The set requires repair of cold solder connection and possible a set of convergence ic's .call for service and ask for an estimate of repair cost.

I have a question, We bought our Hatchi 50 inch tv 3 years ago

The manufacturer normally doesn't count the lamp for the warranty, but call them definitely worth checking w/ the manufacturer. Otherwise if you need to buy a lamp you can try they have FREE trouble shooting available so you can check to make sure it is the lamp.

I have a Sony 47 inch rear projection tv that is about nine years old When the set is turned on it has a good color picture but after a few minutes it tuns to a complete green sceen. Can you tell me what...

The green CRT may be intermittently bad or the focus screen block. Certain sony's are common to have bad CRT's. When the screen goes green does the set shut off?

Rear projection tv picture quality loss

most of these sets have 3 lens for the three picture tubes inside and also a mirror---if it has never had the lens cleaned they could be dusty and this will diminish the brightness and clarity of your picture---if real dirty the picture will look washed out------most of these sets you can remove the back cover(unplug set first) and gain access to the lens ; clean them with a lens cloth or a paper towel with glass cleaner.

No picture, funny noise

The funny noise is probibly the balist trying to strike the lamp. It will try several times to strike the lamp and if it is un successful, the lamp light will begin blinking on the front of the set. If so you have a bad bulb

Most of the time the picture is completely distorted and you can't make out any picture. Other times the picture is perfect. The TV is a Samsung HCN617W DLP

possibly a bad color wheel.

does it make any funny whining noises?
does it do it on all inputs?
how exatcly is it distorted? is it moving up or down real fast or is it all real funny collered?

Nice description. Is the picture still square or does it have like an hourglass shape to it? If so, one of the convergence amps has failed (common problem) and needs replacing as well probably the fuse resistors feeding power to it. Probably a job for a pro as it needs to be reconverged afterwards. Can give you DIY instructions if you are OK at soldering.
Is the picture foggy as well? Have him replace the crt fluid while he's in there. How old is this TV?
