Question about Sony KP-43T70 43" Rear Projection Television
Hi, I have a Sony KP-43T70 it is 7 years old and I'm the original owner. My problem started around a year ago but it is getting worse, the picture looks fine some of the time but when there is white in the background the pictures look like they have a green ghost. I have cleaned the lenzes and wiped off all the dust on the mirror but it is getting worse. Have I done something wrong in the hook up? Thanks for all the help.

The cause of the problem can be that the CRT-s are getting weak. Life span of CRT is around 30000 hours of working time. Please calculate. If you need more info please advice.

When was the last time you adjusted the convergence on your tv? It is possible it is a bit out of adjustment.... and do not over adjust

Hi, Thanks for the reply. I'm new to this board and I do not know what the CRT-s is. Please help again. Thanks Jay
Thanks I will see what I can do about having someone check that problem.
Hi, I have done that many times, the + also shows the green. I even opened the back, wiped off all 3 lenses and the projection mirror, that did not help any. Thanks for all the help.
I have also stated to get green ghosts. What would the average repair cost be to replace the CRT ? Is it something that a somewhat competent person could do?
A friend just gave this TV to me, and the color seems to be way off. Everything is too red, no matter what I try to change. The problem seems to be that green is not rendered correctly. Things that should be green are not, but whites have a green ghost bleeding to the right.
the right side of my set looks good, but as you look to the left you can see green and red ghost images. it gets worst from the center over to the left
