found: The green, red, and blue picture tubes are filled with a material that is defective. When this material eventually gets overused (after a few thousand hours of use) the TV senses "something is wrong" and automatically shuts itself down. Sony is and was aware of this situation back in production and even changed the type of tubes they used but the new ones weren't any better. Sony established an extended, limited warranty to cover the cost of repair for this well-known problem but at this point the picture tubes are no longer in stock to provide repair. According to Federal law, manufactures are obligated to replace with equal or greater value product if they cannot provide repair on something they know was defective. My suggestion is to visit to report a consumer complaint to the Federal Trade Commission. I just did this morning and it took me about 3 minutes - very easy. Turn to Sony and ask to "Escalate your complaint" to higher levels because Call center reps are not in a position to help you. You start to get somewhere when you get a Special Event ID # and reach the Tech Rep department. I have been in contact with a few people that have been very persistent and stuck to there guns on this and they have been able to get an upgraded new TV for the price of what the repair would have been if Sony had been able to repair the set. The entire process for these people took about 4 weeks. I'm in week 2 and feel like Sony if finally being receptive. Hope this helps, feel free to contact me for any additional information at BadSony

KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down.
This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.

Sony KP-53HS10 rear proj TV - picture goes on & off

If the adjustment of the screen settings does not fix your problem, its likely that one or more of the CRTs (picture tubes) is defective.

And, the CRTs for these sets are hard to find and expensive.

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

It sounds like your red tube is going out. Fairly expensive piece but easily replaced. They run anywhere from $250-$350.

Picture is geen and does not stay

Lots of trouble with bad picture tubes on that model! Remove the front grill and very gently tap on the neck of the center picture tube near the socket with the back of your screw driver. If the picture flashes back to normal that means the the tube has an internal short. You may hear a snapping noise while tapping and the set may shut off. If the tube is not sensetive to tapping it it possible you have some other type of failure.
