well first check transmitton fluid when the trans is at normal operating temps if that is normal
look at the color of the fluid it should be bright reddish color then if it is brownish or any other color than bright reddish or smells burnt you have an internal trans problem.

now if the color is reddish and does not smell burn there are numerous other things that can cause that such as clogged trans filter , shift linkage is loose or needs ajustment , or faulty shift sensors ,
or trans speed sensor that tells when to shift

When a low light or night scene is on the picture is barely visible.

open the back of your tv and there will be a small box hanging from the crt cage those little knobs control focus and brightness you can set your set in front on 50 percent or "default" and then ajust the brightness of each crt bulb behind the tv.

Picture will not remain in focus.magic focus feature fixs temporaily then condition returns

There is usually 3 flyback (hi voltage transformer) that gives the high voltage to the tube over the red wire.
On the flyback you got two adjustment. Focus and ''brightness'' ajustment. Sometimes, you can ajust from the back and they leave opening for the screwdriver entrance, otherwise, you remove the chipboard panel and adjust those screw. It usually write wich ajustment is focus directly on the flyback. As you can see its a bit of a technical ajustment, plus you have to do it when the tv is running and with the voltage on. Needless to say that its pretty easy to do a short in the electronics circuits. I hope you have someone handy with basics electrical skills. Also this might mean your tv have some parts getting in problems actually, but still it would be the first thing that i'd try in this situation... Let us know...

Hold down Fn and look at the F keys for what looks like an icon of the sun (there should be 2 of them with up and down arrows) you can adjust the brightness with them.

Can one ajust the window settings to open & close with remote.

NO this can not be done on models before 2009 and im not sure if it can on later models either. but what can be done is as follows

if you insert your key into the door lock from the outside you can open and close the windows. you may have to turn it to the lock position and then unlock and hold the key in this positoin until the windows open .
in the manual it also states that if the roof is down by turning the key in the door lock to the lock position will also close the roof the sunroof along with the windows.
