My XNR200 is about 7 years old. Recently, the color in the lower left corner is green. For example, when watching a hockey game with a white sheet of ice, the lower left corner of the screen is green - about 12" tall by 4-6" in. I've reset everything and turned the TV off for 24 hours. It is still gree in the corner. Is there anything I can do to fix it?

Re: KV-36XBR200 Green in lower left corner
The most common cause is, shadowmask inside of the CRT is magnetized. It sounds by your description that the TV's internal degausser for the CRT is not working. This is serviceable by a service tech.
Most of the time the cause of a failed degausser is the thermoresistor. This is a common type of failure.
Another cause that can show the fault you are seeing is if the shadowmask in the CRT is defective. Sometimes the mask is damaged when the set is being moved, and is accidently banged against something. The CRT is sensitive to this type of treatement.
If the mask inside of the CRT is defvective, the only fix is a new CRT.

Hello; You probably have a CRT type set. Something has magnetized your CRT/Picture tube. The set has a built in degaussing system that will only work when you turn on the set when it is COLD ONLY. If after several cycles of turning on the COLD set and the green color hasn't gone, the circuit in the set for doing this has failed, OR you have the set near strong magnets, such as speakers. PUT ALL speakers at least 4 feet from the set and go through these off on COLD cycles. The deflection yoke on the picture tube could have moved due to Sony using crappy adhesives to hold the yoke positioning wedges in place. I am so glad to be done with Sony!!!!! John
It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.
for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.
Move any speakers or electrical devices away from the set. It could also be anything electronic or magnetic. Anything near the set that generates a magnetic or electromagnetic field could be causing the distortion.
Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
I recently got a similar TV with the same problem i thought my brother had taken something with a magent in it and sat it on top of his old TV when i got it it had the dis color up top right,
Well like most TVs you take a magnet, and it will change the color somewhat,
Well i tried it, tried to get the color as small as possible, carful not to get too close to the screen, i got it pretty close to being gone somewhat, and i turned the TV off, well i turned it back on, and guess what, the spot was completely gone, and never came back,
I suggest to try this ONLY if you have no other solutions to your problem,
im just stating what worked for me, and im not a tech,
Problem 1. Color patches at lower corners. These are caused by magnetic sources close to the TV. Do you have any Speakers close to the sides of the TV? Are they Magnetically sheilded? No? Move them away from the TV. Problem should then resolve itself in a couple of days.
Problem2. Screen Slumping. Most likely a problem with the Pin cushion correction ckts. Get a good technician to have look. cost should not be much. Under 100$ plus Technician fees.
